Hotfix XS602E010 for XenServer 6.0.2

Citrix has released the 10th hotfix for its XenServer 6.0.2 platform.

Issues Resolved In This Hotfix

This hotfix resolves the following issues:

  1. Customers may experience a delay when booting a Virtual Machine (VM) from a PVS Server. This hotfix changes the way the PVS device is detected and resolves the iterative delays that may occur during the first stage of the boot process of a PVS device.
  2. Running more than two DHCP servers when attempting to boot a VM from a network, can cause the VM to incorrectly wait for a reply from the DHCP server and eventually time out.
  3. Attempting to boot VMs from a network where the boot files are hosted on a server other than the DHCP server, can cause the VM boot to fail.

Installing the Hotfix

Customers should use either XenCenter or the XenServer Command Line Interface (CLI) to install this update. As with any software update, please back up your data before applying this hotfix. Citrix recommends updating all hosts within a pool sequentially. Upgrading of hosts should be scheduled to minimize the amount of time the pool runs in a “mixed state” where some hosts have been upgraded and some have not. Running a mixed pool of updated and non-updated hosts for general operation is not supported.

Installing the update using XenCenter

  1. Download the update to a known location on a computer that has XenCenter installed.
  2. In XenCenter, on the Tools menu, select Install New Update. This displays the Install Update wizard.
  3. Click Nextto start the Wizard.
  4. Click Addto upload a new update.
  5. Browse to the location where you downloaded the hotfix, select it, and then click Open.
  6. From the list of updates select XS602E010.update and then click Next.
  7. Select the hosts you wish to apply the hotfix to, and then click Next.
  8. Follow the recommendations to resolve any upgrade prechecks.
  9. Click Install to start the installation.

NOTE: The XenCenter controlled upgrade process reboots each host sequentially starting with the Pool Master, where possible VMs will be migrated to other running hosts to avoid VM downtime. When the Pool Master is being rebooted, XenCenter will be unable to monitor the pool.

Installing the update using the off-host CLI

  1. Download the update to a known location on a computer that has the XenServer CLI or XenCenter installed.
  2. Extract the xsupdate file from the zip.
  3. If using Windows, start a Command Prompt and navigate to the XenCenter directory, for example:

    cd C:Program filesCitrixXenCenter

  4. Upload the xsupdate file to the Pool Master by entering the following commands: (Where hostnameis the Pool Master’s IP address or DNS name.)

    xe patch-upload -s <hostname> -u root -pw <password> file-name=<path_to_update_file> XS602E010.xsupdate

    XenServer assigns the update file a UUID which this command prints. Note the UUID.

    d66cb2ea-3549-49d6-9eb8-c635385f76e3

  5. Apply the hotfix to all hosts in the pool, specifying the UUID of the hotfix:

    xe patch-pool-apply uuid=<d66cb2ea-3549-49d6-9eb8-c635385f76e3>

  6. Verify that the update was applied by using the patch-listcommand.

    xe patch-list -s <hostname> -u root -pw <password> name-label=XS602E010

    If the update has been successful, the hostsfield will contain the UUIDs of the hosts this patch was successfully applied to. This should be a complete list of all hosts in the pool.

  7. To verify in XenCenter that the update has been applied correctly, select the Pool, and then click the General tab. This displays the Pool properties. In the Updates section, ensure that the update is listed as Fully applied.

NOTE: After installing the hotfix, customers must shut down the affected VMs and start them again for the hotfix to take effect.
