Introduction to VMware vSphere
Virtual Machines 1
This information introduces the concept of virtual machines and how they function in the infrastructure
environment with vSphere. You will find information about what constitutes a virtual machine and the features
available for managing them.

This chapter includes the following topics:


n “What Is a Virtual Machine?,” on page 11
n “Virtual Machines and the Virtual Infrastructure,” on page 12
n “Virtual Machine Lifecycle,” on page 12
n “Virtual Machine Components,” on page 13
n “Virtual Machine Options and Resources,” on page 13
n “Where to Go From Here,” on page 14

What Is a Virtual Machine?


A virtual machine is a software computer that, like a physical computer, runs an operating system and
applications. The virtual machine is comprised of a set of specification and configuration files and is backed
by the physical resources of a host. Every virtual machine has virtual devices that provide the same
functionality as physical hardware, and have additional benefits in terms of portability, manageability, and
security.

A virtual machine consists of several types of files that you store on a supported storage device. The key files
that make up a virtual machine are the configuration file, virtual disk file, NVRAM setting file, and the log file.
You configure virtual machine settings through the vSphere Client and should not need to touch these files.

Table 1-1 lists the complete set of files that make up a virtual machine. A virtual machine can have more files
if one or more snapshots exist or if you add Raw Device Mappings (RDMs).

CAUTION Do not change, move, or delete these files without instructions from a VMware Technical Support
Representative.

Virtual Machines and the Virtual Infrastructure


The infrastructure that supports virtual machines consists of at least two software layers, virtualization and
management. In vSphere, ESX/ESXi provides the virtualization capabilities that aggregate and present the host
hardware to virtual machines as a normalized set of resources. Virtual machines can run on an isolated ESX/
ESXi host or on ESX/ESXi hosts that vCenter Server manages.

vCenter Server lets you pool and manage the resources of multiple hosts and lets you effectively monitor and
manage your physical and virtual infrastructure. You can manage resources for virtual machines, provision
virtual machines, schedule tasks, collect statistics logs, create templates, and more. vCenter Server also
provides VMware vMotion, VMware Storage vMotion, VMware Distributed Resources Management (DRS),
VMware HA, and Fault Tolerance. These services enable efficient and automated resource management and
high availability for virtual machines.

The VMware vSphere Client is the interface to vCenter Server, ESX/ESXi hosts, and virtual machines. With the
vSphere Client, you can connect remotely to vCenter Server or ESX/ESXi from any Windows system. The
vSphere Client is the primary interface for managing all aspects of the vSphere environment. It also provides
console access to virtual machines.

The vSphere Client presents the organizational hierarchy of managed objects in inventory views. Inventories
are the hierarchal structure used by vCenter Server or the host to organize managed objects. This hierarchy
includes all of the monitored objects in vCenter Server.

In the vCenter Server hierarchy, a datacenter is the primary container of ESX/ESXi hosts, folders, clusters,
resource pools, vApps, virtual machines, and so on. Datastores are virtual representations of underlying
physical storage resources in the datacenter. A datastore is the storage location (for example, a physical disk
or LUN on a RAID, or a SAN) for virtual machine files. Datastores hide the idiosyncrasies of the underlying
physical storage and present a uniform model for the storage resources required by virtual machines.

Virtual Machine Lifecycle


You create and deploy virtual machines into your datacenter in a variety of ways. You can create a single virtual
machine and install a guest operating system and VMware Tools in it. You can clone or create a template from
an existing virtual machine, convert physical systems to virtual machines, or deploy OVF templates.

The vSphere Client New Virtual Machine wizard and Virtual Machine Properties editor let you add, configure,
or remove most of the virtual machine's hardware, options, and resources. You monitor CPU, memory, disk,
network, and storage metrics using the performance charts in vSphere Client. VMware Snapshots let you
capture the entire state of the virtual machine, including the virtual machine memory, settings, and virtual
disks. You can roll back to the previous virtual machine state when needed.

12 VMware, Inc.
Chapter 1 Introduction to VMware vSphere Virtual Machines

With VMware vApp, you can manage multi-tiered applications. You use vCenter Update Manager to perform
orchestrated upgrades to upgrade the virtual hardware and VMware Tools of virtual machines in the inventory
at the same time.

When a virtual machine is no longer needed, you can remove it from the inventory without deleting it from
the datastore, or you can delete the virtual machine and all its files.

Virtual Machine Components


Virtual machines typically have an operating system, VMware Tools, and virtual resources and hardware that
you manage in much the same way as you would manage a physical computer.
You install a guest operating system on a virtual machine essentially the same way as you install an operating
system on a physical computer. You must have a CD/DVD-ROM or ISO image containing the installation files
from an operating system vendor.

VMware Tools is a suite of utilities that enhances the performance of the virtual machine's guest operating
system and improves management of the virtual machine. With VMware Tools, you have much more control
over the virtual machine interface.

All virtual machines have a hardware version. The hardware version indicates virtual hardware features
supported by the virtual machine, such as BIOS, number of virtual slots, maximum number of CPUs, maximum
memory configuration, and other characteristics typical to hardware. The hardware version of a virtual
machine is determined by the version of ESX/ESXi on which the virtual machine is created.

The hardware devices listed in the Virtual Machine Properties editor complete the virtual machine. Not all
devices are configurable. Some hardware devices are part of the virtual motherboard and appear in the
expanded device list of the Virtual Machine Properties editor, but you cannot modify or remove them. For a
complete list of hardware devices and their functions, see “Virtual Machine Hardware, Options, and Resources
Available to vSphere Virtual Machines,” on page 72.

Access to a virtual machine is controlled by the Sphere administrator. For detailed information about Privileges,
see the VMware vSphere Datacenter Administration Guide.

Virtual Machine Options and Resources


Each virtual device performs the same function for the virtual machine as hardware on a physical computer
does.

A virtual machine might be running in any of several locations, such as ESX/ESXi hosts, datacenters, clusters,
or resource pools. Many of the options and resources you configure have dependencies on and relationships
with these objects.

Every virtual machine has CPU, memory, and disk resources. CPU virtualization emphasizes performance
and runs directly on the virtual machine processor whenever possible. The underlying physical resources are
used whenever possible and the virtualization layer runs instructions only as needed to make virtual machines
operate as if they were running directly on a physical machine.

All recent operating systems provide support for virtual memory, allowing software to use more memory than
the machine physically has. Similarly, the ESX/ESXi hypervisor provides support for overcommitting virtual
machine memory, where the amount of guest memory configured for all virtual machines might be larger than
the amount of the host's physical memory.

You can add virtual disks and add more space to existing disks, even when the virtual machine is running.
You can also change the device node and allocate shares of disk bandwidth to the virtual machine.

VMware, Inc. 13
vSphere Virtual Machine Administration Guide

VMware virtual machines have the following options:

General Options View or modify the virtual machine name, check the location of the
configuration file and the working location of the virtual machine, or change
the guest operating system type.

vApp Options Enable or disable vApp functionality. When vApp is enabled, you can select
an IP allocation policy and other configurations particular to vApps.

VMware Tools Manage the power controls for the virtual machine and run VMware Tools
scripts. You can also upgrade VMware Tools during power cycling and
synchronize guest time with the host.

General Advanced Disable acceleration and enable logging, debugging, and statistics. Add
Options configuration parameters.

Power Management Manage guest power options. Suspend the virtual machine or leave the virtual
machine powered on when you put the guest operating system into standby.

CPUID Mask Hide or expose the NX/XD flag. Hiding the NX/XD flag increases vMotion
compatibility between hosts.

Memory/CPU Hotplug Disable or enable CPU and memory hotplug. You can disable Memory or CPU
hotplug if you do not want to add memory or processors accidentally while
the virtual machine is running.

Boot Options Set the boot delay when powering on virtual machines or to force BIOS setup
and configure failed boot recovery.

Fibre Channel NPIV Control virtual machine access to LUNs on a per-virtual machine basis. N-port
ID virtualization (NPIV) provides the ability to share a single physical Fibre
Channel HBA port among multiple virtual ports, each with unique identifiers.

Where to Go From Here


You must create, provision, and deploy your virtual machines before you can manage them.

To begin provisioning virtual machines, determine whether to create a single virtual machine and install an
operating system and VMware tools, work with templates and clones, deploy OVF templates, or convert
physical systems to virtual machines.

After you provision and deploy virtual machines into the vSphere infrastructure, you can configure and
manage them. Determine whether you want to configure existing virtual machines by modifying or adding
hardware or install or upgrade VMware Tools. You might need to manage multitiered applications with
VMware vApps or change virtual machine startup and shutdown settings, use snapshots, work with virtual
disks, or add, remove, or delete virtual machines from the inventory.

How to Provision Virtual Machines 2
VMware provides several methods to provision vSphere virtual machines. The optimal method for your
environment depends on factors such as the size and type of your infrastructure and the goals you are trying
to achieve.

Create a single virtual machine if no other virtual machines in your environment have the requirements you
are looking for, such as a particular operating system or hardware configuration. For example, you might need
a virtual machine that is configured only for testing purposes. You can also create a single virtual machine and
install an operating system on it, then use that virtual machine as a template to clone other virtual machines
from. See Chapter 3, “Creating a Virtual Machine,” on page 19.

Deploy and export virtual machines, virtual appliances, and vApps stored in Open Virtual Machine Format
(OVF) to use a preconfigured virtual machine. A virtual appliance is a prebuilt virtual machine that typically
has an operating system and other software already installed. You can deploy virtual machines from local file
systems, such as local disks (such as C:), removable media (such as CDs or USB keychain drives), and shared
network drives. See Chapter 5, “Deploying OVF Templates,” on page 53.

Create a template to deploy multiple virtual machines from. A template is a master copy of a virtual machine
that you can use to create and provision virtual machines. Templates can be a real time saver. If you have a
virtual machine that you want to clone frequently, make that virtual machine a template. See Chapter 4,
“Working with Templates and Clones,” on page 33.

Cloning a virtual machine can save time if you are deploying many similar virtual machines. You can create,
configure, and install software on a single virtual machine and clone it multiple times, rather than creating and
configuring each virtual machine individually. See Chapter 4, “Working with Templates and Clones,” on
page 33.

If you have a smaller IT environment, you can use VMware vCenter Guided Consolidation to convert physical
systems to virtual machines and import them into vSphere. See Chapter 6, “Converting Physical Systems to
Virtual Machines,” on page 57.

18 VMware, Inc.
Creating a Virtual Machine 3
Virtual machines are the key component in a virtual infrastructure. You can create a single virtual machine to
add to the vSphere inventory.

When you create a virtual machine, you associate it to a particular datacenter, host, cluster, or resource pool,
and a datastore. After you turn on the virtual machine, it consumes resources dynamically as the workload
increases, or it returns resources dynamically as the workload decreases.

Every virtual machine has virtual devices that provide the same function as physical hardware. A virtual
machine gets CPU and memory, access to storage, and network connectivity from the host it runs on.

vSphere Virtual Machine Administration Guide

Start the Virtual Machine Creation Process


You use the New Virtual Machine wizard to create a virtual machine to place in the vSphere inventory. You
open the wizard from the vSphere Client.

The selections you make in the New Virtual Machine wizard are not saved until you click Finish on the Ready
to Complete page. If you cancel the wizard without completing all tasks, you cannot resume the wizard where
you left off. You must start a new creation task.

Prerequisites

The vSphere Client must be running.

Procedure

1 Display the inventory objects in the vSphere Client by using the Host and Clusters view or the VM and
Templates view.

2 Right-click one of the following objects:


n Datacenter
n Host
n Cluster
n Resource Pool
n Virtual machine folder

3 Select File > New > Virtual Machine.

The New Virtual Machine wizard opens.

What to do next

Select a configuration path through the New Virtual Machine wizard.

Select a Configuration Path for the New Virtual Machine


The Typical path shortens the virtual machine creation process by skipping choices that you rarely need to
change from their defaults. The Custom path provides more flexibility and options.

Several relationships effect the information that you must provide during virtual machine creation. These
relationships include the inventory object on which you place the virtual machine, the customization path you
select, the datastore on which the virtual machine and its files reside, and the host or cluster on which it runs.

If you select a Typical configuration, the virtual machine hardware version defaults to that of the host on which
you place the virtual machine. If you select a Custom configuration, you can accept the default or select an
earlier hardware version. This is useful if maintaining compatibility with an earlier version of an ESX/ESXi
host is necessary.

For a Typical configuration, have the following information:


n Virtual machine name and inventory location.
n Location in which to place the virtual machine (cluster, host, resource pool).
n Datastore on which to store the virtual machines files.
n Guest operating system and version.
n Parameters for the virtual disk size and provisioning settings.

20 VMware, Inc.
Chapter 3 Creating a Virtual Machine

In addition to the information for a Typical configuration, for a Custom configuration, have the following
information:
n Virtual Machine version.
n Number of CPUs and memory size.
n Number of NICs, network to connect to, and network adapter types.
n SCSI controller type.
n Disk type (new disk, existing disk, RDM, or no disk).

Procedure

1 On the Configuration page of the New Virtual Machine wizard, select a path for creating the virtual
machine.
n Typical
n Custom

2 Click Next.

The Name and Location page appears.

What to do next

Select a name and location for the virtual machine.

Enter a Name and Location for the Virtual Machine


The name you enter is used as the virtual machine’s base name in the inventory. It is also used as the name of
the virtual machine’s files.

The name can be up to 80 characters long. If you are connected to vCenter Server and have folders in your
inventory, names must be unique within the folder. Names are not case-sensitive, so the name my_vm is
identical to My_Vm.

Prerequisites

Verify that you have an appropriate naming strategy in place.

Procedure

1 On the Name and Location page of the New Virtual Machine wizard, type a name.

2 Select a folder or the root of the datacenter.

3 Click Next.

The Host / Cluster or the Resource Pool page opens.

Select a Host or Cluster


You can place the virtual machine on a standalone host or in a cluster.

A cluster is a collection of ESX/ESXi hosts and associated virtual machines with shared resources and a shared
management interface. Grouping hosts into clusters allows you to enable many optional features that enhance
the availability and flexibility of your infrastructure.

VMware, Inc. 21
vSphere Virtual Machine Administration Guide

Procedure

1 On the Host / Cluster page of the New Virtual Machine wizard, select the host or cluster where you want
to run the virtual machine.

2 Click Next.

If resource pools are configured on the host, the Resource Pool page opens. Otherwise, the Datastore page
opens.

What to do next

Select a resource pool or a datastore on which to run the virtual machine.

Select a Resource Pool


Resource pools let you manage your computing resources within a host or cluster by setting them up in a
meaningful hierarchy. Virtual machines and child resource pools share the resources of the parent resource
pool.

The Resource Pool page appears only when resource pools are configured on the host.

Procedure

1 On the Resource Pool page of the New Virtual Machine wizard, navigate to the resource pool where you
want to run the virtual machine.

2 Select the resource pool and click Next.

The virtual machine is placed in the resource pool you selected.

What to do next

Select a datastore in which to store the virtual machine files.

Select a Datastore
Datastores are logical containers that hide specifics of each storage device and provide a uniform model for
storing virtual machine files. You can use datastores to store ISO images, virtual machine templates, and floppy
images.

You can select from datastores already configured on the destination host or cluster.

Procedure

1 On the Datastore page of the New Virtual Machine wizard, select a datastore large enough to hold the
virtual machine and all of its virtual disk files.

2 Click Next.

If you selected a Typical configuration path, the Guest Operating System page appears. If you selected a
Custom configuration path, the Virtual Machine Version page appears.

