This behavior has been improved for sequential reads, but not for other types of read. When read caching is enabled it is slower to read from the parent snapshot than from the leaf. If you wait until after the console refreshes twice, the console then accepts keyboard input. When attempting to use the serial console to connect to a Citrix Hypervisor server, the serial console might refuse to accept keyboard input. On some hardware, you cannot run the same number of VMs with Citrix Hypervisor 8.2 as you can on the same hardware with XenServer 7.6 and earlier. The increase in the amount memory allocated to dom0 in Citrix Hypervisor 8.0 can mean there is slightly less memory available for running VMs. Rebooting the VM, for example, by clicking ‘Reboot’ in XenCenter, does not update the VM's feature set.
To update the VM to use the pool’s new feature set, you must power off and then start the VM. (For example, when a new host is added to an existing pool, or when the VM is migrated to a host in another pool.) When a pool’s CPU feature set changes, the VM continues to use the feature set which was applied when it was started. (CP-32460)Ī pool’s CPU feature set can change while a VM is running.
If your Citrix Hypervisor servers run on hardware containing Intel Sandy Bridge family CPUs, shut down and restart your VMs as part of updating or upgrading to Citrix Hypervisor 8.2 from Citrix Hypervisor 8.0 or earlier. This article contains advisories and minor issues in the Citrix Hypervisor 8.2 release and any workarounds that you can apply.
