System Requirements
2
This chapter describes everRun configuration basics, as well as the hardware, software,
disk space, and network requirements for the system.
Basic everRun Configuration

Figure 2-1 shows a schematic of a basic everRun configuration, which is a resource
pool containing two XenServer hosts and a separate management computer.
Figure 2-1 A basic everRun configuration is a pool of two XenServer hosts that
can support virtual machines, as well as a general-purpose PC that
can run both the XenCenter management application and the
browser-based everRun Availability Center management client.
System Requirements 5
The XenServer software must be installed on two x64 (64-bit) servers, which are known
as the XenServer hosts. The XenServer hosts are dedicated to the task of hosting
virtual machines (VMs). All hosts must be members of the same XenServer
resource pool.
The management computer that runs the XenCenter management application and
the browser-based everRun Availability Center (eAC) management client can
run on any general-purpose Windows machine that satisfies the hardware
requirements. This computer can also be used to run other Windows applications.
If the resource pool contains more than two XenServer hosts (using point-to-point cable
links), or if the hosts in the pool are geographically separated (as in a SplitSite®
deployment), two quorum service computers must be connected to the network, as
described in the everRun Configuration Planning Guide.
Hardware Requirements
The hardware requirements are based on those given in the XenServer Installation
Guide. A list of hardware and software components that have been reported to work
with XenServer, as tested by Citrix, by the individual vendors, or by the Xen
community, is available at http://hcl.xensource.com/ .
For the most reliable operation, choose components tested by Citrix or by the individual
vendors.
XenServer Hosts
Each XenServer host is an x64 server-class machine devoted to hosting multiple VMs.
This machine runs a customized distribution of the Linux operating system, with a
XenServer-enabled kernel that controls the interaction between the virtualized devices
accessible by VMs and the physical hardware.
Table 3 lists the requirements for each system host. The processors in each host must
support hardware virtualization, as shown in the CPU row of the table.
Table 3: Requirements for XenServer Host Computers
Category Requirements
CPUs One or more x64 CPUs, 1.5 GHz minimum, 2 GHz or faster multicore
CPU recommended. For VMs running Windows, the processors must be
virtualization-capable Intel models with one or more (up to 32) CPUs.
A second computer with identical processors is required for use as a
redundant server for everRun PVMs. The CPUs for every XenServer
host computer must have hardware support for virtualization enabled
in the BIOS.

CPUs For a list of processors supported by Marathon products (required for

(cont.) Level 2 and Level 3 protection, for example), see
http://www.marathontechnologies.com/documents/
Hardware_Qualifications.pdf
If you are not certain whether your hardware supports everRun
operation, download the everRun_CompatibilityCheck utility,
available in the Tools and Utilities section of the Marathon customer
web portal. Download the Compatibility Check Readme document, also
at the web site, for instructions.
Supported Guest VMs may run any OS listed in the XenServer documentation.
guest OS
Guests that are candidates for everRun protection must be running
Windows Server 2003 Standard or Enterprise (32- or 64-bit, SP2) or
Windows Server 2008 Standard or Enterprise (64-bit, SP1 or SP2).
RAM 2 GB minimum, 4 GB or more recommended.
Disk space Locally attached storage (PATA, SATA, SCSI, or FC-SAN) with a
for storage minimum of 72 GB of total disk space recommended. Shared storage
repositories (NFS share, iSCSI, and FC-SAN as described in the
XenServer Installation Guide) are also supported.
Disk space • 4 GB for XenServer in the host control domain, Domain0
required (Dom0),and 4 GB for everRun in a supported storage repository
(SR).
• Allow 10 GB minimum (Windows boot disk) for each Windows VM.
This may be located in local attached storage or shared storage, as
described under “Disk space for storage” above.
• Additional storage as required for applications and data on each VM.
Network For optimum performance and reliability, Marathon recommends five
1 GB network interface cards (NICs), with network switches to provide
separate network channels, if necessary. If possible, use identical NICs.
IP Each XenServer host must have a static IP address assigned for use by
Addresses the management software. Obtain IP addresses for DNS primary and
secondary servers, as well as gateway and subnet mask information for
your management network, from your IT network administrator.
Ports XenCenter uses port 443 in the local firewall for HTTPS
communications, port 22 for ssh, and 5900 for VNC with Linux VMs.
Make sure your firewall allows traffic via the appropriate ports.
The eAC uses TCP ports 8080 and 8081 for communication, but you can
change these defaults. (See Appendix A for more information.)
Firewalls must permit everRun protected VMs to contact quorum

service computers using UDP port 2189, and quorum service computers
to contact everRun-enabled XenServer hosts using UDP port 2188.
Management and Quorum Service Computers

The management computer can support the two management interfaces that control
the everRun system:
• the XenCenter GUI that controls XenServer software
• the everRun Availability Center (eAC) GUI
XenCenter, the client application for remote management of XenServer hosts, can be
installed and run on any XP/Vista workstation or laptop.
The browser-based eAC everRun management GUI can be loaded and run by a Flash-
enabled web browser on any computer, including the management computer. Table 4
shows the system requirements for the management computer.
NOTE: The everRun eAC GUI requires management network access and a compatible
Flash-enabled browser. If you are running a 64-bit operating system on this
computer, use a Flash-enabled 32-bit browser to access everRun. (At the time
of this release, 64-bit browsers do not support Adobe Flash Player.)