22 VMware, Inc.
Chapter 3 Creating a Virtual Machine

Select a Virtual Machine Version


If the host or cluster where you place the virtual machine supports more than one VMware virtual machine
version, you can select a version for the virtual machine.

Procedure

1 On the Virtual Machine Version page of the New Virtual Machine wizard, select a version for the virtual
machine.

Option Description
Virtual machine version 7 Compatible with ESX 4.0 and greater hosts. It provides greater virtual
machine functionality and is recommended for virtual machines that do not
need to migrate to ESX 3.x hosts.
Virtual machine version 4 Compatible with ESX 3.0 and greater hosts. VMware recommends this
option for virtual machines that must run on ESX 3.x hosts and for virtual
machines that must share virtual hard disks with other version 4 virtual
machines.

2 Click Next.

The Guest Operating System page opens.

What to do next

Select a guest operating system for the virtual machine.

Select an Operating System


The guest operating system that you select affects the supported devices and number of virtual CPUs available
to the virtual machine.

The New Virtual Machine wizard does not install the guest operating system. The wizard uses this information
to select appropriate default values, such as the amount of memory needed.

Procedure

1 On the Guest Operating System page of the New Virtual Machine wizard, select an operating system
family.
n Microsoft Windows
n Linux
n Novell NetWare
n Solaris
n Other

2 Select an operating system and version from the drop-down menu and click Next.

If you selected a Novell NetWare guest operating system, the Memory page opens. For all other selections,
the CPUs page opens.

What to do next

You can configure CPUs or memory for the virtual machine.

VMware, Inc. 23
vSphere Virtual Machine Administration Guide

Select the Number of Virtual Processors


You can configure a virtual machine to have up to eight virtual processors or CPUs. The number of licensed
CPUs on the host and the number of processors supported by the guest operating system limit the number of
virtual processors that you can create.

VMware Virtual SMP is required to power on multiprocessor virtual machines. The Virtual CPUs page appears
for multiprocessor hosts.

Procedure

1 On the CPUs page of the New Virtual Machine wizard, select the number of virtual processors from the
drop-down menu.

2 Click Next.

The Memory page opens.

What to do next

Select the Memory for the virtual machine.

Configure Virtual Memory


The amount of memory you allocate for a virtual machine is the amount of memory the guest operating system
sees.

Minimum memory size is 4MB. Maximum memory size depends on the host. The memory size must be a
multiple of 4MB. The maximum for best performance represents the threshold above which the host’s physical
memory is insufficient to run the virtual machine at full speed. This value fluctuates as conditions on the host
change, for example, as virtual machines are turned on or off.

Procedure

1 On the Memory page of the New Virtual Machine wizard, select a size in megabytes or gigabytes for the
virtual memory.

You can use the slider or select the number by using the up and down arrows.

2 Click Next.

The Network page opens.

What to do next

Select network adapters for the virtual machine.

Configure Networks
You configure network settings so that the virtual machine can communicate with other hosts and virtual
machines.

CAUTION Because virtual machines share their physical network hardware with the host, the accidental or
malicious bridging of two networks by a virtual machine can occur. Spanning Tree protocol cannot protect
against these occurrences.

Although hardware version 7 virtual machines support up to ten virtual NICs, during virtual machine creation
you can select only four NICs. You can add more virtual NICs by selecting Edit the virtual machine settings
before completion on the Ready to Complete page of the wizard, or by editing the virtual machine after it is
created.

About VMware Paravirtual SCSI Adapters


Paravirtual SCSI (PVSCSI) adapters are high performance storage adapters that can result in greater
throughput and lower CPU utilization. PVSCSI adapters are best suited for high performance storage
environments.

PVSCSI adapters are available for virtual machines running hardware version 7 and later. They are supported
on the following guest operating systems:
n Windows Server 2008 R2 (64bit)
n Windows Server 2008 (32bit and 64bit)
n Windows Server 2003 (32bit and 64bit)
n Windows XP (32bit and 64bit)
n Windows Vista (32bit and 64bit)
n Windows 7 (32bit and 64bit)
n Red Hat Linux 5 (32bit and 64bit)

PVSCSI adapters have the following limitations:


n Disks on PVSCSI adapters might not experience performance gains if they have snapshots or if memory
on the ESX host is over committed.
n If you upgrade from RHEL 5 to an unsupported kernel, you might not be able to access data on the disks
attached to a PVSCSI adapter. To regain access to such disks:

a Upgrade the guest kernel but do not restart the guest.

b Run the VMware Tools configuration with the kernel-version parameter and pass the kernel version
within the guest:
vmware-config-tools.pk --kernel-version kernel_version

Run name -r to determine the version of the running kernel.

c Restart the guest.


n MSCS clusters are not supported.
n PVSCSI adapters do not support boot disks (the disk that contains the system software) on Red Hat Linux
5 virtual machines. Attach the boot disk to the virtual machine by using any of the other supported adapter
types.

VMware, Inc. 25
vSphere Virtual Machine Administration Guide

Select a SCSI Controller


To access virtual disks, a virtual machine uses virtual SCSI controllers. Each virtual disk that a virtual machine
can access through one of the virtual SCSI controllers resides in the VMware Virtual Machine File System
(VMFS) datastore, NFS-based datastore, or on a raw disk. The choice of SCSI adapter does not affect whether
your virtual disk is an IDE or SCSI disk.

The wizard preselects the correct default controller based on the guest operation system you selected on the
Guest Operating System page.
LSI Logic SAS and VMware Paravirtual controllers are available only for virtual machines with hardware
version 7 or later.

Disks with snapshots might not experience performance gains when used on LSI Logic SAS and LSI Logic
Parallel adapters.

Procedure

1 On the SCSI Controller page of the New Virtual Machine wizard, accept the default or select a SCSI
controller type.

2 Click Next.

The Select a Disk page opens.

What to do next

Select a disk on which to store the guest operating system files and data.

Selecting a Virtual Disk Type


You can create a virtual disk, use an existing virtual disk, or create Raw Device Mappings (RDMs), which give
your virtual disk direct access to SAN. A virtual disk comprises one or more files on the file system that appear
as a single hard disk to the guest operating system. These disks are portable among hosts.

You can add virtual disks to the virtual machine while you create or after you create the virtual machine. To
add disks later, select the Do Not Create Disk option.

You can select from the following options:


n Create a Virtual Disk on page 27
When you create a virtual disk, you can specify disk properties such as size, format, clustering features,
and more.
n Use an Existing Virtual Disk on page 28
You can use an existing disk that is configured with an operating system or other virtual machine data.
This choice allows you to freely move the virtual hard drive from virtual machine to virtual machine.
n Create Raw Device Mappings on page 28
For virtual machines running on an ESX/ESXi host, instead of storing virtual machine data in a virtual
disk file, you can store the data directly on a SAN LUN. This is useful if you are running applications in
your virtual machines that must know the physical characteristics of the storage device. Additionally,
mapping a SAN LUN allows you to use existing SAN commands to manage storage for the disk.

26 VMware, Inc.
Chapter 3 Creating a Virtual Machine

Create a Virtual Disk


When you create a virtual disk, you can specify disk properties such as size, format, clustering features, and
more.

Using the default thick virtual disk format does not zero out or eliminate the possibility of recovering deleted
files or restoring old data that might be present on this allocated space. It is not possible to convert a thick disk
to a thin disk.

In most cases, you can accept the default device node. For a hard disk, a nondefault device node is useful to
control the boot order or to have different SCSI controller types. For example, you might want to boot off an
LSI Logic controller and share a data disk with another virtual machine using a BusLogic controller with bus
sharing turned on.

Procedure

1 On the Create a Disk page of the New Virtual Machine wizard, select the disk size in Megabytes, Gigabytes,
or Terabytes.

You can increase the disk size later or add disks in the Virtual Machine Properties dialog box.

Use an Existing Virtual Disk


You can use an existing disk that is configured with an operating system or other virtual machine data. This
choice allows you to freely move the virtual hard drive from virtual machine to virtual machine.

In most cases, you can accept the default device node. For a hard disk, a nondefault device node is useful to
control the boot order or to have different SCSI controller types. For example, you might want to boot off an
LSI Logic controller and share a data disk with another virtual machine using a BusLogic controller with bus
sharing turned on.

Create Raw Device Mappings


For virtual machines running on an ESX/ESXi host, instead of storing virtual machine data in a virtual disk
file, you can store the data directly on a SAN LUN. This is useful if you are running applications in your virtual
machines that must know the physical characteristics of the storage device. Additionally, mapping a SAN LUN
allows you to use existing SAN commands to manage storage for the disk.

When you map a LUN to a VMFS volume, vCenter Server creates a Raw Device Mapping (RDM) file that
points to the raw LUN. Encapsulating disk information in a file allows vCenter Server to lock the LUN so that
only one virtual machine can write to it at a time. For details about RDM, see the ESX Configuration Guide or
ESXi Configuration Guide.

The RDM file has a .vmdk extension, but the file contains only disk information that describes the mapping to
the LUN on the ESX/ESXi host. The actual data is stored on the LUN.

You can change existing settings, configure resources, add hardware, and more.

You can configure additional virtual machine settings before or after completing the wizard.

VMware, Inc. 29
vSphere Virtual Machine Administration Guide

Procedure

1 On the Ready to Complete page of the New Virtual Machine wizard, review the configuration settings for
the virtual machine.

2 (Optional) Select Edit the virtual machine settings before completion and click Continue.

The Virtual Machine Properties editor opens. After you complete your changes and click Finish, both the
Virtual Machine Properties editor and the New Virtual Machine wizard close. You cannot go back to
review the wizard settings unless you click Cancel.

3 (Optional) Click Cancel to go back and review the wizard settings.


4 Click Finish to complete the creation task and close the wizard.

The virtual machine appears in the vSphere Client Inventory view.

What to do next

Before you can use the new virtual machine, you must partition and format the virtual drive, install a guest
operating system, and install VMware Tools. Typically, the operating system’s installation program handles
partitioning and formatting the virtual drive.

Installing a Guest Operating System


A virtual machine is not complete until you install the guest operating system and VMware Tools. Installing
a guest operating system in your virtual machine is essentially the same as installing it in a physical computer.

The basic steps for a typical operating system are described in this section. See the Guest Operating System
Installation Guide for more information about individual guest operating systems.

Using PXE with Virtual Machines


You can start a virtual machine from a network device and remotely install a guest operating system using a
Preboot Execution Environment (PXE).

PXE booting is supported for Guest Operating Systems that are listed in the VMware Guest Operating System
Compatibility list and whose operating system vendor supports PXE booting of the operating system.

The virtual machine must meet the following requirements:


n Have a virtual disk without operating system software and with enough free disk space to store the
intended system software.
n Have a network adapter connected to the network where the PXE server resides.

For details about guest operating system installation, see the Guest Operating System Installation Guide.

Install a Guest Operating System from Media


You can install a guest operating system from a CD-ROM or from an ISO image. Installing from an ISO image
is typically faster and more convenient than a CD-ROM installation.

It might be necessary to change the boot order in the virtual machine’s BIOS settings. However, sometimes a
virtual machine’s boot sequence progresses too quickly for a user to open a console to the virtual machine and
enter BIOS setup. If this happens, select Boot Options on the Options tab of the Virtual Machine Properties
dialog box, and select The next time the virtual machine boots, force entry into the BIOS setup screen. The
virtual machine enters the BIOS setup the next time it starts.

Working with Templates and Clones 4
A clone is a copy of a virtual machine. A template is a master copy of a virtual machine that can be used to
create many clones.

When you clone a virtual machine, you create a copy of the entire virtual machine, including its settings, any
configured virtual devices, installed software, and other contents of the virtual machine's disks. You also have
the option to use guest operating system customization to change some of the properties of the clone, such as
the computer name and networking settings.

Cloning a virtual machine can save time if you are deploying many similar virtual machines. You can create,
configure, and install software on a single virtual machine, and then clone it multiple times, rather than creating
and configuring each virtual machine individually.

If you create a virtual machine that you want to clone frequently, make that virtual machine a template. A
template is a master copy of a virtual machine that can be used to create and provision virtual machines.
Templates cannot be powered on or edited, and are more difficult to alter than ordinary virtual machine. A
template offers a more secure way of preserving a virtual machine configuration that you want to deploy many
times.

When you clone a virtual machine or deploy a virtual machine from a template, the resulting cloned virtual
machine is independent of the original virtual machine or template. Changes to the original virtual machine
or template are not reflected in the cloned virtual machine, and changes to the cloned virtual machine are not
reflected in the original virtual machine or template.

Clone a Virtual Machine


Cloning a virtual machine creates a duplicate of the virtual machine with the same configuration and installed
software as the original.

Optionally, you can customize the guest operating system of the clone to change the virtual machine name,
network settings, and other properties. This prevents conflicts that can occur if a virtual machine and a clone
with identical guest operating system settings are deployed simultaneously.

Prerequisites
n You must be connected to vCenter Server in order to clone a virtual machine. You cannot clone virtual
machines if you connect directly to an ESX/ESXi host.
n To customize the guest operating system of the virtual machine, check that your guest operating system
meets the requirements for customization. See “Guest Operating System Customization Requirements,”
on page 42.
n To use a customization specification, you must first create or import the customization specification.
n To use a custom script to generate the host name or IP address for the new virtual machine, configure the
script. See “Configure a Script to Generate Computer Names and IP Addresses During Guest Operating
System Customization,” on page 43.

Customizing Guest Operating Systems


When you clone a virtual machine or deploy a virtual machine from a template, you can customize the guest
operating system of the virtual machine to change properties such as the computer name, network settings,
and license settings.

Customizing guest operating systems can help prevent conflicts that can result if virtual machines with
identical settings are deployed, such as conflicts due to duplicate computer names.
You can specify the customization settings by choosing to launch the Guest Customization wizard during the
cloning or deployment process. Alternatively, you can create customization specifications, which are
customization settings stored in the vCenter Server database. During the cloning or deployment process, you
can select a customization specification to apply to the new virtual machine.

Use the Customization Specification Manager to manage customization specifications you create with the
Guest Customization wizard.

Guest Operating System Customization Requirements


Guest operating system customization is supported only if a number of requirements are met.

VMware Tools Requirements


The most current version of VMware Tools must be installed on the virtual machine or template to customize
the guest operating system during cloning or deployment.

42 VMware, Inc.
Chapter 4 Working with Templates and Clones

Virtual Disk Requirements


The guest operating system being customized must be installed on a disk attached as SCSI node 0:0 in the
virtual machine configuration.

Virtual machines that reside on hosts running ESX Server 3.0.x or earlier have additional disk requirements:
n On a Windows guest operating system, the active partition (the partition containing boot.ini) and the
system partition (the partition containing the system directory, for example, \WINNT or WINDOWS) must be
on the same virtual disk. The active partition and the system partition do not need to be the same partition.
n On a Linux guest operating system, the virtual disk containing the system partition (the partition
containing the /etc directory) must reside on the SCSI 0:0 node.

Windows Requirements
Customization of Windows guest operating systems requires the following conditions:
n Microsoft Sysprep tools must be installed on the vCenter Server system. See Appendix A, “Installing the
Microsoft Sysprep Tools,” on page 153.
n The ESX/ESXi host that the virtual machine is running on must be 3.5 or later.

Guest operating system customization is supported on multiple Windows operating systems. To verify
customization support for Windows operating systems and compatible ESX/ESXi hosts, see VMware vSphere
Compatibility Matrixes.

Linux Requirements
Customization of Linux guest operating systems requires the following conditions:
n Perl must be installed in the Linux guest operating system.
n The clone or template must have a root volume formatted with an ext2, ext3, or ReiserFS file system.

