1 Background
NETLAB+ remote PCs and servers in a pod can be implemented using virtual machines
running on VMware vSphere 5.1. This guide is designed to help you setup your virtual
machine infrastructure for use with NETLAB+.
This guide assumes you are familiar with the Remote PC concept behind NETLAB+.
Please review the Remote PC Guide Series - Volume 1, Introduction and Planning for
Remote PC Implementation with NETLAB+.
This guide is designed to help you install and configure vSphere 5.1 for using with
NETLAB+. You will be installing VMware ESXi 5.1 and VMware vCenter 5.1 Server
Appliance.
This guide also assumes that you have configured the NDG supported servers, the Dell
R710, R720. Please refer to the appropriate model-specific guide:
 Remote PC Guide Series - Volume 2a - Dell R710 BIOS and RAID Configuration
 Remote PC Guide Series - Volume 2b - Dell R720 BIOS and RAID Configuration
The basics of a NETLAB+ infrastructure consist of a NETLAB+ Appliance, Management

Server, vCenter Appliance and ESXi Host Server. The following image illustrates how
these all work together:

2 VMware ESXi Planning
Physical VMware ESXi servers host the virtual machines in your pods. Virtualization
using ESXi is performed on separate physical servers, not included with NETLAB+. You
can interface with multiple ESXi servers if necessary.
NETLAB+ is compatible with VMware ESXi versions 4.1U2 and 5.1. For new installations,
version 5.1 is recommended. The hardware you use for your ESXi server(s) must be
compatible with the version of ESXi you select.
2.1 VMware ESXi Host Requirements
Please refer to our host server specifications page for the latest information on
recommended ESXi Host servers. Currently NDG supports the Dell R710 and Dell R720.
Use the following link to get detailed requirements:
http://netdevgroup.com/support/remote_pc.html#vm_host_server_specifications
Please search the VMware Compatibility guide to ensure your ESXi host hardware is
compatible with the VMware version you wish to use.
http://www.vmware.com/resources/compatibility/search.php
NDG Equipment Selection Disclaimer
NDG offers no warranties (expressed or implied) or performance guarantees (current or

future) for third party products, including those products NDG recommends. Due to the
dynamic nature of the IT industry, our recommended specifications are subject to
change at any time.
NDG recommended equipment specifications are based on actual testing performed by

NDG. To achieve comparable compatibility and performance, we strongly encourage
you to utilize the same equipment, exactly as specified and configure the equipment as
directed in our setup documentation. Choosing other hardware with similar
specifications may or may not result in the same compatibility and performance. The
customer is responsible for compatibility testing and performance validation of any
hardware that deviates from NDG recommendations. NDG has no obligation to provide
support for any hardware that deviates from our recommendations, or for
configurations that deviate from our standard setup documentation.

2.2 Hardware Assisted Virtualization Technology
Hardware Assisted Virtualization (Intel VT-x) is REQUIRED on any host you use for the
VMware IT Academy Install, Configure, Manage (ICM) course and many others.
Virtualization courses, such as the VMware IT Academy labs, have not been tested on
AMD processors and are not supported on AMD processors. VMs available from CSSIA
were created on the Intel platform. As such, they will not work correctly on an AMD
processor.
2.3 Obtaining VMware ESXi and Licenses for NDG Supported Servers – Dell
R710 and R720
If you are not using the NDG recommended host servers, the Dell R710 and Dell R720,
please skip to Section 2.4 for Obtaining VMware ESXi and Licenses for non-supported
servers.
Guidance on navigating licensing is available on the VMware Product Licensing Through

VMware Academic Subscription (VMAS) chart.
It is very important that you download the software from Dell, as they have
customized the installer ISO with drivers for the server platform, including networking
and storage adapters.

2.3.1 Downloading ESXi software from Dell
The following procedure assumes you are using a Dell R710 or Dell R720 server:
1. Go to Dell’s website at http://www.dell.com.