System Configuration
and Setup 3
This chapter describes a basic, local two-host XenServer pool. For details on other
deployment options, refer to the everRun Configuration Planning Guide.
Local Two-Host everRun Pool

everRun software runs as a turnkey application in a XenServer virtual environment.
Figure 3-1 illustrates a basic two-host setup with four networks.
Figure 3-1 Two private networks called availability links (A-links)

synchronize and maintain redundancy between the components of
two XenServer hosts. Separate network adapters connect the hosts to
the production LAN and to the management LAN.
System Configuration and Setup 11

The two servers in Figure 3-1 also contain two directly cabled A-link connections. The
everRun Configuration Planning Guide guide describes this configuration in greater
detail.The guide also includes more complex configurations — having two or more hosts
—that require active, switched networks. In a switched configuration, additional
quorum service computers, running on separate subnets, coordinate the
redundant everRun software running on the two physical hosts.
The two interconnected XenServer hosts shown in Figure 3-1 are members of the same
XenServer resource pool. In the recommended configuration, Host 1 is designated
the master host and Host 2 is the member host. A separate, general-purpose
management computer with access to the management LAN contains the
XenCenter management console and provides browser access to the everRun
Availability Center (eAC) client.
NOTE: In Figure 3-1, the configuration shows four networks that use five NICs. The
fifth NIC is used to create a bonded management LAN, as recommended when
you plan to enable XenServer High Availability (HA). This bonded NIC is not
required for the everRun evaluation deployment, or any configuration that
does not include XenServer HA.
Step 1: Plan Your Configuration, Obtain Components

The everRun Configuration Planning Guide provides information to help you select the
everRun deployment most suitable for your needs, obtain qualified components, and
assemble the physical system. If you require assistance in customizing the deployments
described in that guide, consult Marathon Professional Services.
Step 2: Download Software and Documentation

Download instructions are included with your email from Marathon Order
Administration.
In each everRun release you must check the everRun Release Notes to determine what
version of the Citrix XenServer software, and what updates to that software, are
required for the release. Only the updates identified in the everRun documentation
should be installed.
You can download the ISO images for both the Citrix software and the Marathon
software from the Marathon download site or you can obtain the Citrix software from
other sources.
Note that the Citrix XenServer download area contains two ISO images: the XenServer
Product CD Image (ISO) and the XenServer Linux Guest Support CD Image (ISO). The
XenServer Product CD Image is required for the everRun installation, but the
XenServer Linux Guest Support CD Image is not. However, you may want to download

both ISO images to obtain the complete XenServer distribution. (In that way, you can
burn a Linux CD to create virtual machines that do not use everRun.)
In addition, you will need the license information obtained when you acquired
XenServer and everRun.
Installation Alternatives
This guide documents two alternative procedures to use for everRun installation:
• Installation from a CD-ROM drive attached to your management computer
• Installation from a shared directory on your management computer
CD-ROM Method
Use this method throughout the install process if you want to create CD-ROMs
containing the XenServer and everRun ISO images, then insert that CD-ROM into a
drive on the XenServer management computer (the computer that contains the
XenCenter software) to install the software on each XenServer host in the pool.
To prepare for installation using a CD-ROM:
1. Use any web browser to download the Citrix and Marathon ISO images to the
XenCenter management computer.
2. After downloading the files, use your company’s commonly accepted methodology
to save the ISO images onto three bootable CD-ROMs — two for the Citrix ISOs,
and another for the Marathon everRun ISO.
NOTE: The Citrix software requires a separate CD for the Linux VM templates. These
templates are used by the XenServer product, but not by everRun.
You will also need to store your Citrix and Marathon license information in a
directory on your management computer that is accessible to the XenServer hosts.
Note the directory name for later use.
Shared Directory Method

Use this method throughout the install process if you want to create a shared directory
on the Windows management computer and then run the installers from that directory.

To prepare for installation using a shared directory:
1. Create a shared directory on the management computer, using the standard

Windows procedure for sharing a drive or folder on the network.
2. Download the Citrix and Marathon ISO images to the shared directory on the
XenServer management computer using your favorite web browser.
If you wish, you can add license files or other relevant material to this directory.
You will also need to store your Citrix and Marathon license information to a location
on your management computer that is accessible to the XenCenter. Note the
directory name for later use.
NOTE: This procedure requires that you install the XenServer software on the master
and member hosts over a network. Refer to the XenServer Installation Guide
appendix entitled “PXE installation of XenServer host” for more information.
Step 3: Set Up the XenServer Environment

You must set up a running XenServer environment before you install the everRun
software. You will install XenServer software on each host and install the XenCenter
management application on a separate Windows management computer.
Set Up XenServer Hosts

A XenServer resource pool requires a minimum of two physical servers with Intel
hardware virtualization technology. This section contains instructions for setting up
the local area networks, storage repositories, and XenServer environment for the pool.
NOTE: To run Windows VMs, the XenServer host must have hardware support for
virtualization enabled in the BIOS. This option is normally disabled by default.
Check your BIOS settings before you install the XenServer software.
Define the Network Configuration

Set up the basic configuration shown in Figure 3-1; it contains four LANs that use five
physical network interface cards (NICs) on each server.
NOTE: Do not use DHCP to set up the XenServer hosts. Instead, use the static IP
addresses you obtained from your local IT administrator.