Guest operating system customization is supported on multiple Linux distributions. To verify customization
support for Linux distributions and compatible ESX/ESXi hosts, see VMware vSphere Compatibility Matrixes.

Configure a Script to Generate Computer Names and IP Addresses During Guest


Operating System Customization
As an alternative to specifying the computer name or IP addresses for virtual NICs during customization, you
can create a script to generate these items.

The script is executed by the Windows command-line script host (cscript.exe). The script can be written in
any compatible scripting language, including JScript or VBScript. See the Microsoft documentation for
cscript.exe for more information on writing scripts.

Procedure

1 Create the script and save it on the vCenter Server system's local disk.

2 In the vSphere Client connected to vCenter Server, select Administration > vCenter Server Settings.

3 Select Advanced Settings.

Managing Customization Specifications


Customization specifications are XML files that contain guest operating system settings for virtual machines.
You create customization specifications with the Guest Customization wizard, and manage specifications
using the Customization Specification Manager.

vCenter Server saves the customized configuration parameters in the vCenter Server database. If the
customization settings are saved, the administrator, and domain administrator, passwords are stored in
encrypted format in the database. Because the certificate used to encrypt the passwords is unique to each
vCenter Server system, reinstalling vCenter Server, or attaching a new instance of the server the database,
invalidates the encrypted passwords. The passwords must be re-entered before they can be used.

Deploying OVF Templates 5
The VMware vSphere Client (vSphere Client) allows you to deploy and export virtual machines, virtual
appliances, and vApps stored in Open Virtual Machine Format (OVF). An appliance is a pre-configured virtual
machine that typically includes a preinstalled guest operating system and other software.

Deploying an OVF template allows you to add pre-configured virtual machines to your vCenter Server or ESX/
ESXi inventory. Deploying an OVF template is similar to deploying a virtual machine from a template.
However, you can deploy an OVF template from any local file system accessible from the vSphere Client
machine, or from a remote web server. The local file systems can include local disks (such as C:), removable
media (such as CDs or USB keychain drives), and shared network drives.

Exporting OVF templates allows you to create virtual appliances that can be imported by other users. You can
use the export function to distribute pre-installed software as a virtual appliance, or as a means of distributing
template virtual machines to users, including users who cannot directly access and use the templates in your
vCenter Server inventory.

This chapter includes the following topics:


n “About OVF,” on page 53
n “Deploy an OVF Template,” on page 54
n “Browse VMware Virtual Appliance Marketplace,” on page 55
n “Export an OVF Template,” on page 55

About OVF
OVF is a file format that allows for exchange of virtual appliances across products and platforms.

The OVF format offers the following advantages:


n OVF files are compressed, allowing for faster downloads.
n The vSphere Client validates an OVF file before importing it, and ensures that it is compatible with the
intended destination server. If the appliance is incompatible with the selected host, it cannot be imported
and an error message appears.
n OVF can encapsulate multi-tiered applications and more than one virtual machine.

VMware, Inc. 53
vSphere Virtual Machine Administration Guide

Deploy an OVF Template


You can deploy an OVF template from a local file system accessible to the vSphere Client machine, or from a
web URL.

Converting Physical Systems to
Virtual Machines 6
VMware vCenter Guided Consolidation, recommended for smaller IT environments, enables you to convert
physical systems to virtual machines and import them into vSphere. Use the consolidation feature to start
transitioning your physical datacenter to a virtual one, or to further consolidate your physical datacenter as it
grows.

Consolidating your datacenter involves the following process:

Find You search for and select the physical systems in your datacenter that you want
analyzed.

Analyze Selected physical systems are analyzed and performance data on each selected
system is collected. Generally, the longer the duration of the analysis phase,
the higher the confidence in the vCenter Server’s recommendations.

Consolidate Performance data is compared to the resources available on the virtual machine
host systems. The selected physical systems are converted to virtual machines
and imported into vCenter Server on the recommended hosts where they are
managed along with other components of your virtual environment.

Access the Guided Consolidation feature by clicking the Consolidation button.

vSphere Virtual Machine Administration Guide

Consolidation First Time Use


The first time you use the Consolidation feature, VMware recommends that you specify consolidation settings.
These settings include default system credentials and active domains.

Default system credentials enable you to store a set of credentials so that you do not have to enter them each
time you add systems for analysis. You can override default credentials when necessary.

Active domains enable you to register domains with the Consolidation feature. Active domains are scanned
daily so that newly added systems are readily available.

Consolidation Prerequisites
Guided Consolidation requires that at least one host is managed through vSphere. It also requires that you
provide credentials to the target physical systems.

Guided Consolidation can convert systems that are configured to any locale. Before you use the feature, ensure
that the following prerequisites are met:

Guided Consolidation Server Host Requirements


Guided Consolidation server must be installed on a host that meets the following system requirements:
n Located within the company's network and have access to target systems for performance data collection.
n The Guided Consolidation host must have a name that can be resolved from any machine on the network

About Consolidation Services


Guided Consolidation can be installed together with vCenter Server, or can be installed on a separate host. For
best performance, install Guided Consolidation on a separate host.

Guided Consolidation include the following services:

vCenter Collector Discovers domains and systems within domains. Collects performance data on
Service those systems.

vCenter Provider Helper service to vCenter Collector Service. Communicates with target systems
Service and passes the data back to vCenter Collector Service.

vCenter Guided Coordinates all communication among Guided Consolidation components.


Consolidation Saves the performance data collected by the vCenter Collector Service.
Analyzes the data and generates placement recommendations. Also
communicates with vCenter Server to perform conversion. Runs inside a
generic servlet container labeled VMware vCenter Management
Webservices. The services of other vCenter features and extensions might also
be present inside that servlet container.

Configuring Consolidation Settings


It is recommended that you specify Consolidation settings before using the feature. Consolidation settings are
located in the Configuration tab of the Guided Consolidation section of the vSphere Client.

The Configuration tab displays name, location, and health of Consolidation services. It also enables you to
configure the following settings:

Default system Used by Guided Consolidation to access target physical systems. If necessary,
credentials the default credentials can be overridden.

Active Domains Guided Consolidation automatically scans active domains and caches
information about the systems in them. This information is updated daily. If
you intend to add systems for analysis by selecting them from a domain, you
must specify the domain as Active.

Specify Default Credentials


Default credentials are used to access systems selected for analysis when no other administrator credentials
are specified.

Procedure

1 Click Change in the Default System Credentials area of the Configuration tab.

2 Enter a domain-qualified user name and password.

For example: DOMAIN\username.

3 Confirm the password and click OK.

VMware, Inc. 61
vSphere Virtual Machine Administration Guide

Specify Active Domains


Specifying a domain as Active populates the Add to Analysis dialog box with a list of systems on that domain.
That information is updated daily as long as the domain remains active.

VMware recommends that you leave domains where new systems are frequently added as Active and that
you remove domains that do not frequently change after their information has been cached. Because scanning
active domains is resource intensive, VMware also recommends that no more than 50 domains are
simultaneously active.

NOTE In some cases it can take the system several hours to collect a domain's containment information.

Procedure

1 From the vSphere Client Home page, select Guided Consolidation > Configuration.

2 Click Add in the Active Domains section.

3 Select the domains you want to make active.

4 Click OK.

Find and Analyze Physical Systems


The Add to Analysis dialog box enables you to find systems in your environment and add them for analysis,
to manually search for physical systems, or to select systems from the list of systems found in active domains.
You can select systems and add them for analysis.

You can add systems manually by entering a computer name, IP address or range of IP addresses, or file name.
Alternatively, you can select a domain - it must be active - and select systems found within that domain. You
can analyze up to 100 systems simultaneously.

NOTE After adding a system for analysis, it can take up to one hour before the status of the newly added
system changes from Collecting System Information to Analyzing.

Procedure

1 In the Analysis tab, click Add to Analysis.

2 Specify the systems you want to analyze.

Option Description
Manually specify the computers Provide computer names, IP addresses, a range of IP addresses, or path to a
file that contains the computer names or IP addresses of the systems you
want according to the following rules:
n Separate multiple computer names, or IP address, with a comma.
n Multiple IP ranges are not permitted.
n If you chose to use a file, each computer name or IP address must be on
a separate line in the file. The file must be accessible to the vSphere Client.
Select the computers by domains Select the systems you want to analyze.

3 Click Add to Analysis.

4 Select whether you want to use the configured default credentials, or whether you want to supply a
different set of credentials.

If you chose to override the default credentials, ensure that you enter a domain-qualified user name (for
example, DOMAIN\username) and password.

5 Click OK.

Chapter 6 Converting Physical Systems to Virtual Machines

Viewing Analysis Results


Analysis results are displayed in the Analysis tab.

When analysis is complete, the following information appears:


n Physical Computer – Displays the host name of the physical system being analyzed or imported.
n CPU Info – Displays the number of CPUs and their clock speed.
n Memory Info – Displays the amount of RAM on the system.
n Status – Displays the progress of the analysis.
n Confidence – Indicates the degree to which vCenter Server is able to gather performance data about the
system and how good a candidate the system is based on the available data.
n CPU Usage – Displays the system’s average CPU usage over time.
n Memory Usage – Displays the system’s average memory usage over time.

About the Confidence Metric


One important metric displayed in the Analysis tab is the Confidence metric. During the analysis phase,
performance data about each selected system is collected. This data is used to find a host with resources that
match the collected data to determine a recommendation for each candidate.

The recommendation indicates how well suited, based on the collected data, a candidate is to a particular
virtual machine host system. Confidence refers to the reliability of the recommendation and it is a function of
the duration of the analysis. Recommendations based on longer periods of analysis – and therefore more
performance data – receive a higher level of confidence.

NOTE After 24 hours of analysis, vCenter Server indicates a high level of confidence in its recommendations.
However, this can be misleading if a system’s workload varies significantly over weeks or months. To ensure
a high level of confidence in a recommendation, allow the duration of the analysis phase to encompass an
amount of time that includes representative peaks and troughs in the systems’ workload. Analysis can run up
to one month.

Converting Physical Systems to Virtual Machines


You can convert systems using auto-generated recommendations, or you can manually specify conversion
parameters.

About Disk Resizing


During the conversion process, physical disks are typically resized to conserve space on the datastore while
providing room for growth on the resultant virtual disk.

The following formula is used to resize converted disks:


amount of space used on physical disk * 1.25 = resultant virtual disk size

Virtual disks are set to a size of 4GB or larger.

VMware, Inc. 63
vSphere Virtual Machine Administration Guide

Convert Systems Manually


You can convert systems manually if you want to specify values other than the default values for the resultant
virtual machine's properties.

The option to convert systems manually is available only if the vCenter Converter client plug-in is installed
and enabled on your vSphere Client. You can verify whether vCenter Converter client is installed and enabled
through the Plug-in Manager.

Procedure

1 In the Analysis tab, right-click on a system and select Convert to Virtual Machine > Manually.

2 Complete the wizard to manually specify virtual machine properties.

Convert Systems Using Recommendations


Guided Consolidation recommendations are based on collected performance data and the capacity of available
hosts.

Procedure

1 In the Analysis tab, select the systems you want to consolidate and click Plan Consolidation.

2 Select a system.

3 (Optional) Change the name displayed in the Physical Computer column by double-clicking it and
entering a new name.

Your entry will be used as the name for the resultant virtual machine.

4 (Optional) Change destinations, if alternative destinations are available, by clicking in the Destinations
column and selecting a destination from the drop-down menu.

The number of stars displayed in the Destination Rating column indicate the degree to which the host
system can comfortably accommodate the estimated resource needs of the resultant virtual machine.

5 Click Consolidate.

A conversion task is instantiated.

What to do next

You can view task progress in the Recent Tasks pane. You view additional information about the task in the
Tasks tab.

Viewing Consolidation Tasks


A task is created for each system being converted.

Recent tasks are displayed in the Recent Tasks pane. The Tasks tab lists all consolidation tasks. You can view
detailed information about a task by selecting it. Information about events related to the selected task are
displayed in the Task Details pane.

You can filter the list of tasks by entering criteria in the search field and selecting any combination of the

Troubleshooting Consolidation
The topics in this section contain information about identifying and solving problems with Guided
Consolidation.

Negative Impact on vCenter Server Performance


Analyzing many systems simultaneously can impact vCenter Server performance.

Problem
Although up to 100 systems can be simultaneously analyzed, you might notice performance issues on the
vCenter Server that are due to running Guided Consolidation.

Cause
Analysis is resource intensive and can negatively impact vCenter Server performance.

Solution
Reduce the number of systems that are being analyzed. If necessary, you can either disable Guided
Consolidation or uninstall the Guided Consolidation Service. If you disable Guided Consolidation, collected
data is preserved and no further data is collected. If you uninstall the Guided Consolidation Service, the data
that has been collected will no longer be usable.

Windows Systems Not Discovered


Guided Consolidation does not discover some Windows systems.

Problem
Windows systems that match all of the following conditions will not be discovered by Guided Consolidation
and will not be listed as candidates for analysis:
n The system is not listed in Microsoft Windows Network. The following commands do not list the system:
NET VIEW
NET VIEW /DOMAIN:the Workgroup or Domain the system belongs to

n The system is listed in Active Directory but does not have the operatingSystem attribute defined. This can
happen if the system never synchronizes with the Active Directory to which it belongs or was improperly
configured.

Solution
n Enable the Computer Browser service on the machine where Guided Consolidation is installed and on
the systems that are not discovered.
n Ensure that the Log On As credentials for VMware vCenter Collector Provider Service met the
prerequisites as mentioned in “Consolidation Prerequisites,” on page 58.
n Manually enter the static IP address of the target system.

VMware, Inc. 65
vSphere Virtual Machine Administration Guide

Windows Operating Systems Prevent Guided Consolidation from Collecting


Performance Data
The default settings for some configurations of Windows XP, Windows Vista, and Windows Server 2008
prevent Guided Consolidation from collecting performance data against systems with those operating systems.

Problem
n The system is not listed in Microsoft Windows Network. The following commands do not list the system:
NET VIEW
NET VIEW /DOMAIN:the Workgroup or Domain the system belongs to

n The system is listed in Active Directory but does not have the operatingSystem attribute defined. This can
happen if the system never synchronizes with the Active Directory to which it belongs or was improperly
configured.

Solution
1 Set the Guided Consolidation target systems' Network access: Sharing and security model for local
accounts option to Classic - local users authenticate as themselves

2 Select Start > Run.

3 Run either gpedit.msc or secpol.msc

4 In the left pane, select one of the following depending on which command you ran in the previous step:

a (gpedit.msc) Local Computer Policy > Computer Configuration > Windows Settings > Security
Settings > Local Policies > Security Options

b (secpol.msc) Security Settings > Local Policies > Security Options > Double-click on Network
access: Sharing and security model for local accounts.

c Double-click on Network access: Sharing and security model for local accounts. Ensure that Classic
- local users authenticate as themselves is selected.

5 Ensure the changed settings are applied.


n Restart VMware vCenter Collector Provider Service.
n Run gpupdate /force.
n Reboot the Guided Consolidation host system.

Available Domains List Remains Empty


Analyzing many systems simultaneously can impact vCenter Server performance.

Problem
The list of available domains remains empty for Guided Consolidation installed on Windows Server 2008 and
Windows Vista.