2. Click on Technical Support in the upper-right hand corner.
3. The easiest way is to enter your Dell Service Tag, usually found on the front of
your Dell Server. It may be on a plastic pullout (Dell R720). Enter your service
tag and click Submit.
4. If you cannot locate your Dell Service Tag, choose Servers, Storage &
Networking under choose a product category. Select PowerEdge and select your
server model, PowerEdge R710 or PowerEdge R720 respectively.
5. Click on Drivers and Downloads from the tabs listed in the middle.
6. Under Refine your results, change the Operating System to VMware ESXi 5.1.

5.1.0-799733.x86_64-Dell_Customized_RecoveryCD_A01.iso
2.3.2 Obtain licenses for VMware IT Academy Program (vITA)
Licensing considerations will vary, depending on your school's participation in the

VMware IT Academy Program (VITA) program and/or the VMware Academic
Subscription (VMAS) .


2.3.3 Obtain licenses for VMware Academic Program (VMAP)
Licensing considerations will vary, depending on your school's participation in the

VMware IT Academy Program (VITA) program and/or the VMware Academic
Subscription (VMAS) .

The following procedure assumes you are a registered member of the VMware
Academic Program (VMAP). Non-members can obtain evaluation copies of VMware
vCenter and ESXi software from http://www.vmware.com and purchase through retail
partners.
When downloading ESXi it is important to select a version that is compatible with

NETLAB+.
 NETLAB+ is compatible with VMware ESXi versions 4.1 U2 and 5.1.

 For new installations, version 5.1 is recommended.
 VMware ESXi 5.1 is a required component if you plan to use your NETLAB+
system to teach future virtualization courses.
1. Follow the link provided to you by VMware when you registered in the VMware
Academic Alliance Program. This will take you to the academic software store.
2. Click on Faculty/Staff at the top to see the available downloads. You must be a
registered Faculty/Staff user. For more information, contact the VMware
Academy contact at your school.

3. Click on VMware vSphere 5, which is marked with a red box in the picture below.
This is the first of two software items you will obtain from the e-academy
website. These items are marked with “Yes” in the picture below.

5. Sign in with your registered login if necessary.

6. Click on Check Out to continue.
7. Read and accept the EULA.

8. On the confirmation page, click on Proceed With Order.

9. On the receipt page, record the serial number found under Items. You will need
this serial number for the installation later.

2.4 Obtaining VMware ESXi and Licenses for Non-Supported Servers
If you are using the NDG recommended host servers, the Dell R710 and Dell R720,
please go to Section 2.3 for Obtaining VMware ESXi and Licenses for NDG Supported
Servers – Dell R710 and R720.
If you are using servers other than NDG’s recommendation of Dell R710 and R720, it is
strongly recommended you contact your vendor to find out if there is a customized
version of VMware ESXi needed for your hardware. The following information will point
you to the generic VMware ESXi installable ISO.
If you are part of the VMware IT Academy Program (vITA), the keys provided on the
community website are valid for VMware ESXi 5.1 installs. They also provide a link for
obtaining VMware ESXi 5.1.
If you are part of the VMware Academic Program (VMAP), please follow Section 2.3.3
for Obtaining Licenses for VMware Academic Program. That section will provide you
with the key. Perform these additional steps to download a copy of the ISO:
1. You may download the ISO image by clicking on Start Download.