The management LAN uses two NICs to create the bonded NIC.) This section describes
the recommended network configuration for the basic deployment supported in this
release.
NOTE: Remember, if you do not plan to use XenServer HA, you do not need to create
a bonded NIC for the management network.
Marathon recommends the following network assignments:

• eth0 — XenServer management LAN
The system management LAN provides connectivity to the XenServer hosts for
clients running the XenCenter management application and the Marathon’s
everRun Availability Center (eAC) management software. Choose eth0, as
recommended in the XenServer Installation Guide.
• eth1 — availability link 1
Availability link 1 (A-link 1) is a direct-cabled, or an active, switched network
connection from eth1 on one host to eth1 on a second host.
• eth2 — availability link 2
Availability link 2 (A-link 2) is a second direct-cabled, or an active, switched
network connection from eth2 on one host to eth2 on the second host.
• eth3 — production LAN
This is the network used to provide connectivity from application clients to
applications operating on virtual machines resident on the XenServer hosts.
• eth4 (optional) — bond with eth0, XenServer management LAN
If you are planning to employ XenServer HA, you can use this NIC to create the
bonded NIC for the XenServer management LAN, as described in “(Optional)
Create a NIC Bond on the Master Host” on page 20.
XenServer automatically creates a virtual bridge called a Xen bridge (xenbr), which
is named to correspond to each Ethernet adapter during XenServer installation. The
XenServer convention names xenbr0 to provide a virtual bridge to eth0, xenbr1 to
provide a virtual bridge to eth1 and so forth. When you configure networks for use by
the virtual machines or everRun software, you can refer to the corresponding virtual
bridge name to understand the physical path connectivity. For more information, see
the XenServer documentation.
Define the Storage Configuration

The configuration shown in Figure 3-1 can use local storage attached to each of the
XenServer hosts or it can use shared storage based on NFS, iSCSI, fibre channel (FC)
SAN, NetAPP® etc.

Use the instructions for setting up local and shared storage in the relevant
sections of the XenServer Installation Guide.
NOTE: For a basic discussion of how physical storage hardware is mapped to VMs in
XenServer, see the XenServer Administrator’s Guide.
Install the XenServer and XenCenter Software

After you have attached the network and storage devices to the network, you are ready
to install the XenServer and XenCenter software. To ensure a successful XenServer
setup, perform the following tasks in the sequence listed:
• Install the XenServer software on the first host (the master host).
• Install the XenServer software on the second host.
• Install XenCenter software on the management computer.
• Activate the XenServer software as requested, or, if you are using Citrix
Essentials, use XenCenter to apply a XenServer license to each host.
Instructions for each of these tasks are given in the following sections.
Install XenServer Software on the XenServer Hosts

Follow instructions in the XenServer documentation to install the XenServer software
on each XenServer host.
NOTE: As you install, remember that XenServer hosts require static IP addresses in
order to be included in a XenServer pool.
To install XenServer using a CD-ROM:
1. Load the installation CD you created after download into the CD-ROM drive of
XenServer Host 1 (the master host). Follow the installation instructions in the
XenServer Installation Guide, setting eth0 as the XenServer management
network.
2. Install the XenServer software on the additional host(s). Again follow the
installation instructions in the XenServer Installation Guide, setting eth0 as the
XenServer management network.
3. If you are installing additional hosts, repeat step 2 on each member host in the pool.

To install XenServer using other bootable media:
NOTE: The XenServer software cannot be installed from a shared directory. You can
use any bootable medium or use the PXE boot instructions documented in the
XenServer Installation Guide.
1. Transfer the downloaded Citrix ISO to other bootable media, then install the
software on the master XenServer host. Follow the installation instructions in the
XenServer Installation Guide, setting eth0 as the XenServer management
network.
2. Install the XenServer software on the other host(s) in the pool. Again follow the
installation instructions in the XenServer Installation Guide, setting eth0 as the
3. If you are installing additional hosts, repeat step 2 on each member host in the pool.
Install XenCenter Software on the Management Computer

Before you install the XenCenter software, use the Windows Add or Remove Programs
option on the Windows Control Panel to remove any previous version of XenCenter, as
recommended by Citrix XenSource.
To install XenCenter using a CD-ROM:
1. Put the XenServer CD you created from the Citrix ISO file into the CD drive of your
management computer.
If Auto-play is enabled for the CD drive, the XenCenter installer launches
automatically after a few moments.
If Auto-play is not enabled for the CD drive, browse to the \client_install
directory on the CD and find the file named XenCenter.msi. Double-click on the
file icon to launch the XenCenter installer.
2. Follow the instructions displayed in the installer window. When prompted for the
installation directory, either click Browse to change the installation location, or
click Next to accept the default path C:\Program Files\Citrix\XenCenter.
To install XenCenter using a shared directory:
1. If you are installing from a shared directory, browse to the \client_install

directory within the XenServer file structure and find the file named
XenCenter.msi. Double-click on the file icon to launch the XenCenter installer.
2. Follow the instructions displayed in the installer window. When prompted for the
installation directory, either click Browse to change the installation location, or
click Next to accept the default path C:\Program Files\Citrix\XenCenter

Connect to XenServer Hosts and Install Licenses
As noted in the XenServer Installation Guide, Citrix XenServer is available for free
production use with no restrictions or time limits. All you need to do is activate the
product within 30 days of installation, and then again on an annual basis. If you want
to add more advanced features, you can upgrade to Citrix Essentials via a license key,
with no additional software installation.
If you do add a license, you should first connect in XenCenter to the server you want to
use as the pool master host and install a XenServer license on that host. The license file
should be on the management computer, in the directory where you stored it after
obtaining it from your software provider. After you have licensed the first host, you will
be able to connect to and add a license to additional XenServer host(s).
To connect to a XenServer host and apply a license:
1. Click the Add New Server icon at the top left.
2. When the Add New Server dialog box opens, enter the server IP address of
XenServer Host 1 in the Hostname field, then enter the user name and password
you created when you set up the server and click Connect.
3. To add the XenServer license, open the XenCenter Server menu and choose the
Install License Key command.
4. Browse to the directory where you saved the license file.
5. Double-click the *.xslic license file. XenCenter automatically applies the license.
6. Repeat steps 1-5 to apply a license to any other XenServer hosts in the pool.
Step 4: Create a XenServer Resource Pool

To complete your XenServer setup, add each host to a resource pool that contains a
master host and a member host (sometimes called the “slave” in CLI commands). Then
use the XenCenter console (or any console window) to verify the network connections
on both hosts.
Add the Master Host and Member Host(s) to a Pool

In the XenCenter Online Help, open the Help Contents and follow instructions in
“Working with resource pools,” “Creating a pool,” and “Adding a server to the pool.”
Verify Network Connections

To verify your XenServer setup, take a moment to verify your network connections.
This step is critical to the success of an everRun installation.