Cause
Some configurations of Windows Vista and Windows Server 2008 prevent Guided Consolidation from
discovering LAN Manager Workgroups. The Link-layer discovery protocol (LLDP), introduced in Windows
2008 Server, is not backward compatible with LAN Manager-based protocols and can not discover machines
with earlier operating systems if those systems do not have the appropriate drivers installed. Additionally,
Guided Consolidation does not use LLDP to perform discovery and will not find systems that can only be
discovered through that protocol, or when the Computer Browser Windows Service is not running.

66 VMware, Inc.
Chapter 6 Converting Physical Systems to Virtual Machines

Solution
Ensure that the Computer Browser Windows Service is enabled on the Windows Vista or Windows Server
2008 system where Guided Consolidation is installed and that it is also enabled on all systems to be discovered.
Alternatively, manually enter the static IP address of the system to be analyzed.

Guided Consolidation Erroneously Reports Analysis Disabled


Under some conditions, temporary network errors can disable analysis on multiple systems.

Problem
Temporary network errors can sometimes cause Guided Consolidation to stop analysis on one or more systems,
even when the systems are reachable.

Solution
Right-click on the affected systems and select Resume Analysis.

Disable Guided Consolidation


You can disable Guided Consolidation.

Procedure

1 On the Guided Consolidation host system, open the Services control panel.

2 Stop theVMware vCenter Management Webservices (applicable when Guided Consolidation and
vCenter Server are not collocated), the VMware Collector for vCenter, and the VMware Provider for
vCenter services.

Uninstall Guided Consolidation


Uninstall Guided Consolidation to completely remove the feature. All collected data is also removed.

Procedure

1 Open the Add or Remove Programs control panel.

2 Remove vCenter Guided Consolidation for vCenter Server.

All vCenter Guided Consolidation services are removed.

CAUTION Do not uninstall the vCenter Collector Service alone. Doing so prevents Guided Consolidation from
operating and will require that you perform a clean installation of Guided Consolidation, which will delete
existing Guided Consolidation data.

Virtual Machine Hardware, Options, and Resources Available to


vSphere Virtual Machines
VMware provides a wide range of devices, options, and resources that you can configure or add to your virtual
machine.

Virtual Machine Hardware


Table 7-1 lists the hardware devices available to a virtual machine.

Not all hardware devices are available to every virtual machine. The host the virtual machine runs on and the
guest operating system must support devices that you add or configurations that you make. You can add or
configure some virtual machine hardware, such as USB device passthrough from an ESX/ESXi host to a virtual
machine, only if the virtual machine uses hardware version 7 or later. The PCI, SIO, and PS2 controllers are
virtual hardware devices that are part of the virtual motherboard, but cannot be configured or removed.

Table 7-1. Virtual Machine Hardware


Hardware Device Description

CPU You can configure a virtual machine that runs on an ESX/ESXi host to have one
or more virtual processors. A Virtual machine cannot have more virtual CPUs
than the actual number of logical CPUs on the host. You can change the number
of CPUs allocated to a virtual machine and configure advanced CPU features, such
as the CPU Identification Mask and hyperthreaded core sharing.

DVD/CD-ROM Drive Installed by default when you create a new vSPhere virtual machine. You can
configure DVD/CD-ROM devices to connect to client devices, host devices, or
Datastore ISO files. You can add, remove, or configure DVD/CD-ROM devices.

Floppy Drive Installed by default when you create a new vSPhere virtual machine. You can
connect to a floppy drive located on the ESX/ESXi host, a floppy (.flp) image, or
the floppy drive on your local system. You can add, remove, or configure floppy
devices.

Hard Disk Stores the virtual machine's operating system, program files, and other data
associated with its activities. A virtual disk is a large physical file, or a set of files,
that can be copied, moved, archived, and backed up as easily as any other file.

IDE 0, IDE 1 By default, two Integrated Drive Electronics (IDE) interfaces are presented to the
virtual machine. The IDE interface (controller and cable) is a standard way for a
storage devices (Floppy drives, hard drives and CD-ROM drives) to connect to
the virtual machine.

Keyboard Mirrors the keyboard that is connected to the virtual machine console when you
first connect to the console.

Memory The virtual hardware memory size determines how much memory applications
that are running inside the virtual machine have available to them. A virtual
machine cannot benefit from more memory resources than its configured virtual
hardware memory size.

Network Adapter ESX/ESXi networking features provide communication between virtual machines
on the same host, between virtual machines on different hosts, and between other
virtual and physical machines. When you configure a virtual machine, you can
add network adapters (NICs) and specify the adapter type.

72 VMware, Inc.
Chapter 7 Configuring Virtual Machines

Table 7-1. Virtual Machine Hardware (Continued)


Hardware Device Description

Parallel port Interface for connecting peripherals to the virtual machine. The virtual parallel
port can connect to a parallel port or a file on the host operating system. You can
add, remove, or configure virtual parallel ports.

PCI controller Bus on the virtual machine motherboard that communicates with components
such as hard disks and other devices. One PCI controller is presented to the virtual
machine. You cannot configure or remove this device.

PCI Device You can add up to six PCI VMDirectPath devices to a virtual machine. The devices
must be reserved for PCI passthrough on the host on which the virtual machine
runs.

Pointing device Mirrors the pointing device that is connected to the virtual machine console when
you first connect to the console.

PS2 controller Provides mouse virtualization. One PS2 controller is available to the virtual
machine. By default, when you power on a virtual machine, it uses a PS/2 mouse.
If the victual machine has a virtual mouse drive, or if you load a mouse driver,
vmouse absolute protocol is used. If a USB driver is loaded, the controller sends
a driver over USB protocol. If the USB mouse does not respond, the virtual
machine reverts to the vmouse or PS2 mouse.

Serial Port Interface for connecting peripherals to the virtual machine. The virtual serial port
can connect to a physical serial port, to a file on the host computer, or over the
network. You can also use it to establish a direct connection between two virtual
machines or a connection between a virtual machine and an application on the
host computer. A virtual machine can use up to four virtual serial ports. You can
add, remove, or configure virtual serial ports.

SCSI controller Provides access to virtual disks. The SCSI virtual controller appears to a virtual
machine as different types of controllers, including BusLogic Parallel, LSI Logic
Parallel, LSI Logic SAS, and VMware Paravirtual. You can change the SCSI
controller type, allocate bus sharing for a virtual machine, add a paravirtualized
SCSI controller, and enable or disable VMI paravirtualization.

SCSI device By default, a SCSI device interface is available to the virtual machine. The SCSI
interface is a typical way to connect storage devices (floppy drives, hard drives,
and DVD/CD-ROMs) to a virtual machine. You can add, remove, or configure
SCSI devices.

SIO controller Provides serial and parallel ports, floppy devices, and performs system
management activities. One SIO controller is available to the virtual machine. You
cannot configure or remove this device.

USB controller The USB hardware chip that provides USB function to the USB ports that it
manages. The virtual USB Controller is the software virtualization of the USB host
controller function in the virtual machine.

USB device You can add multiple USB devices, such as security dongles and mass storage
devices, to a virtual machine that runs on an ESX/ESXi host to which the devices
are physically attached.

VMCI Virtual Machine Communication Interface device. Provides a high-speed


communication channel between a virtual machine and the hypervisor. You can
also enable VMCI for communication between virtual machines. You cannot add

Virtual Machine Hardware Versions


The hardware version of a virtual machine reflects the virtual machine's supported virtual hardware features.
These features correspond to the physical hardware available on the ESX/ESXi host on which you create the
virtual machine. Virtual hardware features include BIOS, number of virtual PCI slots, maximum number of
CPUs, maximum memory configuration, and other characteristics typical to hardware.

When you create a virtual machine, you can accept the default hardware version, which always corresponds
to the host on which the virtual machine is created, or an earlier version.

74 VMware, Inc.
Chapter 7 Configuring Virtual Machines

Selecting an earlier hardware version is useful when you want to maintain compatibility with older hosts. A
virtual machine can have an earlier hardware version than that of the host on which it runs in the following
cases:
n You migrate a virtual machine created on an ESX/ESXi 3.x or earlier host to an ESX/ESXi 4.x host.
n You create a new virtual machine on an ESX 4.x host using an existing virtual disk that was created on an
ESX/ESXi 3.x or earlier host.
n You add a virtual disk created on an ESX/ESXi 3.x or earlier host to a virtual machine created on an ESX/
ESXi 4.x host.

Virtual machines with hardware versions earlier than version 4 can run on ESX/ESXi 4.x hosts, but have reduced
performance and capabilities. In particular, you cannot add or remove virtual devices on virtual machines with
hardware versions earlier than version 4 when they run on an ESX/ESXi 4.x host. To make full use of these
virtual machines, upgrade the virtual hardware as described in the Upgrade Guide.

Table 7-5 lists virtual machine hardware versions; the ESX/ESXi versions on which they can be created, edited,
and run; the vCenter Server versions on which they are fully supported; and a brief description of the hardware
version’s capabilities.

Table 7-5. Virtual Machine Hardware Versions

of the CPU parameters during virtual machine creation or after the guest operating system is installed. Some
actions require you to power off the virtual machine before changing the settings.
Understanding the following concepts can help you plan your CPU resource allocation strategy.

CPU The CPU or processor is the portion of a computer system that carries out the
instructions of a computer program and is the primary element carrying out
the computer's functions.

Core Comprises a logical execution unit containing an L1 cache and functional units
needed to execute programs. Cores can independently execute programs or
threads.

Thread A process that does not have a full stack of memory associated for it. The thread
is tied to a parent process. typically thread processes must run on the same
computer, but can execute simultaneously on separate cores of the same node.

Socket A physical connector on a computer motherboard that accepts a single physical


chip. Many motherboards can have multiple sockets that can in turn accept
multicore chips.

VMware, Inc. 77
vSphere Virtual Machine Administration Guide

Resource sharing Shares specify the relative priority or importance of a virtual machine or
resource pool. If a virtual machine has twice as many shares of a resource as
another virtual machine, it is entitled to consume twice as much of that resource
when these two virtual machines are competing for resources.

Resource allocation You can dynamically change resource allocation policies. For example, if at
year end the workload on Accounting increases, you can increase the
Accounting resource pool reserve.

Change the CPU Configuration


You can configure more than one virtual processor or CPU for a virtual machine using VMware Virtual SMP
for ESX.

You can configure a virtual machine that runs on an ESX/ESXi host to have up to eight virtual CPUs. A Virtual
machine cannot have more virtual CPUs than the actual number of logical CPUs on the host. The number of
logical CPUs is the number of physical processor cores or two times that number if hyperthreading is enabled.
For example, if a host has eight logical CPUs, you can configure the virtual machine for 8 virtual CPUs.

Not all guest operating systems support SMP, and some that do require reinstallation if the number of CPUs
changes. For more information about using SMP, search the VMware Knowledge Base.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Hardware tab and select CPUs.

3 Select the number of virtual processors for the virtual machine.

4 Click OK to save your changes and close the dialog box.

Allocate CPU Resources


You can change the amount of CPU resources allocated to a virtual machine by using the shares, reservations,
and limits settings.

A virtual machine has the following user-defined settings that affect its CPU resource allocation.

Limit Places a limit on the consumption of CPU time for a virtual machine. This value
is expressed in MHz.

Reservation Specifies the guaranteed minimum allocation for a virtual machine. The
reservation is expressed in MHz.

Shares Each virtual machine is granted a number of CPU shares. The more shares a
virtual machine has, the more often it gets a time slice of a CPU when there is
no CPU idle time. Shares represent a relative metric for allocating CPU
capacity.

Prerequisites
n Verify that you are connected to the vCenter Server or ESX/ESXi host on which the virtual machine runs.
n Verify that you have access to the virtual machine in the vSphere Client inventory list.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Resources tab and select CPU.

service console. You can use share allocation symbolic values to configure
their conversion into numeric values.
Reservation Guaranteed CPU allocation for this virtual machine.
Limit Upper limit for this virtual machine’s CPU allocation. Select Unlimited to
specify no upper limit.

4 Click OK to save your changes and close the dialog box.

Configure Multicore Virtual CPUs


VMware multicore virtual CPU support lets you control the number of cores per virtual CPU in a virtual
machine. This capability lets operating systems with socket restrictions use more of the host CPU's cores, which
increases overall performance.

You can configure how the virtual CPUs are assigned in terms of sockets and cores. For example, you can
configure a virtual machine with four virtual CPUs in the following ways:
n Four sockets with one core per socket
n Two sockets with two cores per socket
n One socket with four cores per socket

Using multicore virtual CPUs can be useful when you run operating systems or applications that can take
advantage of only a limited number of CPU sockets. Previously, each virtual CPU was, by default, assigned
to a single-core socket, so that the virtual machine would have as many sockets as virtual CPUs.

When you configure multicore virtual CPUs for a virtual machine, CPU hot Add/remove is disabled.

For more information about multicore CPUs, see the vSphere Resource Management Guide. You can also search
the VMware KNOVA database for articles about multicore CPUs.

CAUTION You must assign a value to configuration parameter keywords. If you don't assign a value, the
keyword can return a value of 0, false, or disable, which can result in a virtual machine that cannot power on.

Prerequisites

IMPORTANT To use the VMware multicore virtual CPU feature, you must be in compliance with the
requirements of the operating system EULA.

n Verify that the virtual machine is powered off.


n Verify that you have virtual machine hardware version 7 or later.
n Verify that the total number of virtual CPUs for the virtual machine divided by the number of cores per
socket is a positive integer.
Required Privilege: Advanced

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Select the Hardware tab and select CPUs.

3 Select the number of virtual processors.

4 Select the Options tab and Click General in the Advanced options list.

6 Click Add Row and type cpuid.coresPerSocket in the Name column.

You cannot make changes to the name (keyword) after you enter it.

7 Type a value (2, 4, or 8) in the Value column.


The number of virtual CPUs must be divisible by the number of cores per socket. The coresPerSocket
setting must be a power of two.

8 Click OK and power on the virtual machine.


You can verify the CPU settings for the virtual machine on the Resource Allocation tab.

Configuring Advanced CPU Scheduling Settings


You can select CPU options that involve scheduling the virtual machine processing to physical processor cores
and hyperthreads. ESX generally manages processor scheduling well, even when hyperthreading is enabled.
These settings are useful only for detailed tweaking of critical virtual machines.

Configure Hyperthreaded Core Sharing


You can select how the virtual CPUs of a virtual machine share physical cores on a hyperthreaded system.

Hyperthreading technology allows a single physical processor to behave like two logical processors. The
hyperthreaded core sharing option provides detailed control over whether to schedule a virtual machine to
share a physical processor core. The processor can run two independent applications at the same time.
Although hyperthreading does not double the performance of a system, it can increase performance by better
utilizing idle resources.

Prerequisites
n The hyperthreaded core sharing option must be enabled in your system's BIOS settings. For more
information, see the Resource Management Guide.
n Power off the virtual machine.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Resources tab and select Advanced CPU.

3 Select a mode from the Hyperthreading Sharing Mode drop-down menu.

Option Description
Any (default) The virtual CPUs of this virtual machine can share cores with other virtual
CPUs of this or other virtual machines.
None The virtual CPUs of this virtual machine have exclusive use of a processor
core whenever they are scheduled to it. The other hyperthread of the core is
halted while this virtual machine is using the core.
Internal On a virtual machine with exactly two virtual processors, the two virtual
processors are allowed to share one physical core (at the discretion of the
host scheduler), but this virtual machine never shares a core with any other
virtual machine. If this virtual machine has any other number of processors
other than two, this setting is the same as the None setting.

Configure Processor Scheduling Affinity


The Scheduling Affinity option gives you detailed control over how virtual machine CPUs are distributed
across the host's physical cores (and hyperthreads if hyperthreading is enabled). This panel does not appear
for virtual machines in a DRS cluster or when the host has only one processor core and no hyperthreading.

