Paravirtualized (PV) mode VMs are not supported on Citrix Hypervisor 8.2. This hotfix includes a change that prevents unsupported 32-bit PV VMs from starting. Before applying this hotfix, ensure that the following is true:
Earlier versions of XenCenter rely on a paravirtualized transfer VM to facilitate OVF/OVA import/export and single disk image import. This PV transfer VM is no longer supported.
Earlier versions of the Citrix License Server virtual appliance are paravirtualized and are not supported.
For the latest versions, see the Citrix Hypervisor downloads page.
For more information, see Guest operating system support
This security hotfix addresses the vulnerabilities as described in the Security Bulletin above.
This hotfix also includes the following previously released hotfixes:
Customers should use either XenCenter or the Citrix Hypervisor Command Line Interface (CLI) to apply this hotfix. As with any software update, back up your data before applying this update. Citrix recommends updating all servers within a pool sequentially. Upgrading of servers should be scheduled to minimize the amount of time the pool runs in a "mixed state" where some servers are upgraded and some are not. Running a mixed pool of updated and non-updated servers for general operation is not supported.
There are three mechanisms to install a hotfix:
The Automated Updates feature is available for Citrix Hypervisor Premium Edition customers, or to those who have access to XenServer through their Citrix Virtual Apps and Desktops entitlement. For information about installing a hotfix using the Automated Updates feature, see the Applying Automated Updates in the Citrix Hypervisor documentation.
For information about installing a hotfix using the Download update from Citrix option, see Applying an Update to a Pool in the Citrix Hypervisor documentation.
The following section contains instructions on option (3) installing a hotfix that you have downloaded to disk:
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. When the prechecks have been resolved, click Next.
Note: If you click Cancel at this stage, the Install Update wizard reverts the changes and removes the update file from the server.
xe -sCitrix Hypervisor assigns the update file a UUID which this command prints. Note the UUID.<server>
-u<username>
-pw<password>
update-upload file-name=<filename>
\XS82E035.iso
92a29dab-5df5-4ade-b2a8-25d5d75bd715
xe update-pool-apply uuid=92a29dab-5df5-4ade-b2a8-25d5d75bd715
Alternatively, if you need to update and restart servers in a rolling manner, you can apply the update file to an individual server by running the following:
xe update-apply host=<server>
uuid=92a29dab-5df5-4ade-b2a8-25d5d75bd715
xe update-list -sIf the update is successful, the hosts field contains the UUIDs of the servers to which this update was successfully applied. This should be a complete list of all servers in the pool.<server>
-u root -pw<password>
name-label=XS82E035
xe update-pool-clean uuid=92a29dab-5df5-4ade-b2a8-25d5d75bd715
