Upgrading a Single Citrix XenServer 5.5 Host with XenServer 5.5 Update 1

January 20, 2010


In this article you will learn how to upgrade a single, non-pooled XenServer 5.5 host with Update 1 for XenServer 5.5.  Update 1 for XenServer 5.5 provides support for Windows Server 2008 R2 and Windows 7 guests.  Update 1 also provides numerous bug fixes, along with an updated version of XenCenter.

The following steps will be taken in the upgrade process:

  1. Download the XenServer 5.5 Update 1 upgrade file.
  2. Download the XenCenter update.
  3. Upgrade XenCenter.
  4. Shut down all VMs.
  5. Upgrade XenServer.
  6. Upgrade XenTools.

Note: There are two Citrix Support articles you will need to read BEFORE beginning this upgrade process:

  1. XenServer 5.5 Update 1 Upgrade Causes Virtual Machines to Lose Network Connectivity.  This applies if you have any Windows Vista or Windows Server 2008 VMs.
  2. Advanced Memory Support for XenServer 5.5 and Windows 7 on Provisioning Server 5.  This applies to Target Devices that use Windows 7.

Once you have completely reviewed the articles, from your XenCenter management computer, open your Internet browser, go to http://support.citrix.com  and click XenServer (Figure 1).

Another way to verify the update was successful is to start creating a new VM.  Scroll down the list of Templates and you will see three new entries (Figure 38):

  • Windows 7
  • Windows 7 x64
  • Windows Server 2008 R2 x64

Click Cancel.

After updating your XenServer, XenServer Tools must be upgraded in all VMs.  Start a VM and log in to the VM.  In the left pane, click the VM, from the menu bar click VM and Install XenServer Tools (Figure 39).

Click Install XenServer Tools (Figure 40).

Follow the prompts to install XenServer Tools and reboot the VM.

Note:  If you are installing XenServer tools into a VM that is running either Vista or Windows Server 2008, BEFORE you reboot the VM, follow the steps in XenServer 5.5 Update 1 Upgrade Causes Virtual Machines to Lose Network Connectivity.

With this article you have successfully upgraded XenCenter, XenServer and XenServer Tools.  You can now create VMs for Windows 7 and Windows Server 2008 R2.  Now that you can create a VM using Windows Server 2008 R2, you should register for the tech preview of XenApp for Windows Server 2008 R2.