Using CPU affinity, you can assign a virtual machine to a specific processor. This assignment allows you to
restrict the assignment of virtual machines to a specific available processor in multiprocessor systems.

For potential issues with CPU affinity, see the Resource Management Guide.

Prerequisites

Power off the virtual machine.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Resources tab and select Advanced CPU.

3 In the Scheduling Affinity panel, enter a comma-separated list of hyphenated processor ranges.

For example, "0,4-7" would indicate affinity with CPUs 0,4,5,6, and 7. Selecting all processors is identical
to selecting no affinity. You must provide at least as many processor affinities as you have virtual CPUs.

4 Click OK to save your changes and close the dialog box.

Change CPU Hot-Plug Settings


The CPU hot plug option lets you add or remove CPU resources for a virtual machine while the machine is
powered on.

When you configure multicore virtual CPUs for a virtual machine, CPU hot Plug is disabled.

Adding CPU resources to a running virtual machine (with CPU hot plug enabled) disconnects and reconnects
all USB passthrough devices connected to that virtual machine.

Prerequisites

Verify that the virtual machine is running under the following conditions:
n VMware Tools is installed (required for hot plug functionality with Linux guest operating systems).
n The virtual machine has a guest operating system that supports CPU hot plug.
n The virtual machine is using hardware version 7 or later.
n CPU hot plug is enabled on the Options tab of the Virtual Machine Properties dialog box.

Change CPU Identification Mask Settings


CPU identification (CPU ID) masks control the CPU features visible to the virtual machine's guest operating
system. Masking or hiding CPU features can make a virtual machine widely available to ESX/ESXi hosts for
migration. vCenter Server compares the CPU features available to a virtual machine with the CPU features of
the destination host to determine whether to allow or disallow migration with vMotion.

For example, masking the AMD No eXecute (NX) and the Intel eXecute Disable (XD) bits prevents the virtual
machine from using these features, but provides compatibility that allows you to migrate virtual machines to
ESX/ESXi hosts that do not include this capability. When the NX/XD bit is visible to the guest operating system,
the virtual machine can use this feature, but you can migrate the virtual machine only to hosts on which the
feature is enabled.

NOTE You rarely need to change the CPU identification mask configuration settings. Almost all changes are
made only to the NX/XD bit.

See the vSphere Datacenter Administration Guide for detailed information about vMotion compatibility and CPU
masks.

Prerequisites
n Verify that you have access to the virtual machine in the vSphere Client inventory list.
n Power off the virtual machine.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Options tab and under Advanced, select CPUID Mask.

Memory Virtual Machine Configuration


You can add, change, or configure virtual machine memory resources or options to enhance virtual machine
performance. You can set most of the memory parameters during virtual machine creation or after the guest
operating system is installed. Some actions require that you power off the virtual machine before changing the
settings.

Memory resource configuration is distinct from the virtual hardware memory size, which you configure on the
Hardware tab. The memory resource setting determines how much of the host's memory is allocated to a virtual
machine. The virtual hardware memory size determines how much memory applications that are running
inside the virtual machine have available to them. A virtual machine cannot benefit from more memory
resources than its configured virtual hardware memory size. The ESX/ESXi host caps memory resource use to
the maximum useful for the virtual machine, so you can accept the default of Unlimited memory resources.

Change the Memory Configuration


You can reconfigure the memory allocated to a virtual machine's hardware.

Minimum memory size is 4MB. Minimum and maximum memory size depends on the host and the guest
operating system type. The memory size must be a multiple of 4MB. The maximum for best performance
represents the threshold above which the host's physical memory is insufficient to run the virtual machine at
full speed. This value fluctuates as conditions on the host change (as virtual machines are powered on or off,
for example).

When you add memory to a virtual machine while it is powered on, the amount you add cannot exceed 16
times the amount of memory the virtual machine had when it was powered on.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Hardware tab and select Memory.

3 Adjust the amount of memory allocated to the virtual machine.

4 Click OK to save your changes and close the dialog box.

VMware, Inc. 83
vSphere Virtual Machine Administration Guide

Allocate Memory Resources


You can allocate memory resources for a virtual machine and specify reservations, limits, and shares.

A virtual machine has three user-defined settings that affect its memory resource allocation.

Limit Places a limit on the consumption of memory for a virtual machine. This value
is expressed in megabytes.

Reservation Specifies the guaranteed minimum allocation for a virtual machine. The
reservation is expressed in megabytes.

Shares Each virtual machine is granted a number of memory shares. The more shares
a virtual machine has, the more often it gets a time slice of a memory when
there is no memory idle time. Shares represent a relative metric for allocating
memory capacity. For more information about share values, see the Resource
Management Guide.

Assigning a virtual machine a reservation larger than its configured memory is wasteful. The vSphere Client
does not allow you to make such an assignment on the Resources tab. If you give a virtual machine a large
reservation and then reduce its configured memory size on the Hardware tab, the reservation is reduced to
match the new configured memory size. You must power off the virtual machine before configuring memory
resources.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Resources tab and select Memory.

3 Allocated the memory capacity for this virtual machine.

Option Description
Shares The values Low, Normal, High, and Custom are compared to the sum of all
shares of all virtual machines on the server and, on ESX/ESXi hosts, the
service console. You can use share allocation symbolic values to configure
their conversion into numeric values.
Reservation Guaranteed memory allocation for this virtual machine.
Limit Upper limit for this virtual machine’s memory allocation.
Unlimited No upper limit is specified.

4 Click OK to save your changes and close the dialog box.

Change Memory Hot-Add Settings


Memory hot add lets you add memory resources for a virtual machine while the machine is powered on.

Prerequisites
n The virtual machine has a guest operating system that supports Memory hot add functionality.
n The virtual machine is using hardware version 7 or later.
n Memory hot add is enabled on the Options tab of the Virtual Machine Properties dialog box.
n VMware Tools is installed.

84 VMware, Inc.

3 Enable or disable memory hot add.


n Enable memory hot add for this virtual machine.
n Disable memory hot add for this virtual machine.

4 Click OK to save your changes and close the dialog box.

Associate Memory Allocations with a NUMA Node


You can specify that all future memory allocations on a virtual machine use pages associated with a single
NUMA node (also known as manual memory affinity). When the virtual machine uses local memory, the
performance improves on that virtual machine.

The following conditions apply to memory optimization with NUMA:


n The NUMA option is available on the Advanced Memory Resources page only if the host uses NUMA
memory architecture.
n Affinity settings are meaningful only when used to tweak the performance of a specific set of virtual
machines on one host. This option is not available when the virtual machine resides on a DRS cluster. All
affinity values are cleared when you move the virtual machine to a new host.
n You can specify nodes to use for future memory allocations only if you have also specified CPU affinity.
If you make manual changes only to the memory affinity settings, automatic NUMA rebalancing does not
work properly.
n Checking all the boxes is the same as applying no affinity.

For information about NUMA and advanced memory resources, including usage examples, see the Resource
Management Guide.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Select the Resources tab, and select Memory.

3 In the NUMA Memory Affinity panel, set the NUMA node affinity for the virtual machine.
n No affinity
n Use memory from nodes

4 Click OK to save your changes and close the dialog box.

Change the Swap File Location


When a virtual machine is powered on, the system creates a VMkernel swap file to serve as a backing store for
the virtual machine's RAM contents. You can accept the default swap file location or save the file to a different
location. By default, the swap file is stored in the same location as the virtual machine's configuration file.

For more information about host swap file settings, see the vSphere Datacenter Administration Guide. For more
information about cluster settings, see the Resource Management Guide.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Option tab and under Advanced, select Swapfile Location.

4 Click OK to save your changes and close the dialog box.

Virtual Disk Configuration


You can add virtual disks and add more space to existing disks, even when the virtual machine is running.
You can set most of the virtual disk parameters during virtual machine creation or after you install the guest
operating system.

You can store virtual machine data in a new virtual disk, an existing virtual disk, or a mapped SAN LUN. A
virtual disk, which appears as a single hard disk to the guest operating system, is composed of one or more
files on the host file system. You can easily copy or move virtual disks on the same hosts or between hosts.

For virtual machines running on an ESX/ESXi host, you can store the virtual machine data directly on a SAN
LUN instead of storing it in a virtual disk file. This is useful if you are running applications in your virtual
machines that must know the physical characteristics of the storage device. Additionally, mapping a SAN LUN
allows you to use existing SAN commands to manage storage for the disk.

When you map a LUN to a VMFS volume, vCenter Server creates a raw device mapping (RDM) file that points
to the raw LUN. Encapsulating disk information in a file allows vCenter Server to lock the LUN so that only
one virtual machine can write to it. This file has a .vmdk extension, but the file contains only disk information
that describes the mapping to the LUN on the ESX/ESXi system. The actual data is stored on the LUN. You
cannot deploy a virtual machine from a template and store its data on a LUN. You can store only its data in a
virtual disk file.

Change the Virtual Disk Configuration


You can change the virtual device node, the size of the disk, and the persistence mode for virtual disk
configuration for a virtual machine.

NOTE The Manage Paths feature for RDM disks is not available for virtual machines on legacy hosts running
versions of ESX Server earlier than 3.0.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Hardware tab and select the hard disk to modify.

The name of the disk file and the disk type (thick or thin) appear in the upper-right pane.

3 Select a Virtual Device Node type from the drop-down menu.

4 To change the size of the disk, enter a new value in the Provisioned Size text box.

86 VMware, Inc.
Chapter 7 Configuring Virtual Machines

5 (Optional) Select the virtual disk Independent mode and select an option.

Option Description
Persistent The disk operates normally except that changes to the disk are permanent
even if the virtual machine is reverted to a snapshot.
Nonpersistent The disk appears to operate normally, but whenever the virtual machine is
powered off or reverted to a snapshot, the contents of the disk return to their
original state. All later changes are discarded.

Independent disks are not affected by snapshots.

6 Click OK to save your changes and close the dialog box.

Add a Hard Disk to a Virtual Machine


When you add a hard disk to a virtual machine, you can create a new virtual disk, add an existing virtual disk,
or add a mapped SAN LUN.
In most cases, you can accept the default device node. For a hard disk, a nondefault device node is useful to
control the boot order or to have different SCSI controller types. For example, you might want to boot off an
LSI Logic controller and share a data disk with another virtual machine using a Buslogic controller with bus
sharing turned on.

NOTE You cannot use migration with vMotion to migrate virtual machines that use raw disks for clustering
purposes.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

Use Disk Shares to Prioritize Virtual Machines


You can change the disk resources for a virtual machine. If multiple virtual machines access the same VMFS
datastore and the same logical unit number (LUN), use disk shares to prioritize the disk accesses from the
virtual machines. Disk shares distinguish high-priority from low-priority virtual machines.

You can allocate the host disk's I/O bandwidth to the virtual hard disks of a virtual machine. Disk I/O is a host-
centric resource so you cannot pool it across a cluster.

Shares is a value that represents the relative metric for controlling disk bandwidth to all virtual machines. The
values are compared to the sum of all shares of all virtual machines on the server and, on an ESX host, the
service console.

Disk shares are relevant only within a given ESX/ESXi host. The shares assigned to virtual machines on one
host have no effect on virtual machines on other hosts.

You can select an IOP limit, which sets an upper bound for storage resources that are allocated to a virtual
machine. IOPs are the number of I/O operations per second.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Resources tab and select Disk.

3 In the Resource Allocation panel, select the virtual hard disk to change.

4 Click the Shares column and change the value to allocate a number of shares of its disk bandwidth to the
virtual machine.
n Low (500)
n Normal (1000)
n High (2000)
n Custom

When you select a shares symbolic value, the numeric value appears in the Shares Value column. You
can select Custom to enter a user-defined shares value.

5 Click the Limit - IOPS column and enter the upper limit of storage resources to allocate to the virtual
machine.

SCSI Controller Configuration


To access virtual disks, a virtual machine uses virtual SCSI controllers. These virtual controllers appear to a
virtual machine as different types of controllers, including BusLogic Parallel, LSI Logic Parallel, LSI Logic SAS,
and VMware Paravirtual. You can change the SCSI controller type, allocate bus sharing for a virtual machine,
add a paravirtualized SCSI controller, and enable or disable VMI paravirtualization.

Change the SCSI Bus Sharing Configuration


You can set the type of SCSI bus sharing for a virtual machine and indicate whether the SCSI bus is shared.
Depending on the type of sharing, virtual machines can access the same virtual disk simultaneously on the
same server or on any server.

You can change the SCSI controller configuration for a virtual machine on an ESX/ESXi host only.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Hardware tab and select a SCSI Controller in the hardware list.

3 Select the type of sharing in the SCSI Bus Sharing list.

Option Description
None Virtual disks cannot be shared by other virtual machines.
Virtual Virtual disks can be shared by virtual machines on the same server.
Physical Virtual disks can be shared by virtual machines on any server.

4 Click OK to save your changes and close the dialog box.

Change the SCSI Controller Type


You configure virtual SCSI controllers on your virtual machines to attach virtual disks and RDMs to.

The choice of SCSI controller does not affect whether your virtual disk is an IDE or SCSI disk. The IDE adapter
is always ATAPI. The default for your guest operating system is already selected. Older guest operating
systems default to the BusLogic adapter.

If you create an LSI Logic virtual machine and add a virtual disk that uses BusLogic adapters, the virtual
machine boots from the BusLogic adapters disk. LSI Logic SAS is available only for virtual machines with
hardware version 7. Disks with snapshots might not experience performance gains when used on LSI Logic
SAS, VMware Paravirtual, and LSI Logic Parallel adapters.

You can change the SCSI controller configuration for a virtual machine on an ESX/ESXi host only.

CAUTION Changing the SCSI controller type might result in a virtual machine boot failure.

About VMware Paravirtual SCSI Adapters


Paravirtual SCSI (PVSCSI) adapters are high performance storage adapters that can result in greater
throughput and lower CPU utilization. PVSCSI adapters are best suited for high performance storage
environments.

PVSCSI adapters are available for virtual machines running hardware version 7 and later. They are supported
on the following guest operating systems:
n Windows Server 2008 R2 (64bit)
n Windows Server 2008 (32bit and 64bit)
n Windows Server 2003 (32bit and 64bit)
n Windows XP (32bit and 64bit)
n Windows Vista (32bit and 64bit)
n Windows 7 (32bit and 64bit)
n Red Hat Linux 5 (32bit and 64bit)

PVSCSI adapters have the following limitations:


n Disks on PVSCSI adapters might not experience performance gains if they have snapshots or if memory
on the ESX host is over committed.
n If you upgrade from RHEL 5 to an unsupported kernel, you might not be able to access data on the disks
attached to a PVSCSI adapter. To regain access to such disks:

a Upgrade the guest kernel but do not restart the guest.

b Run the VMware Tools configuration with the kernel-version parameter and pass the kernel version
within the guest:
vmware-config-tools.pk --kernel-version kernel_version

Run name -r to determine the version of the running kernel.

c Restart the guest.


n MSCS clusters are not supported.
n PVSCSI adapters do not support boot disks (the disk that contains the system software) on Red Hat Linux
5 virtual machines. Attach the boot disk to the virtual machine by using any of the other supported adapter
types.

Enable and Disable VMI Paravirtualization


VMI is a paravirtualization standard that enables improved performance for virtual machines capable of using
it. Currently, this feature is available only for those versions of the Linux guest operating system that support
VMI paravirtualization.