2. Click the Download link for VMware ESXi 5.1 (CD ISO) Installable.

3 VMware vCenter Planning
VMware vCenter Server enables you to manage the resources of multiple ESXi hosts and
allows you to monitor and manage your physical and virtual infrastructure. Starting
with software version 2011.R2, NETLAB+ integrates with VMware vCenter Server to
assist the administrator with installing, replicating and configuring virtual machine pods.
3.1 VMware vCenter Server Requirements
As of vSphere 5.1, NDG only supports the VMware vCenter Appliance. The physical
server on which vCenter resides should be a dedicated "management server" to provide
ample compute power. It is strongly recommended you follow our server
recommendations listed below to provide ample compute power now and in the future.
http://www.netdevgroup.com/support/remote_pc.html#vcenter_server_specifications
NDG does not support configurations where vCenter is running on a heavily loaded ESXi
host and/or an ESXi host that is also used to host virtual machines for NETLAB+ pods.
Such configurations have exhibited poor performance, API timeouts, and sporadic errors
in NETLAB+ operations.
The vCenter server must have network access to your ESXi servers. You will use the
VMware vSphere Client to access vCenter Server. As of vSphere 5.1, there is a vSphere
Web Client, however this is currently not used by NDG for setup and configuration.
Below is a list of reasons why NDG will only support the VMware vCenter Server
Appliance:
 Starting with vCenter 5.1, the appliance now uses Postgres databases. This
allows the appliance to be able to handle multiple VMs and multiple ESXi hosts
compared to the 5 ESXi hosts and 50 VM limit that the vCenter 5.0 Appliance had.
 The vCenter Appliance is a standalone VM that runs on SUSE Linux, instead of
Microsoft Windows Server. This eliminates the need for Microsoft licensing for
both Microsoft Windows Server and SQL Server.
 The Windows version of vCenter 5.1 now requires multiple databases. It also
requires an Active Directory setup in order to work with the VMware Single Sign-
On feature that is embedded in the appliance. Because of the complexity of
configuring an Active Directory and multiple databases, NDG no longer
recommends nor supports the Windows version. Based on our research,
VMware is migrating to the appliance version in the future.
 The quick and easy deployment of the vCenter Appliance makes the
infrastructure configuration much easier to deploy for NETLAB+ administrators.
 NDG strongly recommends and only supports the use of the vCenter Appliance
on a separate Management Server. NDG has Management Server

recommendations that will not only support the vCenter Appliance but also
future versions of the NETLAB+ software.
3.2 Obtaining VMware vCenter Server Appliance
Follow the instructions at the following link in order to obtain the NDG Optimized
vCenter Server v5.1 Appliance OVA from CSSIA.org:
http://www.netdevgroup.com/support/documentation/CSSIA%20Preconfigured%20Virt
ual%20Machine%20Requests.pdf
When filling out the form, the "vCenter 5.1 Appliance NETLAB+ Optimized" entry is at
the bottom of the page. Be sure to select the version for ESXi 5.1 hosts.
The vCenter Server virtual appliance downloaded from VMware has a 5 host / 50 active
VM limit. We applied changes to the default vCenter Server appliance to support a
much larger 50 host / 500 VM limit, expanded the filesystem, and adjusted the RAM and
CPU settings. This optimized version has been packaged as an OVA and given to
CSSIA.org for distribution. Note, this 500 limit is active VMs and exceeds the limits of
any one NETLAB AE (80 active VM) or PE (160 active VM) system.
3.3 Obtaining VMware Licenses
Please review the following flowchart that helps with VMware product licensing:
VMware Product Licensing Through VMware Academic Subscription (VMAS)
If you are part of the VMware IT Academy Program (vITA), the keys provided on the
community website are valid for VMware vCenter Server 5 installs. They also provide a
link for obtaining VMware vSphere 5 software. You will want to obtain an OVA file of
the vCenter Server Appliance, not the ISO for installing on Windows. NDG no longer
recommends installing on a Windows machine for vCenter Server.
If you are a part of the VMware Academic Program the following procedure will assist
you in obtaining the license key as well as downloading the OVA file. You will later
deploy that image use VMware vSphere Client.
1. Follow the link provided to you by VMware when you registered the academy.
This will take you to the academic license software store.

2. Click on Faculty/Staff at the top to see the available downloads. You must be a
registered Faculty/Staff user. For more information, contact your VMware
academy contact at your school.
3. Click on VMware vCenter Server 5 Standard, which is marked with a red box in
the picture below. This is the second of two software items you will obtain from
the e-academy website. These items are marked with “Yes” in the picture below.