XenServer software uses PIF objects to represent physical network interfaces. As
explained in the “NIC/PIF Ordering in Resource Pools” section of the Networking
chapter of the XenServer Administrator’s Guide, you can use XenServer xe commands
to review the MAC address and carrier (link state) parameters associated with each
PIF and to verify that the devices discovered (eth0, eth1, etc.) correspond to the
appropriate physical port on the server.
Use two commands for this task. First use xe pif-list to get the UUID (user ID) of
the PIF you want to verify. Then use xe pif-param-list and the PIF UUID to
identify which connector controls each network. You can run these commands from the
console command line in XenCenter or from any remote console that can access the
XenServer hosts.
As you verify each network cable, you may want to label the associated port with the
network name, or create a simple table that lists the network connectivity for each port.
To get the UUID of a network PIF:
1. With all cables connected to your system, select a XenServer host in the XenCenter
resource pane, then issue the following command in XenCenter to obtain network
UUIDs:
# xe pif-list
You will see a display that looks something like this:
uuid ( RO) : 5b430bc0-d4fd-098f-5d33-4f9cbf84c4a4
device ( RO): eth0
currently-attached ( RO): true
VLAN ( RO): -1
network-uuid ( RO): 7a002152-ed55-bbfe-01a9-1aa4c24cea1b
uuid ( RO) : b7f1fae1-911f-5305-60be-cbeccf801127
device ( RO): eth2
VLAN ( RO): -1
network-uuid ( RO): df6b1575-4b72-b606-458b-67dd06e222db
uuid ( RO) : efbd710d-dba8-75a4-d024-8479fd81dd4e

device ( RO): e*h1
VLAN ( RO): -1
network-uuid ( RO): 67b4ee16-390b-b947-a604-5e760fd3eb31
2. Use this display to cut and paste each UUID you want to verify, as shown in the
following sequence.

To verify the connectivity of your networks:
1. With the cables still attached, look at the parameters for the network identified as
eth0 by issuing the following command using the UUID for eth0:
# xe pif-param-list uuid=5b430bc0-d4fd-098f-5d33-4f9cbf84c4a4
param-name=all
XenServer returns a long list of parameters associated with that UUID.
uuid ( RO) : 5b430bc0-d4fd-098f-5d33-4f9cbf84c4a4
device ( RO): eth0
MAC ( RO): 00:1e:4f:f5:7f:7e
physical ( RO): true
etc...
2. Scan down the list to find the carrier parameter:

carrier ( RO): true
The value of true indicates network connectivity.
3. Now remove the cable from eth0 and issue the command again:
# xe pif-param-list uuid=5b430bc0-d4fd-098f-5d33-4f9cbf84c4a4
param-name=all
XenServer should return the following parameter set:
: 5b430bc0-d4fd-098f-5d33-4f9cbf84c4a4
device ( RO): eth0
MAC ( RO): 00:1e:4f:f5:7f:7e
physical ( RO): true
etc...
carrier ( RO): false
The value of false indicates the network is not connected.
Repeat the sequence for each of the network PIFs (eth1, eth2, eth3...) to verify
that the physical cable corresponds to the network
IP addresses are not available for all networks at this time. When the information
becomes available, you may want to add it to your table. The information will be useful
if you need to modify or troubleshoot the networks later on.
(Optional) Create a NIC Bond on the Master Host

If you plan to enable XenServer HA, it is highly recommended that your network
configuration contain five NICs, including a bonded NIC on the XenServer
management network as described in “Define the Network Configuration” on page 14.
The XenServer software uses NIC bonding to provide resiliency of the management
network for Level 1 (XenServer High Availability or HA) protection.

To create a bonded NIC on the master host:
1. Highlight the master host and click the NICs tab.

You should see five networks, with NICs numbered 0 to 4.
2. Click the Create Bond button.
3. Choose NIC 0 from the Available NICs box at left, then click the Add > button to
move NIC 0 to the Bonded NICs column
4. From the list of available NICs, choose NIC 4, and click the Add > button to move
NIC 4 to the Bonded NICs column.
5. Click Create.
During bonding, a progress bar displays in the lower-right corner of your screen.
Wait for it to complete.
When you create a NIC bond on the pool master host, the bond should replicate to the
pool member host(s). However, you should check to make sure the bonded network on
the member host is connected, as described in the following process.
To check the status of the network on the member host:
1. In the XenCenter resource pane, select the member host.
2. Click the Networks or NICs tabs to see if the bonded NIC displays as Connected.
3. If it is not connected, use the following steps to connect:

– Right-click the member host and select Management Interfaces.
– From the list of interfaces, choose 0+4 bonded.
4. Click Finish to apply the bonded interface.
Step 5: Check for XenServer Updates
NOTE: Do not install any XenServer updates that are not identified in the everRun
Release Notes for the current release. If you have any questions about an
update, contact your Marathon support provider.
XenCenter provides facilities for updating the XenServer software, as required in some
releases. You must have an active Internet connection in order to locate and download
updates.