Enabling paravirtualization uses one of the virtual machine’s six virtual PCI slots. Enabling paravirtualization
can limit how and where the virtual machine can be migrated. Consider the following before enabling this
feature:
n These hosts support VMI paravirtualization: ESX/ESXi 3.5 and greater, and Workstation 6.0 and greater.
Hardware version 4 virtual machines with paravirtualization enabled that are created on ESX hosts can
be migrated to Workstation hosts without loss of functionality.
n A virtual machine with paravirtualization enabled and that is powered off can be moved manually to a
host that does not support paravirtualization. However, this can result in reduced performance.
n A virtual machine with paravirtualization enabled and that is powered on or in a suspended power state
can not be migrated to a host that does not support paravirtualization.
n Automated vCenter Server DRS migrations of virtual machines with paravirtualization enabled to hosts
that do not support paravirtualization are not allowed.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Options tab and under advanced, select Paravirtualization.

3 Select Support VMI Paravirtualization to enable VMI Paravirtualization.

4 Click OK to save your changes and close the dialog box.

Add a Paravirtualized SCSI Adapter


You can add a paravirtual SCSI (PVSCSI) high performance storage adapter to provide greater throughput
and lower CPU utilization.

PVSCSI adapters are best suited for environments, especially SAN environments, running I/O-intensive
applications.

Windows 2003 and 2008 guest operating systems support boot disk devices attached to a PVSCSI adapter.

PVSCSI adapters do not support bootable disks on Red Hat Linux 5 virtual machines. You must configure such
virtual machines with a primary SCSI adapter other than PVSCSI to support a disk where the system software
is installed.

Prerequisites

An existing virtual machine with a guest operating system and VMware Tools installed.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Hardware tab and click Add.

Network Virtual Machine Configuration


ESX/ESXi networking features provide communication between virtual machines on the same host, between
virtual machines on different hosts, and between other virtual and physical machines. The networking features
also allow management of ESX/ESXi hosts and provide communication between VMkernel services (NFS,
iSCSI, or VMware vMotion) and the physical network. When you configure networking for a virtual machine,
you select or change an adapter type, a network connection, and whether to connect the network when the
virtual machine powers on.

Network Adapter Types


When you configure a virtual machine, you can add network adapters (NICs) and specify the adapter type.

The type of network adapters that are available depend on the following factors:
n The virtual machine version, which depends on what host created it or most recently updated it.
n Whether the virtual machine has been updated to the latest version for the current host.
n The guest operating system.

92 VMware, Inc.
Chapter 7 Configuring Virtual Machines

The following NIC types are supported:

E1000 Emulated version of the Intel 82545EM Gigabit Ethernet NIC, with drivers
available in most newer guest operating systems, including Windows XP and
later and Linux versions 2.4.19 and later.

Flexible Identifies itself as a Vlance adapter when a virtual machine boots, but initializes
itself and functions as either a Vlance or a VMXNET adapter, depending on
which driver initializes it. With VMware Tools installed, the VMXNET driver
changes the Vlance adapter to the higher performance VMXNET adapter.

Vlance Emulated version of the AMD 79C970 PCnet32 LANCE NIC, an older 10 Mbps
NIC with drivers available in most 32bit guest operating systems except
Windows Vista and later. A virtual machine configured with this network
adapter can use its network immediately.

VMXNET Optimized for performance in a virtual machine and has no physical


counterpart. Because operating system vendors do not provide built-in drivers
for this card, you must install VMware Tools to have a driver for the VMXNET
network adapter available.

VMXNET 2 (Enhanced) Based on the VMXNET adapter but provides high-performance features
commonly used on modern networks, such as jumbo frames and hardware
offloads. VMXNET 2 (Enhanced) is available only for some guest operating
systems on ESX/ESXi 3.5 and later.

VMXNET 3 Next generation of a paravirtualized NIC designed for performance. VMXNET


3 offers all the features available in VMXNET 2 and adds several new features,
such as multiqueue support (also known as Receive Side Scaling in Windows),
IPv6 offloads, and MSI/MSI-X interrupt delivery. VMXNET 3 is not related to
VMXNET or VMXNET 2.

For network adapter compatibility considerations, see the VMware Compatibility Guide.

Network Adapters and Legacy Virtual Machines


Legacy virtual machines are virtual machines that are supported by the product in use, but are not current for
that product. The default network adapter types for all legacy virtual machines depend on the adapters
available and compatible to the guest operating system and the version of virtual hardware on which the virtual
machine was created.

If you do not upgrade a virtual machine to correspond with an upgrade to a newer version of an ESX/ESXi
host, your adapter settings remain unchanged. If you upgrade your virtual machine to take advantage of newer
virtual hardware, your default adapter settings will likely change to be compatible with the guest operating
system and upgraded host hardware.

To verify the network adapters that are available to your supported guest operating system for a particular
version of vSphere ESX/ESXi, see the VMware Compatibility Guide.

Change the Virtual Network Adapter (NIC) Configuration


You can change the power-on connection setting, the MAC address, and the network connection for the virtual
network adapter configuration for a virtual machine.

Manually assigned MAC addresses for virtual machines on ESX/ESXi hosts must begin with the OUI 00:50:56.
The address must have the form 00:50:56:XX:YY:ZZ, where XX is a hexadecimal number between 00 and 3F,
and YY and ZZ are hexadecimal numbers between 00 and FF.

Parallel and Serial Port Configuration


Parallel and serial ports are interfaces for connecting peripherals to the virtual machine. The virtual serial port
can connect to a physical serial port or to a file on the host computer. You can also use it to establish a direct
connection between two virtual machines or a connection between a virtual machine and an application on
the host computer. You can add parallel and serial ports, change the serial port configuration, and configure
Fibre Channel NPIV settings for the virtual machine.

Change the Serial Port Configuration


A virtual machine can use up to four virtual serial ports. The virtual serial port can connect to a physical serial
port or to a file on the host computer. It can also be used to set up a direct connection between two virtual

Configure Fibre Channel NPIV Settings


N-port ID virtualization (NPIV) provides the ability to share a single physical Fibre Channel HBA port among
multiple virtual ports, each with unique identifiers. This capability lets you control virtual machine access to
LUNs on a per-virtual machine basis.

Each virtual port is identified by a pair of world wide names (WWNs): a world wide port name (WWPN) and
a world wide node name (WWNN). These WWNs are assigned by vCenter Server.

For detailed information on how to configure NPIV for a virtual machine, see the Fibre Channel SAN
Configuration Guide.

NPIV support is subject to the following limitations:


n NPIV must be enabled on the SAN switch. Contact the switch vendor for information about enabling NPIV
on their devices.
n NPIV is supported only for virtual machines with RDM disks. Virtual machines with regular virtual disks
continue to use the WWNs of the host’s physical HBAs.
n The physical HBAs on the ESX host must have access to a LUN using its WWNs in order for any virtual
machines on that host to have access to that LUN using their NPIV WWNs. Ensure that access is provided
to both the host and the virtual machines.
n The physical HBAs on the ESX host must support NPIV. If the physical HBAs do not support NPIV, the
virtual machines running on that host will fall back to using the WWNs of the host’s physical HBAs for
LUN access.
n Each virtual machine can have up to 4 virtual ports. NPIV-enabled virtual machines are assigned exactly
4 NPIV-related WWNs, which are used to communicate with physical HBAs through virtual ports.
Therefore, virtual machines can utilize up to 4 physical HBAs for NPIV purposes.

You can view or edit the virtual machines WWNs on the Options tab.

Prerequisites
n To edit the virtual machine’s WWNs, power off the virtual machine.
n Verify that the virtual machine has a datastore containing a LUN that is available to the host.

USB Device Passthrough Configuration from an ESX/ESXi Host to a


Virtual Machine
You can add multiple USB devices, such as security dongles and mass storage devices, to a virtual machine
that runs on an ESX/ESXi host to which the devices are physically attached. Knowledge of device components
and their behavior, virtual machine requirements, feature support, and ways to avoid data loss can help make
USB device passthrough from an ESX/ESXi host to a virtual machine successful.

How USB Device Passthrough Technology Works


When you attach a USB device to a physical host, the device is available only to virtual machines that run on
that host. The device cannot connect to virtual machines that run on another host in the datacenter

104 VMware, Inc.


Chapter 7 Configuring Virtual Machines

A USB device is available to only one virtual machine at a time. When a device is connected to a powered-on
virtual machine, it is not available to connect to other virtual machines that run on the host. When you remove
the active connection of a USB device from a virtual machine, it becomes available to connect to other virtual
machines that run on the host. host.

Connecting a USB passthrough device to a virtual machine that runs on the ESX/ESXi host to which the device
is physically attached requires an arbitrator, a controller, and a physical USB device or device hub.

USB Arbitrator Manages connection requests and routes USB device traffic. The arbitrator is
installed and enabled by default on ESX/ESXi hosts. It scans the host for USB
devices and manages device connection among virtual machines that runs on
the host. It routes device traffic to the correct virtual machine instance for
delivery to the guest operating system. The arbitrator monitors the USB device
and prevents other virtual machines from using it until you release it from the
virtual machine it is connected to.

If vCenter Server polling is delayed, a device that is connected to one virtual


machine might appear as though it is available to add to another virtual
machine. In such cases, the arbitrator prevents the second virtual machine from
accessing the USB device.

USB Controller The USB hardware chip that provides USB function to the USB ports that it
manages. The virtual USB Controller is the software virtualization of the USB
host controller function in the virtual machine.

USB controller hardware and modules that support USB 2.0 and USB 1.1
devices must exist on the host. Only one virtual USB controller is available to
each virtual machine. The controller supports multiple USB 2.0 and USB 1.1
USB devices in the virtual computer. The controller must be present before you
can add USB devices to the virtual machine.

The USB arbitrator can monitor a maximum of 15 USB controllers. Devices


connected to controllers numbered 16 or greater are not available to the virtual
machine.

USB Devices You can add up to 20 USB devices to a virtual machine. This is the maximum
number of devices supported for simultaneous connection to one virtual
machine. The maximum number of USB devices supported on a single ESX/
ESXi host for simultaneous connection to one or more virtual machines is also
20. VMware provides support for multiple USB devices.

For a list of supported USB devices for passthrough from an ESX/ESXi host to
a virtual machine, see the VMware knowledge base article at
http://kb.vmware.com/kb/1021345.

USB Passthrough Device Autoconnect Feature


When you add a USB device connection to a virtual machine, the autoconnect feature is enabled for this device
connection. It is not disabled until you remove the device connection from the virtual machine.

With autoconnect enabled, the device connection automatically re-establishes in the following cases:
n The virtual machine is cycling through power operations, such as Power Off/Power On, Reset, Pause/
Resume.
n The device is unplugged from the host then plugged back in to the same USB port.
n The device is power cycled but has not changed its physical connection path.
n The device is mutating identity during a different stage of usage.

VMware, Inc. 105


vSphere Virtual Machine Administration Guide

The USB passthrough autoconnect feature identifies the device by using the USB path of the device on the host.
That is, it uses the physical topology and port location, rather than the device identity. This feature can seem
confusing if you expect the autoconnect feature to match the connection target by device ID.

If the same device is plugged back in to the host through a different USB path (that is, a different port), it will
not be able to automatically re-establish connection with the virtual machine. If you unplug the device from
the host and plug in a different device to the same USB path, the new device appears and is connected to the
virtual machine by the autoconnect feature enabled by the previous device connection.

Autoconnect is useful in cases where devices mutate during usage. For example, for iPhones and other such
devices, the device VID:PID changes during software or firmware upgrades. The upgrade process disconnects
and reconnects the devices to the USB port.

The USB port is speed-specific. The autoconnect feature assumes that devices do not transition from USB 1.1
(low/full speed) to USB 2.0 (high speed) or the reverse. You cannot interchange USB 2.0 high speed devices
with USB 1.1 devices. For example, you might connect a USB 2.0 high-speed device to a port and connect that
device to the virtual machine. If you unplug the device from the host and plug a USB 1.1 device into the same
port, the device does not connect to the virtual machine.

For a list of supported USB devices for passthrough from an ESX/ESXi host to a virtual machine, see the VMware
knowledge base article at http://kb.vmware.com/kb/1021345.

VMware Features Available with USB Device Passthrough


Migration with vMotion and DRS are supported with USB device passthrough from an ESX/ESXi host to a
virtual machine.

The features listed in Table 7-6 are available with USB device passthrough.

Table 7-6. VMware Features Available for USB Passthrough from an ESX/ESXi Host to a Virtual Machine
Feature Supported with USB Device Passthrough

Distributed power management No

DRS Yes

Fault Tolerance No

vMotion Yes

If all USB devices connected to a virtual machine have vMotion support enabled, you can migrate that virtual
machine with the connected USB devices. For details, see “Configuring USB Passthrough Devices for vMotion,”
on page 109.

If a host with connected USB devices resides in a DRS cluster with distributed power management (DPM)
enabled, you must disable DPM for that host. Otherwise DPM might turn off the host with the device, which
would disconnect the device from the virtual machine that is using it.

106 VMware, Inc.


Chapter 7 Configuring Virtual Machines

Virtual Machine Functions that Can Result in Data Loss with USB Devices
Virtual machine functions can affect USB device behavior. Before you start the following tasks, be aware of
how the operation affects USB device connections.
n Before you hot add memory, CPU, or PCI devices, you must remove any USB devices. Hot adding these
resources disconnects USB devices, which might result in data loss.
n Before you suspend a virtual machine, make sure that a data transfer is not in progress. During the
suspend/resume process, USB devices behave as if they have been disconnected, then reconnected. For
information about suspend and resume behavior after migration with vMotion, see “Configuring USB
Passthrough Devices for vMotion,” on page 109.
n Before you change the state of the arbitrator, make sure that USB devices residing on the host are not
attached to a virtual machine. If USB devices become unavailable to a virtual machine, it is possible that
a host administrator has disabled the arbitrator. When an administrator stops or disconnects the arbitrator
for troubleshooting or other purposes, USB devices attached to that host become unavailable to the virtual
machine. If a data transfer is taking place at this time, you might lose the data. To reestablish the arbitrator,
the administrator must reboot the host.

Setting Up Physical USB Connections on an ESX/ESXi Host


You can connect and chain multiple USB hubs and devices to an ESX/ESXi host. Careful planning and
knowledge of hub behavior and limitations can help ensure that your devices work optimally.

USB physical bus topology defines how USB devices connect to the host. Support for USB device passthrough
to a virtual machine is available if the physical bus topology of the device on the host does not exceed tier
seven. The first tier is the USB host controller and root hub. The last tier is the target USB device. You can
cascade up to five tiers of external (or internal) hubs between the root hub and the target USB device. An
internal USB hub attached to the root hub or built into a compound device counts as one tier.

The quality of the physical cables, hubs, devices, and power conditions can affect USB device performance. To
ensure the best results, keep the host USB bus topology as simple as possible for the target USB device, and
use caution when you deploy new hubs and cables into the topology. The following conditions can affect USB
behavior:
n Communication delay between the host and virtual machine increases as the number of cascading hubs
increases.
n Connecting or chaining multiple external USB hubs increases device enumeration and response time,
which can introduce uncertainly to the power support to the connected USB devices.
n Chaining hubs together also increases the chance of port and hub error, which can cause the device to lose
connection to a virtual machine.
n Certain hubs can cause USB device connections to be unreliable, so use care when you add a new hub to
an existing setup. Connecting certain USB devices directly to the host rather than to a hub or extension
cable might resolve their connection or performance issues.