4. Click on Add To Cart.
5. Sign in with your registered login.

6. Click on Check Out to continue.
7. Read and accept the EULA.

8. On the confirmation page, click on Proceed With Order.
9. On the receipt page, record the serial number found under Items next to
Activation Code. You will need this code for installation later.
10. You do not need to download the vCenter Server software from this screen. You
will use the key with the NDG Optimized vCenter Server Appliance you
downloaded from CSSIA.org.
4 Network Planning
This section is designed to help you plan your networking infrastructure. Please review
the "Networking Models" section of the Remote PC Guide Series - Volume 1, Introduction

5 VMware ESXi Server Setup
This section describes the software installation on a VMware ESXi host server.
All tasks in this section are performed on separate dedicated physical servers that you
provide. Do not perform any of the tasks in this section on the NETLAB+ server
appliance, as this will delete the NETLAB+ software, requiring you to return it to NDG for
re-installation.
There should be a minimum of two (2) ESXi host servers. One will be used for
management, referred to, as the Management Server, and the other will be your ESXi
Host Server, which will hold the virtual machines for the pods. You may have one or
multiple ESXi Host servers depending on the courses you plan to teach.
NDG supports the Dell R710 and the Dell R720 as a Management Server and as an ESXi
Host Server. Please refer to the NDG requirements website for the latest supported
server configurations:

5. Repeat Steps 1-4 for each ESXi host.

6. Close the vSphere client.

9.5 vSwitch Configuration
This section is designed to configure the vSwitches on the ESXi Host Servers. To review,
a virtual switch (vSwitch) on the physical ESXi host bridges between physical networks,
virtual machines, and the ESXi host kernel. Each vSwitch is an internal LAN,
implemented entirely in software by the ESXi kernel.
Your ESXi host(s) may connect to the outside network, inside network, or both
depending on the network model you are using. The following table indicates which
virtual switches are used for outside and inside connections.
Network Model OUTSIDE vSwitch INSIDE vSwitch

Single-Homed vSwitch0 ---
Dual-Homed vSwitch0 vSwitch1

9.5.1 Verifying vSwitch0 Configuration
vSwitch0 is automatically created during the ESXi software installation (Section 5.2).
Using vCenter, confirm that networking on vSwitch0 is properly configured (refer to the
red numbered items in the screen below):
1. vSwitch0 is bound to the correct physical NIC (vmnic).

2. The physical NIC is connected and with correct speed/duplex.
3. The VMkernel port has the IP address you assigned when configuring your ESXi
host. The IP address should be a campus LAN address.

9.5.2 Inside Network Configuration
In this section, you will perform the final setup of ESXi host inside networking. This
section only applies to the dual-homed networking configuration that connects the ESXi
host(s) to the inside network (see table below). This section describes various ESXi host
networking components. We recommend reviewing this section even if inside
networking is not used in your ESXi host configuration.
Networking Configuration Inside Networking

Single-Homed Networking No
Dual-Homed Networking Yes
Repeat the setup tasks in this section for each ESXi host in your Virtual Machine
Infrastructure

There is only one type of network traffic can flow across the ESXi inside network
connection, remote PC traffic between virtual machines and real equipment (VLANs 100
- 899).
The following diagram and table describes the various components of inside networking.
# Component Description
1 ESXi Host The physical server where, your virtual machines run.
2 Inside Physical NIC The physical network interface on the ESXi Host (1) that connects
virtual machines to the inside physical network.
3 vSwitch A virtual switch on the physical ESXi host that bridges between
physical networks (2,8,9), virtual machines (7), and the ESXi host
kernel (4). Each vSwitch is an internal LAN, implemented entirely
in software by the ESXi kernel.
4 Kernel Port A virtual network interface on the ESXi host (1) that provides
connectivity between the ESXi host kernel and other components
such as NETLAB+.
5 Virtual Network Adapter (vNIC) A virtualized networking adapter inside of a virtual machine that
connects the virtual machine to a virtual switch.
6 Port Groups A template for creating virtual network switch ports with a
particular set of specifications. A port group allows a virtual
network adapter (5) to be placed in a particular virtual LAN
(VLAN). Port groups with specific VLAN IDs to connect virtual
machines to real equipment.