To download and install the required XenServer updates:
1. Check the everRun Release Notes to see if any Citrix XenServer updates are
required for the current release. In some cases, updates may not be required.
2. If updates are required, use the processes described in the XenCenter Online Help
(use Help > Check for Updates) to download any required updates, and to install
them onto the pool master host and member host.
NOTE: If you apply XenServer update(s) manually, remember to reboot the server in
order to apply the update. If you proceed without doing this, the update will not
be available on your system. If you choose the Automatic option, the reboot is
performed automatically.
Step 6: Create Windows Guest Virtual Machines

Now you can create one or more Windows virtual machines (VMs) and install the
XenCenter tools on those VMs. Use the XenCenter GUI and the XenServer
documentation listed in the following procedure.
To create a new guest VM and install the XenServer tools:
1. Open the VM menu at the top of the XenCenter interface and choose the New
command to display the Create VM wizard. See the XenCenter Online Help topics
under “Working with VMs” for instructions on installing and configuring a guest
VM.
2. Use appropriate Windows installation media to install the operating system on the
new VM.
3. See the XenCenter Online Help topic “Working with VMs > Installing XenServer
Tools” for instructions on adding the required drivers on each VM.
TIP: To determine whether the XenServer tools have been installed, highlight a VM
in the XenCenter resource pane and open the General tab. If the tools are
required for that VM, a red Tools not installed message displays.
4. See the XenCenter Online Help topic “Working with VMs > Configuring Virtual
network interfaces” for instructions on adding a network to your VM.
NOTE: If you are creating a new VM, you must install the Windows operating system
and the XenServer tools on the VM. A VM imported from a template may
already have Windows and the XenServer tools installed on it.

Additional topics in the XenCenter Online Help describe alternatives to creating a new
VM: using templates, copying a VM, or importing a VM.
Step 7: Install Your Windows Applications

You can install applications on your Windows VMs before or after installing and
configuring everRun.
Next: Installing Marathon Software

You can install the everRun software (and quorum service software, if used) before or
after you create XenServer VMs or install Windows applications. In general, however,
it is recommended that you establish a reliable XenServer environment— including a
resource pool — before you install everRun.
In Chapter 4, follow the step-by-step instructions for loading the everRun software (and
quorum service software, if used), accessing the everRun Availability Center, and
installing the everRun license on the resource pool.

Installing the
everRun Software 4
This chapter provides instructions for installing everRun in your XenServer

environment. Then it describes how to open the everRun Availability Center (eAC), the
everRun management client, and install the everRun license.
NOTE: This chapter describes the remaining steps of the installation process in terms
of the default options. If you would like to change any installer options, refer to
Appendix A, “everRun Installer Online Help”.
Preparing to Install everRun

For the final installation steps you will need to use either the everRun CD-ROM created
after downloading the everRun software kit from the Marathon web site or the shared
directory that contains the downloaded ISO files.
Accessing Dom0 from the Management Computer

The CD or shared directory contains the everRun installer file, everRun-5.1.1SP-
installer.bin. To execute this binary file in Dom0 on each XenServer host, you can
do one of the following:
• Mount the CD in a location that is visible to Dom0, then use the host console in
XenCenter to run the install binary.
• Mount the shared directory in a location that is visible to Dom0, then use the host
console in XenCenter to run the install binary.
By connecting to your XenServer host from XenCenter, you created a link to Dom0 on
the XenServer host. This section describes how to open a command-line interface so you
can run the everRun installer in Dom0.
Installing the everRun Software 25

To connect to Dom0:
1. Highlight the XenServer host name in the left panel (the resource pane) of the
XenCenter interface.
You will see a series of tabs to the right.
2. Click the Console tab to open a command-line interface where you can access Dom0.
Step 8: Using the everRun Installer Wizard

First install the everRun software on XenServer Host 1 (the master host), then repeat
the process to install it on the XenServer member host. The master host must be
running when you install the software on the member host.
To start the wizard using a CD-ROM:
For this alternative you need the CD you created from the Marathon ISO image. The
CD contains the everRun installer file, everRun-5.1.1SP-installer.bin. To
execute this binary file from Dom0 on the XenServer host, you mount the CD in a
location that is visible to Dom0, then use the host console in XenCenter to run the
install binary.
The following instructions explain how to create a CD mount point by typing a simple
Linux command from the XenCenter host console.
1. Place the everRun installation CD into the CD-ROM drive of XenServer Host 1.
2. In XenCenter, type the following command at the host console # prompt to make
sure you are connected to the running XenServer Host 1:
mount -r /dev/cdrom /mnt
3. To launch the everRun Installer wizard from the host console, type the following
command at the # prompt in the Host 1 console window:
bash /mnt/everRun-5.1.1SP-installer.bin --install
4. Press Enter to start the installer.
To start the wizard using a shared directory:
1. In XenCenter, make sure your Windows management computer is connected to

your XenServer hosts.
2. Make sure the contents of the ISO file containing the everRun software are stored
in the shared directory.
3. In XenCenter, select the pool master host in the resource pane at left, then click the
Console tab.

