These updates contain fixes for the following issues:
- A performance regression affecting writes to newly created virtual disk images (VDIs) on GFS2 and XFS storage repository (SR) types is fixed in this update. This issue affects VDIs created after the software updates released to Early Access on 9 October 2024 and to Normal on 16 October 2024. VDIs created before these updates, or after the update published on 21 October 2024, are unaffected.
- While this update resolves the performance regression, it does not automatically restore performance for impacted VMs due to the structure of the backing file created during the regression period. To restore performance:
- For non-persistent or layered VMs (managed with Citrix Virtual Apps and Desktops MCS): Perform a base image update.
- For persistent VMs (including master images): Take a snapshot to create a new backing file for future writes, which resolves the performance regression. Keep the snapshot until a future XenServer update is released to prevent the issue from reoccurring. Deleting it prematurely could result in the previous incorrect metadata structure being reapplied, reintroducing the performance issue.
- For test VMs: Recreate them to resolve the issue.
