Hotfix XS65ESP1027 - For XenServer 6.5.0 Service Pack 1

Who Should Install This Hotfix?

This is a hotfix for customers running XenServer 6.5.0 Service Pack 1.

Issue Resolved In This Hotfix

This hotfix resolves the following issue:

• Virtual GPU (vGPU) assigned VMs may fail to restart completely without intervention. This happens when the vGPU emulator process gets blocked, preventing it from servicing the VM's vCPUs, and eventually cause the VM to become unresponsive during restart.

Note:??Customers using NVidia virtual GPU technology should download the latest NVIDIA vGPU drivers for XenServer 6.5. See??NVIDIA Download Drivers??page to obtain the latest drivers.

Installing the Hotfix

Customers should use either XenCenter or the XenServer Command Line Interface (CLI) to install this update. As with any software update, 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 are upgraded and some are not. Running a mixed pool of updated and non-updated hosts for general operation is not supported.

Note:??The attachment to this article is a zip file. It contains both the hotfix update package and the source code for any modified open source components. The source code is not necessary for hotfix installation: it is provided to fulfill licensing obligations.

Installing the update by 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 Update. This displays the Install Update wizard.
3. Click??Next??to start the wizard.
4. Click??Add??to 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??XS65ESP1027.xsupdate??and then click??Next.
7. Select the hosts you wish to apply the Service Pack to, and then click??Next.
8. The??Install Update??wizard performs checks to ensure there is sufficient space to upload the update. If there is enough space, the wizard successfully completes the upload. If there is insufficient space to upload the update, an error will be displayed:
   • To free up required space, if there are any residual hotfix update files remaining on the host that can be deleted, the wizard offers to clean up these files. Click??Clean up??to review your options and remove the files. Note that this action does not uninstall hotfixes.
   • If the??Install Update??wizard cannot free up the space required for the upload, you must manually delete files on your host. Click??More Info??for information about space required and take necessary action to free up the required space.


9. The Install Update wizard performs a number of update prechecks, including the space available on the hosts, to verify that the update can be applied on the selected servers and displays the result. Follow the on-screen recommendations to resolve any update prechecks that have failed. If you want XenCenter to automatically resolve all failed prechecks, click??Resolve All??and click??Next.
10. Choose the??Update Mode. Review the information displayed on the screen and select an appropriate mode and then click??Install update.

Note:??If you click Cancel at this stage, the??Install Update??wizard reverts the changes and removes the update file from the host.

11. Click??Install update??to proceed with the installation. The Install Update wizard shows the progress of the update, displaying the major operations that XenCenter performs while updating each host in the pool
12. When the update has been applied, click??Finish??to close the wizard.
13. If you chose to carry out the post-update tasks, do so now.

Installing the update by using the xe Command Line Interface

1. Download the update file to a known location.
2. Extract the xsupdate file from the zip.
3. Upload the xsupdate file to the Pool Master by entering the following commands:??
   (Where??hostname??is the Pool Master's IP address or DNS name.)
   

   xe patch-upload -s??<hostname>??-u root -pw??<password>??file-name=<path_to_update_file>\XS65ESP1027.xsupdate

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

   a2de7b16-4773-4aa5-be49-ea2888ff3edb



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

   xe -s??<hostname>??-u root -pw??<password>??patch-pool-apply uuid=a2de7b16-4773-4aa5-be49-ea2888ff3edb

5. Verify that the update was applied by using the??patch-list??command.

   xe patch-list -s??<hostname>??-u root -pw??<password>??name-label=XS65ESP1027

   If the update is successful, the??hosts??field contains the UUIDs of the hosts to which this patch was successfully applied. This should be a complete list of all hosts in the pool.
6. To verify in XenCenter that the update is 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.