4. In the XenCenter host console, enter the mount command at the # prompt:
mount –t cifs //<yourcomputername>/<sharedfoldername>
/mnt –o user=<yourusername>
5. When the screen prompts you, enter the password for your Windows computer.
6. To run the installer file from the master host, enter the following command at the
# prompt:
bash /mnt/everRun-5.1.1SP-installer.bin --install
Running the Installer Wizard

The Installer wizard is very similar to the installer you used to install your XenServer
software. After you begin the install process, the Marathon license agreement displays.
To run the Installer wizard:
1. Press the Tab key so the scroll bar at right changes to red, then scroll down and
read the Marathon license agreement. Press the Tab key to highlight Accept and
press Enter.
The next screen shows the Sun Java Runtime Environment license.
2. Again, scroll down and read the Sun Java Runtime Environment license
agreement. Then press the Tab key to highlight Accept and press Enter.
Next the installer asks you to select the XenServer storage repository (SR) where
it should install everRun, and requires that the storage system should have at least
3.9 GB of available disk space. The screen displays all the SRs you have configured
to have access to the XenServer host. SRs are listed in the order of priority as
recommended by Marathon — with local storage at the top of the list, followed by
shared storage.
3. Select the storage repository where you want to install the everRun software. When
you have decided on a location for the software, tab to OK and press the space bar
to enter your choice.
The rest of the installation process is automatic, and runs without user interaction.
The final screen provides the URL you will need to open the everRun Availability
Center (eAC) — the GUI client that enables you to monitor and manage virtual
machines. The URL is the IP address of the pool master host, which the Flash-
enabled browser accesses over the network.
4. Make a note of the URL for use in opening the eAC GUI.
5. Press OK to close the Installer wizard.

6. If you used a CD-ROM to install everRun, type eject cdrom at the # prompt and
press Enter to remove the CD-ROM from the CD drive.
OR
If you used a mount point to install everRun, type umount /mnt at the # prompt
to remove the mount point.
Installing everRun on Additional XenServer Host(s)

To install the software on additional XenServer hosts, return to
“Step 8: Using the everRun Installer Wizard” on page 26 and repeat the sequence on
each host in the pool. Note that the final installer screen contains the same IP address
as it did when you installed on the pool master, because you always log into the eAC via
the pool master host.
Installing Quorum Service Software

If you plan to use quorum service (QS) in a multi-host pool with switched A-link
networks, you need to install the QS software on each of the two computers that
maintains the quorum service — the so-called quorum servers.
NOTE: Quorum service — and the need for two quorum servers — is described in the
everRun Configuration Planning Guide.
The installer for the quorum service is Setup_QSVC_5.1.1SP.exe, a Windows

executable that is part of the everRun ISO image. Use the following process to install
the software on each quorum service computer.
To install the quorum service software:
1. Copy the file from the downloaded everRun ISO onto the quorum servers.
2. On each server, locate the Setup_QSVC_5.1.1SP.exe file and double-click it. The
software installs automatically on the Windows computer.
3. Later, after you open the eAC, you can configure the quorum servers as part of the
pool configuration process. If the quorum server is not on the A-link subnet, you
may need to supply a gateway address that will enable the A-link network to reach
the quorum server.
(Optional) Updating Quorum Service Communication Ports

As installed, protected VMs contact quorum service computers using UDP port 2189,
and quorum service computers contact everRun-enabled XenServer hosts using UDP
port 2188. If these port assignments conflict with your local infrastructure, you can use
the following procedure to update the receiving port.

To update the port number on a previously installed quorum service:
1. From a command window on the quorum service computer, change to the directory
where the Marathon software is installed:
CD/D C:\Program Files\Marathon
2. Run the following command:

mtcqserver -install <nnnn>
where <nnnn> is the port number on which the quorum server receive messages
from protected VMs.
For the change to take effect, you must stop the quorum service and restart it.
Step 9: Launch the eAC Management GUI

You have installed all the elements of the XenServer-everRun system. Now open the
everRun Availability Center (eAC) GUI and configure your everRun resource pool.
To open the eAC:
1. Type the URL provided at the end of the installation program — for example,
http://10.40.196.10:8080 — into any Flash-enabled browser that has access to the
NOTE: This release supports any Flash-enabled browser such as Internet Explorer 6,
7, or 8, or Firefox 3. If you are running a 64-bit operating system on your
management computer, use a Flash-enabled 32-bit browser to access everRun.
Appendix B contains more information about browser troubleshooting.
By default, the URL directs your browser to TCP port 8080 of your pool master
host. If you specified another port when you installed everRun, that port number
will be part of the URL.
When the browser connects to the specified URL, a screen opens where you can log
in to the eAC GUI for your XenServer pool.
NOTE: Because you’ll use the same URL each time you open the eAC, it’s a good idea
to bookmark the address of the master host in your browser.
2. Enter the username and password created during the XenServer installation, then
click the Login button.
Before you can start to protect applications with everRun, you need to use the eAC to
perform several pool-wide configuration tasks, which are described under Step 10.

Step 10: Configure the Resource Pool
This section describes the pool-wide configuration tasks you need to perform in the eAC
in order to prepare your resource pool for everRun.
• Install the license key.
• Configure the everRun availability link (A-link) networks.
• Configure the quorum service computers, if used.
• Check the pool’s isolation IP address. This provides access to the network device
that guarantees automatic fault handling within the pool.
Installing the License Key

everRun contains an embedded license that enables the software on a single host in a
demo evaluation; however, the demo does not provide the redundant physical hardware
needed for fault-tolerant protection. To achieve full everRun protection, you must apply
an everRun license key. An evaluation license lets you explore all everRun
functionality for 30 days. A product license allows you to run the purchased features
in a single resource pool for the life of the license.
To apply the everRun license key:
1. When the eAC workspace opens for the first time, it displays a message that lets
you choose the (single-host) default evaluation license or install a different everRun
license. Choose Install License to display the license pop-up window.
2. Locate the license key you obtained from Marathon Order Support.
3. Copy the license key from the text file, paste it into the License Key field of the
Enter everRun License dialog box, and click Install.