NOTE To prevent additional problems, be aware of the physical constraints of long-term deployment in a
machine room environment. Small devices are easily damaged by being stepped on or knocked loose.

In some cases, you must hard reset the device and hub to restore the device to a working state.

For a list of supported USB devices for passthrough from an ESX/ESXi host to a virtual machine, see the VMware
knowledge base article at http://kb.vmware.com/kb/1021345.

VMware, Inc. 107


vSphere Virtual Machine Administration Guide

USB Compound Devices


For compound devices, the virtualization process filters out the USB hub so that it is not visible to the virtual
machine. The remaining USB devices in the compound appear to the virtual machine as separate devices. You
can add each device to the same virtual machine or to different virtual machines if they run on the same host.

For example, the Aladdin HASP HL Drive USB dongle package contains three devices (0529:0001 HASP dongle,
13fe:1a00 Hub, 13fe:1d00 Kingston Drive). The Virtualization process filters out the USB hub. The remaining
Aladdin HASP HL Drive USB dongle devices (one Aladdin HASP dongle and one Kingston Drive) appear to
the virtual machine as individual devices. You must add each device separately to make it accessible to the
virtual machine.

USB CD/DVD-ROM Devices


The host treats USB CD/DVD-ROM devices as SCSI devices. Hot adding and removing these devices is not
supported.

Add USB Devices to an ESX/ESXi Host


You can add multiple USB devices to ESX/ESXi hosts so that virtual machines that run on the hosts can access
the devices. The number of devices that you can add depends on several factors, such as how the devices and
hubs connect (chain) together and the device type.

Each ESX/ESXi host has several USB ports. The number of ports on each host depends on the physical setup
of the host. When you calculate the depth of hub chaining, remember that on a typical server the front ports
connect to an internal hub.

The USB arbitrator can monitor a maximum of 15 USB controllers. If your system includes controllers that
exceed the 15 controller limit and you connect USB devices to them, the devices are not available to the virtual
machine.

The host treats USB CD/DVD-ROM devices as SCSI devices. Hot adding and removing these devices is not
supported.

Prerequisites
n If a host has attached USB devices and resides in a DRS cluster with DPM enabled, disable DPM for that
host. See the Resource Management Guide for instructions about overriding the default DPM setting for an
individual host.
n Make sure that you know the virtual machine requirements for USB devices. See “Setting Up Physical
USB Connections on an ESX/ESXi Host,” on page 107.
n Verify that the host is powered off before you add USB CD/DVD-ROM devices.

Procedure
u To add a USB device to an ESX/ESXi host, connect the device to an available port or hub.

Allow several minutes for vCenter Server to capture the state of the USB device. vCenter Server polling
delays can cause a lag between the time the physical USB device is attached to the host and when it appears
in the virtual machine Add Hardware wizard.

The USB device appears in the virtual machine Add Hardware wizard device list.

What to do next

You can now add the device to the virtual machine.

108 VMware, Inc.


Chapter 7 Configuring Virtual Machines

Add a USB Controller to a Virtual Machine


By default, a USB controller is available to a virtual machine if the host supports USB passthrough from an

exceed the 15 controller limit and you connect USB devices to them, the devices are not available to the virtual
machine.

Prerequisites
n The controller must be present. Add a USB controller, if needed.
n ESX/ESXi hosts must have USB controller hardware and modules that support USB 2.0 and USB 1.1 devices
present.

Configuring USB Passthrough Devices for vMotion


You can migrate a virtual machine to another ESX/ESXi host in the same datacenter and maintain the USB
passthrough device connections to the original host.

If a virtual machine has USB devices attached that pass through to an ESX/ESXi host, you can migrate that
virtual machine with the devices attached.

For a successful migration, review the following conditions:


n You must configure all USB passthrough devices connected to a virtual machine for vMotion. If one or
more devices is not configured for vMotion, the migration cannot proceed. For troubleshooting details, see
“Error Message When You Try to Migrate Virtual Machine with USB Devices Attached,” on page 112.
n When you migrate a virtual machine with attached USB devices away from the host to which the devices
are connected, the devices remain connected to the virtual machine. However, if you suspend or power
off the virtual machine, the USB devices are disconnected and cannot reconnect when the virtual machine
is resumed. The device connections can be restored only if you move the virtual machine back to the host
to which the devices are attached.

VMware, Inc. 109


vSphere Virtual Machine Administration Guide

n If you resume a suspended virtual machine that has a Linux guest operating system, the resume process
might mount the USB devices at a different location on the file system.
n If a host with attached USB devices resides in a DRS cluster with distributed power management (DPM)
enabled, disable DPM for that host. Otherwise DPM might turn off the host with the attached device,
which would disconnect the device from the virtual machine.
For additional vMotion configuration parameters and limitations for virtual machine migration, see the
Datacenter Administration Guide.

Add a USB Passthrough Device to a Virtual Machine


You can add one or more USB passthrough devices to a virtual machine. The physical devices must be
connected to the ESX/ESXi host on which the virtual machine runs.

Prerequisites
n Verify that the virtual machine is using hardware version 7 or later.
n If a USB device is connected to another virtual machine, you cannot add it until that machine releases it.
n The USB controller must be present. Add a USB controller, if needed. See “Add a USB Controller to a
Virtual Machine,” on page 109.
n Make sure that you know the virtual machine requirements for USB devices. See “USB Device Passthrough
Configuration from an ESX/ESXi Host to a Virtual Machine,” on page 104.

To use vMotion to migrate a virtual machine with multiple USB devices, you must enable all attached USB
devices for vMotion. You cannot migrate individual USB devices. For vMotion limitations, see “Configuring
USB Passthrough Devices for vMotion,” on page 109.

If you do not plan to migrate a virtual machine with USB devices attached, deselect the Support vMotion
option when you add the USB device. This reduces migration complexity, which results in better performance
and stability.

Remove a USB Device from a Virtual Machine


When you remove a USB device from a virtual machine, it reverts to the host and becomes available to other
virtual machines that run on that host.

To minimize the risk of data loss, follow the instructions to safely unmount or eject hardware for your operating
system. Safely removing hardware allows accumulated data to be transmitted to a file. Windows operating
systems typically include a "Remove Hardware" icon located in the System Tray. Linux operating systems use
the umount command.

NOTE It might be necessary to use the sync command instead of or in addition to the umount command, for
example after you issue a dd command on Linux or other UNIX operating systems.

Procedure

1 Unmount or eject the USB device from the guest operating system.
2 Right-click the virtual machine and select Edit Settings.

3 Click the Hardware tab and select the USB device.

4 Click Remove and click OK to save your changes and close the dialog box.

Remove a USB Controller from a Virtual Machine


You can remove the USB controller from the virtual machine if you do not want to connect to USB passthrough
devices on the ESX/ESXi host.

Prerequisites

Verify that all USB devices are removed from the virtual machine.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.

2 Click the Hardware tab and select USB controller.

3 Click Remove.

4 Click OK to save your changes and close the dialog box.

The controller is no longer connected to the virtual machine, but remains available to add at a later time.

Remove USB Devices from an ESX/ESXi Host


You can remove USB devices from the host if you must shut down the host for maintenance or if you do not
want those devices to be available to virtual machines that run on the host. When you detach a USB device
from the host, the device disconnects from the virtual machine.

Use caution when you remove USB devices from a host, for example, when you plan to do maintenance on
the host. The device might still be connected to a virtual machine that migrated to another host. If data transfer
is taking place, you can lose data. Also use caution when you stop or disconnect the USB arbitrator. When you
disable the arbitrator, devices connected to the virtual machine become unavailable.

Prerequisites

Make sure that the USB devices are not in use.

VMware, Inc. 111


vSphere Virtual Machine Administration Guide

Procedure
u Follow the device manufacturers instructions to safely remove the device.

When you remove the device from the host, it is no longer available to the virtual machines that run on

Troubleshooting USB Passthrough Devices


Information about feature behavior can help you troubleshoot or avoid potential problems when USB devices
are connected to a virtual machine.

Error Message When You Try to Migrate Virtual Machine with USB Devices Attached
Migration with vMotion cannot proceed and issues a confusing error message when multiple USB passthrough
devices are connected to the virtual machine and one or more devices are not enabled for vMotion.

Problem

The Migrate Virtual Machine wizard runs a compatibility check before a migration operation begins. If
unsupported USB devices are detected, the compatibility check fails and an error message similar to the
following appears: Currently connected device 'USB 1' uses backing 'path:1/7/1', which is not
accessible.

Cause

You must select all USB devices on a virtual machine for migration for vMotion to be successful. If one or more
devices are not enabled for vMotion, migration will fail.

Solution

1 Make sure that the devices are not in the process of transferring data before removing them.

2 Re-add and enable vMotion for each affected USB device.

USB Passthrough Device Is Nonresponsive


USB devices can become nonresponsive for several reasons, including unsafely interrupting a data transfer or
if a guest operating system driver sends an unsupported command to the device.

Problem

The USB device is nonresponsive.

Cause

A data transfer was interrupted or nonsupported devices are being used. For example, if a guest driver sends a
SCSI REPORT LUNS command to some unsupported USB flash drives, the device stops responding to all
commands.

Solution

1 Physically detach the USB device from the ESX/ESXi host and reattach it.

2 Fully shut down the host (not reset) and leave it powered off for at least 30 seconds to ensure that the host
USB bus power is fully powered down.

The time between when you power on the virtual machine and when it exits the BIOS and launches the guest
operating system software can be short. You can edit boot delay options to change that amount of time or to
force the virtual machine to enter the BIOS setup screen after power on.

Delaying the boot operation is useful for changing BIOS settings such as the boot order. For example, you can
change the BIOS settings to force a virtual machine to boot from a CD-ROM.

Prerequisites

VMware Tools Components


Installing VMware Tools in the guest operating system is vital. Although the guest operating system can run
without VMware Tools, you lose important functionality and convenience.

When you install VMware Tools, you install the following components:
n The VMware Tools service (vmtoolsd.exe on Windows guests or vmtoolsd on Linux and Solaris guests).
This service synchronizes the time in the guest operating system with the time in the host operating system.
On Windows guests, it also controls grabbing and releasing the mouse cursor.
n A set of VMware device drivers, including an SVGA display driver, the vmxnet networking driver for some
guest operating systems, the BusLogic SCSI driver for some guest operating systems, the memory control
driver for efficient memory allocation between virtual machines, the sync driver to quiesce I/O for
Consolidated Backup, and the VMware mouse driver.

VMware, Inc. 117


vSphere Virtual Machine Administration Guide

n The VMware Tools control panel, which lets you modify settings, shrink virtual disks, and connect and
disconnect virtual devices.

You can also use the command-line interface of the VMware Tools configuration utility in the guest
operating system to perform these tasks. See the VMware Tools Configuration Utility User's Guide.
n A set of scripts that helps you to automate guest operating system operations. The scripts run when the
virtual machine’s power state changes if you configure them to do so.
n The VMware user process (VMwareUser.exe on Windows guests or vmware-user on Linux and Solaris
guests), which enables you to copy and paste text between the guest and managed host operating systems.

On Linux and Solaris guests, this process controls grabbing and releasing the mouse cursor when the
SVGA driver is not installed.

The VMware Tools user process is not installed on NetWare operating systems. Instead, the vmwtool
program is installed. It controls the grabbing and releasing of the mouse cursor. It also allows you to copy
and paste text.

You can optionally install WYSE Multimedia Redirector, which improves streaming video performance in
Windows guest operating systems running on WYSE thin client devices.

The installers for VMware Tools for Windows, Linux, Solaris, and NetWare guest operating systems are built
into ESX/ESXi as ISO image files. An ISO image file looks like a CD-ROM to your guest operating system and
even appears as a CD-ROM disc in Windows Explorer. You do not use an actual CD-ROM disc to install
VMware Tools, nor do you need to download the CD-ROM image or burn a physical CD-ROM of this image
file.

When you choose to install VMware Tools, vCenter Server temporarily connects the virtual machine’s first
virtual CD-ROM disk drive to the ISO image file that contains the VMware Tools installer for your guest
operating system. You are ready to begin the installation process.

Limitations
VMware Tools has the following limitations:
n Shrink disk is not supported.
n For Microsoft Windows NT, the default scripts for suspend and resume do not work.
n The mouse driver installation fails in X windows versions earlier than 4.2.0.

NOTE If you do not have VMware Tools installed in your virtual machine, you cannot use the shutdown or
restart options. You can use only the Power options. If you want to shut down the guest operating system,
shut it down from within the virtual machine console before you power off the virtual machine.

Install VMware Tools on a Windows Guest


Install the most recent version of VMware Tools to enhance the performance of the virtual machine's guest
operating system and improve virtual machine management.

To determine the status of VMware Tools, select the virtual machine and click the Summary tab. The VMware
Tools label indicates whether VMware Tools is installed and current, installed and not current, or not installed.

For Windows 2000 and above, VMware Tools installs the VmUpgradeHelper tool to restore the network
configuration.

NOTE During VMware Tools installation, a Windows guest operating system might display a message
indicating that the package has not been signed. If this message appears, click Install Anyway to continue the
installation.

Managing Multi-Tiered Applications
with VMware vApp 9
You can use VMware vSphere as a platform for running applications, in addition to using it as a platform for
running virtual machines. The applications can be packaged to run directly on top of VMware vSphere. The
®
format of how the applications are packaged and managed is called VMware vApp.

A vApp is a container, like a resource pool and can contain one or more virtual machines. A vApp also shares
some functionality with virtual machines. A vApp can power on and power off, and can also be cloned.

In the vSphere Client, a vApp is represented in both the Host and Clusters view and the VM and Template
view. Each view has a specific summary page with the current status of the service and relevant summary
information, as well as operations on the service.

The distribution format for vApp is OVF.

NOTE The vApp metadata resides in the vCenter Server's database, so a vApp can be distributed across multiple
ESX/ESXi hosts. This information can be lost if the vCenter Server database is cleared or if a standalone ESX/
ESXi host that contains a vApp is removed from vCenter Server. You should back up vApps to an OVF package
to avoid losing any metadata.

vApp metadata for virtual machines within vApps do not follow the snapshots semantics for virtual machine
configuration. So, vApp properties that are deleted, modified, or defined after a snapshot is taken remain intact
(deleted, modified, or defined) after the virtual machine reverts to that snapshot or any prior snapshots.

You can use VMware Studio to automate the creation of ready-to-deploy vApps with pre-populated
application software and operating systems. VMware Studio adds a network agent to the guest so that vApps
bootstrap with minimal effort. Configuration parameters specified for vApps appear as OVF properties in the
vCenter Server deployment wizard. For information about VMware Studio and for download, see the VMware
Studio developer page on the VMware web site.

Managing Virtual Machines 10
You use the vSphere Client to manage virtual machines. With the vSphere Client, you can open a console to
the desktop of managed virtual machines. From the console, you can change operating system settings, use
applications, browse the file system, monitor system performance, and so on, as if you were operating a
physical system. You can also use snapshots to capture the entire state of the virtual machine at the time you
take the snapshot.

You can connect the vSphere Client directly to an ESX/ESXi host and work with only the virtual machines and
the physical resources available on that host. Connect your vSphere Client to a vCenter Server to manage
virtual machines and pooled physical resources across multiple hosts. Multiple vCenter Server systems can be
joined together in a vCenter Server Connected Group to allow them to be managed with a single vSphere Client
connection.

With the vSphere Client, you can access a virtual machine's desktop by launching a console to the virtual
machine. From the console, you can perform activities within the virtual machine such as configure operating
system settings, run applications, monitor performance, and so on.