7 Virtual Machines In NETLAB+, a virtual machine is a remote PC or remote server

that runs on virtualized hardware. Although the hardware is
virtualized, real operating systems and real application software
can still be used.
8 Uplink / Trunk An uplink is a physical connection between ESXi Host (1,2) and a
NETLAB+ control switch (9). If you are interfacing with real
equipment pods (i.e. Cisco Networking Academy), your ESXi
inside physical interface and the control switch port to which it is
connected are configured in 802.1q trunk mode. Trunks allow
multiple virtual LANs (VLANs) to exist on a single physical
connection. VLAN assignments and the VLAN database on the
control switch are managed by NETLAB+.
9 Control Switch A NETLAB+ control switch provides connectivity between the
NETLAB+ server, ESXi host servers, asynchronous access
servers, and switched outlet devices. Control switches are not
accessed by lab users. There are three types of ports: reserved,
assigned, and unassigned.
An NDG supported control switch is required. See the NDG

website for a list of supported control switches.
10 NETLAB+ Inside Connection The NETLAB+ server inside interface connects to a designated
reserved port on a control switch (9). The fixed addresses
169.254.0.254/24 and 169.254.1.1/24 are assigned to the inside
interface (these cannot be changed).
802.1q trunk mode should NOT be enabled on the control switch

port for this connection.
11 Real Equipment Pods Real lab equipment (optional) is connected to one or more control
switches (9).
12 Reserved Ports Reserved ports are ports on a control switch (9) that are reserved
to provide connectivity between the NETLAB+ server, ESXi host
servers, asynchronous access servers, and switched outlet
devices.

The following table summarizes the traffic types that will flow over the ESXi inside
network.
Management Remote
802.1q
Networking Configuration Traffic Display
Trunk
(VLAN 1) (VLAN 1)
Single-Homed Networking n/a n/a n/a
Dual-Homed Networking No No Real Gear*
* ESXi interface and corresponding control port is configured as 802.1q trunk when
interfacing with real equipment.
9.5.3 Creating vSwitch1 and Binding to Physical NIC
If your ESXi host is dual-homed (connected to both outside and inside networks), you
must create an inside virtual switch (vSwitch 1), bind a physical NIC to vSwitch1, and
create a VMkernel port for management traffic. These tasks are performed through
vCenter.
1. Login to vCenter using the vSphere client.

2. Navigate to Home > Inventory > Hosts and Clusters.
3. Click on the ESXi host to configure in the left sidebar.
5. Click on Networking in the Hardware group box.
6. Click on the Virtual Switch view button if not already selected.
7. Click on Add Networking.

8. Add a VMkernel port to allow the ESXi host kernel to communicate with the
inside network. Select the VMkernel radio button, and then click Next.
9. Select the "Create a virtual switch" radio button. The new switch will be named
vSwitch1.
10. Select the physical NIC that will connect vSwitch1 to the control switch. We
recommend using vmnic1 for inside connections (vmnic0 should already be
connected to the outside network).

11. Enter the port group properties as shown above.

a. Network Label: "NETLAB Inside"
b. VLAN ID: None(0) (default)
c. Check option "Use this port group for management traffic"
12. Click Next.
13. The VMkernel IP Connection Settings dialog appears.
14. Enter a unique inside IP address and subnet mask from the following table.
Inside Interface IP Address Subnet Mask

ESXi Server 1 Inside 169.254.0.241 255.255.255.0


No changes to the VMkernel Default Gateway setting should be necessary. This should
already be set to the default gateway on your campus LAN.