A message informs you that the license was accepted and applied.
4. Click OK to close the dialog box.
For more information on licensing, see the topics in eAC Online Help, Configuring an
everRun Pool > License Management
Configuring the everRun Availability-Link (A-link) Networks

It is highly recommended that you set up an initial pool-wide design for your A-link
networks. These links, which are critical to the successful operation of everRun, require
private, dedicated subnets for each protected VM (PVM). Later, if you wish, you can
override this pool-wide scheme when configuring an individual PVM.
See everRun Configuration Planning Guide, Chapter 4, Network Fundamentals, for

recommendations and best practices for configuring private LANs for A-link 1 and
A-link 2.
For information on using the GUI controls to configure A-links, see the topics in the
eAC Online Help, Configuring an everRun Pool > Pool-Wide Configuration of A-links.
Configuring Quorum Service (If Applicable)

As outlined in the everRun Configuration Planning Guide, Chapter 5, Quorum Service
Fundamentals, quorum service is mandatory when XenServer HA is not configured
and:
• The pool contains more than two hosts.
• A-link network(s) are configured with active components (switches, gateways,
routers — anything except short point-to-point cables).
• A configuration includes multiple sites (SplitSite®) or multiple computer rooms.
See everRun Configuration Planning Guide, Chapter 5, Quorum Service

Fundamentals, for recommendations and best practices for configuring a preferred and
alternate quorum server. For specific guidelines, choose the configuration option you
prefer and use the quorum service guidelines recommended for that option.
NOTE: Quorum service is not used on the direct-connected two-host configuration.
For information on using the eAC GUI controls to configure quorum service, see the
topics in Online Help: Configuring an everRun Pool > Quorum Service Management.

Verifying the Pool Isolation IP Address
You should also verify the pool isolation IP address before you begin to protect
VMs, in order to guarantee proper high availability operation. The pool isolation IP
address, which is set during everRun installation to be equivalent to the XenServer
management gateway default, is used to maintain availability during a host outage.
For information on verifying and resetting the pool isolation IP address, see the eAC
Online Help topics in Configuring an everRun Pool > Pool IP Isolation Address.
Working with the eAC GUI: An Overview

The everRun eAC GUI illustrated in this section lets you monitor and manage your
protected VMs using menus, buttons, and icons to simplify task management. To
provide a quick orientation, the illustration uses circled numbers to identify the five
main areas of the workspace; the following list briefly describes each area.
1 The task bar area contains the File and Help menus, as well as the shortcut
buttons for the Protect ( ) and Unprotect ( ) functions.
2 The Protected VM Summary area provides a quick way to view the status, by
category, of all VMs and protected PVMs on the XenServer hosts.
3 The resource pane shows all system resources in a Windows tree view. When you
select a resource in this panel, an orange bar highlights it, and the same resource
is highlighted in the Virtual Machine Status table (circle 4). At the same time, the
Detail tab at the lower right of the workspace (circle 5) displays detailed
information for that resource.
4 The Virtual Machine Status table contains key information about each of the
hosts, VMs, and protected VMs in the system. Check this table to learn if a VM is
a candidate for protection and to identify the level(s) of protection it qualifies for.
5 Information in the Detail tab is context-sensitive: its display is determined by the

resource selected in the resource tree. This space also contains a Welcome tab that
links you to a number of basic help topics, online documentation, and customer
support sites.
NOTE: In addition to this browser-based client, everRun has a command-line

management tool, the everRun (ev) CLI, which is described in the everRun
Online Help.

Learning More About everRun Management
After your pool has been configured, you can use the eAC to protect, unprotect, and
otherwise manage the candidate VMs. To become more familiar with the eAC, consult
the everRun Online Help as you learn how to use the eAC controls.
To learn about everRun system management:
1. Open the Help menu in the task bar, click Search, and type everRun Protection
Overview into the search field.
2. Click the topic entitled everRun Protection Overview.

This topic describes how to identify candidates (and non-candidates) for protection,
and how to protect and unprotect a VM. Follow the links from this topic for more
information about each task.
The everRun online Help also contains a section called Exploring the everRun
Availability Center that explains each part of the GUI interface. As you begin to
work with your protected virtual environment, use the Online Help topics when
you want to learn more about the interface, the management tasks, the interfaces
to use for specific management tasks, system troubleshooting, and CLI command
syntax.

everRun Installer
Online Help A
Viewing the Installer Online Help

Chapter 4, “Installing the everRun Software” describes how to run the installer wizard
with the default options. In most cases, it is expected that the installer defaults will be
used.
However, you may want to change some options because of your local network
constraints. This appendix contains examples describing the use of the installer help
options.
To display everRun Installer options:
To see all the options available in installer online help, along with a brief description of
each option, issue the install command with [OPTIONS] while the CD-ROM is still in
the CD drive:
# bash /mnt/everRun-5.1.1SP-installer.bin --install

[OPTIONS]
The installer displays the following information:
--install This parameter must be specified
--version Reports version information for this installer
--port=n Overrides default port numbers used for management

software. Two ports are used: n and n+1
--sr-uuid=uuid Optional UUID of the SR storage repository to use for

creation of the product installation logical volume
35
--help or -h Displays this text and additional information about
ports, and the SR and VG options
To display everRun Installer online help text:
To see online help that contains more descriptive text about each option, enter
one of the following commands while the CD-ROM is still in the CD drive:
• # bash /mnt/everRun-5.1.1SP-installer.bin --help
• # bash /mnt/everRun-5.1.1SP-installer.bin -h
• # bash /mnt/everRun-5.1.1SP-installer.bin
An Example: Assigning Communications Ports

The installer configures two TCP ports in the firewall on the XenServer host. These
ports, which eAC uses to access the everRun application, are identified as ports 8080
and 8081 by default. If those port assignments are inconsistent with your network
usage, this example describes how the installer options can be used to assign new port
numbers for eAC access.
The everRun installer online help displays the following information about the port
option:
The web-based management software requires two ports to be
enabled to accept remote connections. You may wish to override
the default port numbers with your own settings. These ports must
be configured identically across all XenServer hosts within the
management pool. The default configuration set up by the
installer is:
ports: 8080 and 8081
The ports are enabled by the firewall rules set via iptables.
To change the default communication ports:
1. When you issue the install command, include the specific port(s) to use:
bash /mnt/everRun-5.1.1SP-installer.bin – install --PORT=6900
This command sets ports 6900 and 6901 as the communication ports.