Procedure

1 In the vSphere Client inventory, right-click the virtual machine and select Open Console .

2 Click anywhere inside the console window to enable your mouse, keyboard, and other input devices to
work in the console.

Adding and Removing Virtual Machines


You add virtual machines to the vCenter Server inventory through their managed hosts. You can remove
virtual machines from vCenter Server, from their managed host’s storage, or from both.

Adding Existing Virtual Machines to vCenter Server


When you add a host to vCenter Server, it discovers all the virtual machines on that managed host and adds
them to the vCenter Server inventory.

If a managed host is disconnected, the already discovered virtual machines continue to be listed in the
inventory.

If a managed host is disconnected and reconnected, any changes to the virtual machines on that managed host
are identified, and the vSphere Client updates the list of virtual machines. For example, if node3 is removed
and node4 is added, the new list of virtual machines adds node4 and shows node3 as orphaned.

142 VMware, Inc.


Chapter 10 Managing Virtual Machines

Remove Virtual Machines from vCenter Server

vSphere Virtual Machine Administration Guide

Using Snapshots To Manage Virtual Machines


Snapshots are useful when you need to revert repeatedly to the same state but you do not want to create
multiple virtual machines. With snapshots, you create restore positions in a linear process. You can also
preserve a baseline before diverging a virtual machine in a process tree.

You can use a snapshot as a restoration point during a linear or iterative process, such as installing update
packages, or during a branching process, such as installing different versions of a program. Taking snapshots
ensures that each installation begins from an identical baseline.

Understanding Snapshots
A snapshot captures the entire state of the virtual machine at the time you take the snapshot.

Snapshots are useful when you need to revert repeatedly to the same state but you don't want to create multiple
virtual machines.

A snapshot includes the following information:


n Contents of the virtual machine’s memory
n Virtual machine settings
n State of all the virtual machine’s virtual disks

NOTE VMware does not support snapshots of raw disks, RDM physical mode disks, or independent disks.

Snapshots operate on individual virtual machines. In a team of virtual machines, taking a snapshot preserves
the state only of the active virtual machine.

When you revert to a snapshot, you return all these items to the state they were in at the time you took that
snapshot. If you want the virtual machine to be suspended, powered on, or powered off when you launch it,
make sure that it is in the correct state when you take that snapshot.

While snapshots provide a point-in-time image of the disk that backup solutions can use, do not use snapshots
for your own virtual machine backups. Large numbers of snapshots are difficult to manage, take up large
amounts of disk space, and are not protected in the case of hardware failure.

Because you cannot revert to a snapshot with dynamic disks, quiesced snapshots are not used when backing
up dynamic disks.

Backup solutions, like VMware Data Recovery, use the snapshot mechanism to freeze the state of a virtual
machine. However, the Data Recovery backup method has additional capabilities that mitigate the limitations
of snapshots.

Multiple snapshots refers to the ability to create more than one snapshot of the same virtual machine.

Multiple snapshots are not simply a way of saving your virtual machines. With multiple snapshots, you can
save many positions to accommodate many kinds of work processes.

When taking a snapshot, the state of the virtual disk at the time the snapshot is taken will be preserved. When
this occurs, the guest cannot write to the vmdk file. The delta disk is an additional vmdk file to which the guest
is allowed to write. The delta disk represents the difference between the current state of the virtual disk and
the state that existed at the time the previous snapshot was taken. If more than one snapshot exists, delta disks
can represent the difference (or delta) between each snapshot. For example, a snapshot can be taken, and then
the guest could write to every single block of the virtual disk, causing the delta disk to grow as large as the
entire virtual disk.

144 VMware, Inc.


Chapter 10 Managing Virtual Machines

When a snapshot is deleted, the changes between snapshots and previous disk states are merged, and all the
data from the delta disk that contains the information about the deleted snapshot is written to the parent disk
and merges with the base disk only when you choose to do so. This can involve a large amount of disk input
and output. This may reduce the virtual machine performance until consolidation is complete.

The amount of time it takes to commit or delete snapshots depends on how much data the guest operating
system has written to the virtual disks since the last snapshot was taken. The required time is directly
proportional to the amount of data (committed or deleted) and the amount of RAM allocated to the virtual
machine.

For additional information about snapshot behavior, see the Knowledge Base article at
http://kb.vmware.com/kb/1015180.

Relationship Between Snapshots


The relationship between snapshots is like that of a parent to a child. In the linear process, each snapshot has
one parent snapshot and one child snapshot, except for the last snapshot, which has no children snapshots.

The snapshots taken form a tree. Each time you revert and take another, a branch (child snapshot) is formed.

In the snapshot tree, each snapshot has one parent, but one snapshot might have more than one child. Many
snapshots have no children.

You can revert to a parent snapshot or a child snapshot.

Snapshots and Other Activity in the Virtual Machine


When you take a snapshot, other activity going on in the virtual machine might affect the snapshot process
when you revert to that snapshot.

The best time to take a snapshot is when no applications in the virtual machine are communicating with other
computers. The potential for problems is greatest if the virtual machine is communicating with another
computer, especially in a production environment.

For example, if you take a snapshot while the virtual machine is downloading a file from a server on the
network, the virtual machine continues downloading the file and communicating its progress to the server. If
you revert to the snapshot, communications between the virtual machine and the server are confused and the
file transfer fails.

Take a Snapshot
You can take a snapshot while a virtual machine is powered on, powered off, or suspended. If you are
suspending a virtual machine, wait until the suspend operation finishes before you take a snapshot.

Prerequisites

If the virtual machine has multiple disks in different disk modes, power off the virtual machine before you
take a snapshot. For example, if you have a special purpose configuration that requires you to use an
independent disk, you must power off the virtual machine before taking a snapshot. This applies only to
snapshots taken with memory.

Procedure

1 Select Inventory > Virtual Machine > Snapshot > Take Snapshot.

2 Type a name for your snapshot.

3 (Optional) Type a description for your snapshot.

VMware, Inc. 145


vSphere Virtual Machine Administration Guide

4 (Optional) Select the Snapshot the virtual machine’s memory check box to capture the memory of the
virtual machine.

NOTE Capturing the virtual machine's memory results in a powered off snapshot, even if the virtual
machine is powered on.

5 (Optional) Select the Quiesce guest file system (Needs VMware Tools installed) check box to pause
running processes on the guest operating system so that file system contents are in a known consistent
state when you take the snapshot.

This step applies only to virtual machines that are powered on.

6 Click OK.

When you take the snapshot it is listed in the Recent Tasks field at the bottom of the vSphere Client.

7 Click the target virtual machine to display tasks and events for this machine or, while the virtual machine
is selected, click the Tasks & Events tab.

Exclude Virtual Disks from Snapshots


Deleting a snapshot involves committing the existing data on the snapshot disk to the parent disk. To exclude
a virtual disk, you change the disk mode to Independent.

Prerequisites

Power off and delete any existing snapshots before you attempt to change the disk mode.

Procedure

1 Select Inventory > Virtual Machine > Edit Settings.

2 Click the Hardware tab and select the hard disk you want to exclude.

3 Under Mode, select Independent.

The state of an independent disk is not affected by snapshots.

NOTE Any disk, regardless of its type, that is created after you take a snapshot does not appear if you
revert to that snapshot.

You have the following persistence options for an independent disk.

Option Description
Persistent Disks in persistent mode behave like conventional disks on your physical
computer. All data written to a disk in persistent mode are written
permanently to the disk.
Nonpersistent Changes to disks in nonpersistent mode are discarded when you power off
or reset the virtual machine. With nonpersistent mode, you can restart the
virtual machine with a virtual disk in the same state every time. Changes to
the disk are written to and read from a redo log file that is deleted when you
power off or reset.

4 Click OK.

Restoring Snapshots
To return a virtual machine to its original state, you can restore a snapshot.

Do one of the following:

Procedure
n The Inventory > Virtual Machine > Snapshot menu contains the command Revert to Snapshot.
n The Snapshot Manager has a Go to button.

Parent Snapshot
The parent snapshot is always the snapshot appearing immediately above the You are here icon in the Snapshot
Manager. The parent snapshot is also the most recently saved version of the current state of the virtual machine.

If you have just taken a snapshot, that stored state is the parent snapshot of the current state (You are here). If
you revert or go to a snapshot, that snapshot becomes the parent of the current state (You are here).

NOTE The parent snapshot is not always the snapshot you took most recently.

Reverting Snapshots
Reverting snapshots immediately activates the parent snapshot of the current state of the virtual machine.

The current disk and memory states are discarded and restored as they were when you took that snapshot. If
your parent snapshot was taken when the virtual machine was powered off, choosing Snapshot > Revert to
Snapshot moves the powered-on virtual machine to that parent state, that is, to a powered-off state.

If the snapshot was taken while the virtual machine was powered on and the virtual machine settings are set
to revert to snapshot when powering off, the virtual machine moves to a suspended state when it reverts to
the parent snapshot. If the no memory option is set, the virtual machine moves to a suspended state, even if
the revert operation is performed, but not through the powered-off action. If the memory option is set, the
power-off revert action puts VM is suspended state. This process is illustrated in Figure 10-1.

NOTE Virtual machines running certain kinds of workloads might take several minutes to resume
responsiveness after reverting from a snapshot. This delay may be improved by increasing the guest memory.

When you revert a virtual machine, the virtual machine returns to the parent snapshot
of the virtual machine (that is, the parent of the current You are here state).

Revert to Snapshot is a shortcut to the parent snapshot of You are here

NOTE vApp metadata for virtual machines within vApps does not follow the snapshot semantics for virtual
machine configuration. vApp properties that are deleted, modified, or defined after a snapshot is taken remain
intact (deleted, modified, or defined) after the virtual machine reverts to that snapshot or any prior snapshots.

Revert to Parent Snapshot


You can revert any snapshot to the parent snapshot state.

Procedure
u Select Inventory > Virtual Machine > Snapshot > Revert to Snapshot.

Converting Virtual Disks from Thin to Thick


You can determine whether your virtual disk is in the thin format and, if required, convert it to thick.

For more information on thin provisioning and disk formats, see ESX Configuration Guide or ESXi Configuration
Guide.

VMware, Inc. 149


vSphere Virtual Machine Administration Guide

Determine the Disk Format of a Virtual Machine


You can determine whether your virtual disk is in thick or thin format.

Procedure

1 Select the virtual machine in the inventory.

2 Click Edit Settings to display the Virtual Machine Properties dialog box.

3 Click the Hardware tab and select the appropriate hard disk in the Hardware list.
The Disk Provisioning section on the right shows the type of your virtual disk, either Thin or Thick.

4 Click OK.

What to do next

If your virtual disk is in the thin format, you can inflate it to its full size.

Convert a Virtual Disk from Thin to Thick


If you created a virtual disk in the thin format, you can convert it to thick.

The thin provisioned disk starts small and at first, uses just as much storage space as it needs for its initial
operations. After having been converted, the virtual disk grows to its full capacity and occupies the entire
datastore space provisioned to it during the disk’s creation.

Procedure

1 Select the virtual machine in the inventory.

2 Click the Summary tab and, under Resources, double-click the datastore for the virtual machine to open
the Datastore Browser dialog box.

3 Click the virtual machine folder to find the virtual disk file you want to convert. The file has the .vmdk
extension.

4 Right-click the virtual disk file and select Inflate.

The virtual disk in thick format occupies the entire datastore space originally provisioned to it.

Installing the Microsoft Sysprep Tools A
The Microsoft System Preparation tools enable you to customize Windows guest operating systems.
Using System Preparation tools is especially useful when you clone virtual machines. The guest operating
system customization feature in vCenter Server leverages the functionality of the System Preparation tools.
Ensure that your vCenter Server system meets the following requirements before you customize your virtual
machine’s Windows guest operating systems:
n Install Microsoft System Preparation tools. Microsoft includes the system tool set on the installation CD-
ROM discs for Windows 2000, Windows XP, and Windows 2003. System Preparation tools are built into
the Windows Vista and Windows 2008 operating systems.
n Ensure that the correct versions of the System Preparation tools are installed for each guest operating
system you want to customize.
n Ensure that the password for the local administrator account on the virtual machines is set to blank (““).

NOTE Customization operations will fail if the correct version of sysprep tools is not found.

This appendix includes the following topics:


n “Install the Microsoft System Preparation Tools from a Microsoft Web Site Download,” on page 153
n “Install the Microsoft Sysprep Tools from the Windows Operating System CD,” on page 154

Install the Microsoft System Preparation Tools from a Microsoft Web


Site Download
You can download and install Microsoft System Preparation tools from the Microsoft Web site.

Ensure you download the correct version for the guest operating system to customize. Microsoft has a different
version of Sysprep for each release and service pack of Windows. You must use the version of Sysprep specific
to the operating system that you are deploying.

Procedure

1 Open a browser window and navigate to the Microsoft Download Center.

2 Navigate to the page that contains the download link to the version of the tools you want.

3 Click Download and save the file to your local disk.

4 Open and expand the .cab file, using a tool such as Winzip.exe or another tool capable of reading Microsoft
CAB files.

VMware, Inc. 153


vSphere Virtual Machine Administration Guide

5 Extract the files to the provided directory.

The following System Preparation tools support directories were created during vCenter Server
installation:
C:\ALLUSERSPROFILE\Application Data\Vmware\VMware VirtualCenter\sysprep
...\1.1\
...\2k\
...\xp\
...\svr2003\
...\xp-64\
...\svr2003-64\

The ALLUSERSPROFILE is usually \Documents And Settings\All Users\. This is also the location of the
vpxd.cfg file.

Select the subdirectory that corresponds to your operating system.

6 Click OK to expand the files.

After you extract the files from the .cab file, you should see the following files:
...\guest\deptool.chm
...\guest\readme.txt
...\guest\setupcl.exe
...\guest\setupmgr.exe
...\guest\setupmgx.dll
...\guest\sysprep.exe
...\guest\unattend.doc

The guest is 2k, xp, svr2003, xp-64, or svr2003-64.

What to do next

You are now ready to customize a new virtual machine with a supported Windows guest operating system
when you clone an existing virtual machine.

Install the Microsoft Sysprep Tools from the Windows Operating


System CD
You can install the Microsoft Sysprep tools from a CD.

Procedure

1 Insert the Windows operating system CD into the CD-ROM drive (often the D: drive).

2 Locate the DEPLOY.CAB file in the CD directory, \Support\Tools.

3 Open and expand the DEPLOY.CAB file, using a tool such as Winzip.exe or another tool capable of reading
Microsoft CAB files.

154 VMware, Inc.


Appendix A Installing the Microsoft Sysprep Tools

4 Extract the files to the directory appropriate to your Sysprep guest operating system.

The following Sysprep support directories were created during vCenter Server installation:
C:\ALLUSERSPROFILE\Application Data\Vmware\VMware VirtualCenter\sysprep
...\1.1\
...\2k\
...\xp\
...\svr2003\
...\xp-64\
...\svr2003-64\

The ALLUSERSPROFILE is usually \Documents And Settings\All Users\. This is also the location of the
vpxd.cfg file.

Select the subdirectory that corresponds to your operating system.

5 Click OK to expand the files.

After you extract the files from the .cab file, you should see the following files:
...\guest\deptool.chm
...\guest\readme.txt
...\guest\setupcl.exe
...\guest\setupmgr.exe
...\guest\setupmgx.dll
...\guest\sysprep.exe
...\guest\unattend.doc

The guest is 2k, xp, svr2003, xp-64, or svr2003-64.

6 Repeat this procedure to extract Sysprep files for each of the Windows guest operating systems that you
plan to customize using vCenter Server.