16. Confirm that vSwitch1 appears as follows (IP varies for each host).
a. VMkernel port (vmk1) has correct IP address.
b. vSwitch1 is bound to physical adapter (vmnic1)
c. Physical adapter is up (speed and duplex are detected)
A mark displayed near the Physical Adapter indicates that the connection has not yet
been physically cabled or the corresponding control switch port is shut down.

9.5.4 Increasing the Inside vSwitch Port Count
By default, a vSwitch is provisioned with 56 virtual ports. This means that 56 virtual
network adapters can be connected to the virtual switch, regardless of which port group
the adapter is connected. For most NETLAB AE setups, this is sufficient for the inside
vSwitch. For large NETLAB PE setups or systems with custom real equipment pods, you
may need to increase this value to accommodate more virtual machine connections to
the inside vSwitch.
This discussion applies to virtual machines that are part of real equipment pods. Pods
that contain only virtual machines are usually placed on separate vSwitches that do not
connect to the inside network / real equipment.
To calculate the number of inside vSwitch ports required on a particular ESXi host, add
up the number of virtual machines in real equipment pods that are assigned to the host.
This is the number of virtual ports required on the inside vSwitch (assuming one
connection per VM). If this number exceeds 50, you should select the next highest port
count setting (120). In special cases, an even higher setting may be required. Note: 50
is not an error; 6 extra ports were subtracted (from 56) to allow for VMkernel ports and
other possible connections. Higher port count settings consume additional host
resources, so you should set this value to the lowest possible setting that provides
enough ports for every virtual machine connecting to the inside vSwitch.
There is no warning when the number of virtual ports is exceeded and the problem is
not obvious. Some of the virtual machines will fail to communicate for no apparent
reason. The only clue may be a disconnected network status from the guest operating
system.
The following procedure is used to increase the number of virtual ports on the inside
virtual switch. The same procedure can be used on any virtual switch should the need
arise.
1. Login to vCenter using the vSphere client.

2. Navigate to Home > Inventory > Hosts and Clusters.
3. Click on the ESXi host where the pod's virtual machines will run.
5. Click on Networking in the Hardware group box.
6. Click on the Virtual Switch view button if not already selected.

7. Click Properties on the INSIDE vSwitch. The inside vSwitch is the one that is
connected to the control switch (vSwitch1).
8. Click on the vSwitch configuration item.

9. Click the Edit button.

10. Increase the number of ports, but not higher than needed.
11. Click OK.
The ESXi host must be restarted for the change to take effect. Make sure there are no
active NETLAB+ reservations that affect this host, or virtual machines running on this
host as user work may be affected.
12. Right click on the ESXi host in the left sidebar to activate the context menu.
13. Select Reboot.

9.5.5 Create a Safe Staging Network
In this section, you will be creating a Safe Staging Network called “safety net”, to
temporarily connect our VMs. The Safe Staging Network consists of a virtual switch and
a port group that is not connected to any other networks (virtual or real). Should the
virtual machine be powered on, its traffic will be confined to the safety net. This
ensures that the virtual machine will not pose a security risk to your campus LAN or
interfere with other pods, until it is relocated to its final network via automatic or
manual networking.
1. Select your first ESXi host in the Inventory pane on the left.
3. In the Hardware box click on Networking. Then click on the Add Networking…
hyperlink to create a new virtual switch.

4. On the Connection Type page, select Virtual Machine and click Next.
5. On the Network Access page, select Create a vSphere standard switch and click
Next.
UNCHECK any vmnics under the radio button; this virtual switch should not be
bound to any real network adapters on the ESXi host.

6. On the Connection Settings page, enter SAFETY NET in the Port Group’s
Network Label property and then click Next.
7. On the Summary page, review the information and click Finish.

8. Repeat steps 1-7 for each ESXi host server.
SAFETY NET is now available for use as a safe temporary network location for new
virtual machines.
The safety network is an ideal place to bind the network interface(s) of master
virtual machines. Automatic networking will the bind network interfaces of cloned
VMs to their runtime networks when their respective pods are started.