An Example: Managing Logical Volume Storage
If the installer reports an error in the installation process, you can use command-line
options to correct the problem. The text in the online help briefly explains what to do:
sr-uuid option
The product installation creates a logical volume for storing the
product executables, scripts, and logfiles. By default the installer
attempts to create the logical volume using storage from the default
local storage repository (SR). If the installation cannot create the
logical volume, you should use the SR option to specify the storage
repository to use. Please refer to the product documentation [or
Marathon Customer Support] for more information.
In this example, the installer reported an error in the installation process, which
involved the logical volume required for everRun storage. Instead of successfully
completing the installation, the installer sent the following message.
Could not mount logical volume storage for product installation.
Examine the logfile for additional details.
The location of the logfile is included in the final lines of the installer script.
logfiles saved to tmp/everRun...[directory path].
In the example, the logfile contained the following line:

Attach everRun storage status: No default SR
To locate and specify the UUID for the storage repository:
1. To see a list of local storage of type LVM in the pool (let’s say you are root@test1-
master ~), type the following at the console command line:
[root@test1-master ~] # xe sr-list type=lvm
When the list displays, you can select the local storage located on the test1-master
host.
uuid ( RO) : c4571f60-cee4-f929-f19a-e7e816a8d545
name-label ( RW): Local storage
name-description ( RW):
host ( RO): test1-master
type ( RO): lvm
content-type ( RO): user
uuid ( RO) : 88d5ddbb-a864-5cf9-e6dc-68ba4a5dd0d7

37
host ( RO): test1-slave
type ( RO): lvm
In this case, the first example shows the local storage on test1-master, so the UUID
you want is c4571f60-cee4-f929-f19a-e7e816a8d545.
2. Alternatively, to guarantee seeing local storage on test1-master, you can add the
hostname to the command:
[root@test1-master ~]# xe sr-list type=lvm host=$(hostname)
This command shows the UUID for local storage on that host.
uuid ( RO) : c4571f60-cee4-f929-f19a-e7e816a8d545
host ( RO): test1-master
type ( RO): lvm
3. Now you can specify the UUID for the local storage repository when you rerun the
everRun install command:
bash /mnt/everRun-5.1.1SP-installer.bin --install --sr=c4571f60-
cee4-f929-f19a-e7e816a8d545
NOTE: Although the option name is –-sr-uuid, it can be abbreviated to --sr.

Browser
Troubleshooting B
Resolving Problems with Internet Explorer

If you are experiencing difficulty using Internet Explorer to access the everRun
Availability Center, try one or more of the troubleshooting procedures documented in
this appendix.
Internet Explorer Security Level Settings

eAC requires Adobe Flash Player 9 or later. On startup, the eAC application detects
whether or not the correct version of the Flash Player is installed on your browser. If it
does not detect a suitable version of Flash Player, the eAC launcher offers the option to
download from the Adobe Flash Player site or from a local version stored on the
everRun server. To ensure operation with the latest runtime it is recommended that, if
you have an Internet connection, you always choose the Adobe download site.
If you are experiencing trouble installing Flash Player, verify that your Internet
Explorer security level is not set to High or to a custom level that does not permit
viewing of ActiveX controls. Before attempting to launch eAC, you or your system
administrator should verify that the following settings are in effect on your browser.
The Medium Default Level Security permits you to view Flash content. Should you
need to implement any Custom Level, ensure that both the Download Signed ActiveX
controls and Run ActiveX controls and plug-ins options are set to Prompt.
To change your security level:
1. Open Internet Explorer.
2. Choose Tools > Internet Options.
3. Select the Security tab.
4. Select Custom Level.
39
5. Locate the section ActiveX controls and plugins.
6. Set Download Signed ActiveX Controls to Prompt.
7. Set Run ActiveX Controls And Plug-ins to Prompt.
Windows Vista Installation Failure

When used with some Windows Vista platforms the Adobe Flash Player may be
installed but may not display Flash content. Update to the latest Flash Player to correct
the User Account Control settings that cause this problem.
To run the utility:
1. Locate the installed Flash folder and right-click

C:\Windows\System32\Macromed\Flash\FlashUtil9d.exe.
The letter changes with each Flash version, so may be FlashUtilb.exe or
FlashUtile.exe.
2. Select Run as Administrator.
3. Follow the steps to complete the Flash Player installation.
4. Restart your computer.
Windows Server 2003, 64-bit version

If you are running 64-bit Windows Server 2003 on your management computer,
Marathon recommends the 32-bit Firefox 3 browser.

terminology.
Xen bridge (xenbr)
In XenServer network configuration, the
bridge parameter defines a method of
connecting objects. For example, if a
physical interface (PIF) object connects a
network object (n) to a host object (h), the
network corresponding to n is bridged
onto a physical interface specified by the
fields of the PIF object. Thus, if a NIC is
named eth0, the associated bridge is
xenbr0.

enables you to manage XenServer hosts,
resource pools, and shared storage. It also
lets you deploy, manage, and monitor
VMs.

the applications programming interface
that supports both XenCenter GUI and
the xe command line interface (CLI).
XenServer hosts
As defined by Citrix, a host is a
homogeneous system — aggregated into a
single management entity — that can
contain virtual machines. For detailed
information, see the XenServer
documentation.
