XCP-ng 8.3 LTS Updated installer ISO
The installer ISO has been refreshed with up date packages already published.
The image can be downloaded from:
https://repo.vates.tech/tmp/xcp-ng-8.3.0-20260709.testing.iso
The procedure to install XCP-ng 8.3 remains the same.
The refreshed installer ships updated Xen, Linux kernel and some drivers/firmware, which help with deploying XCP-ng 8.3 on hardware that needs changes introduced by updates not present in previous ISO image releases.
This refreshed ISO has been validated on a subset of supported hardware. Additional testing on any hardware from the community would be greatly appreciated.
As with previous installer releases, it can be used to upgrade XCP-ng from a previous major release (8.0, 8.1 or 8.2). Refer to the Upgrade documentation. For existing XCP-ng 8.3 installations, there’s no need to use this ISO image. Regular yum updates achieve the same results as a fresh installation with that ISO image.
Installer improvements include minor enhancements related to software RAID1 support for the system disks, including support for more than 2 disks in the RAID1 array if anyone really wants that.
New maintenance update candidates for XCP-ng 8.3 LTS
This release batch includes a VBD leak regression fix in XAPI and minor changes needed to build the installer ISO.
A regression was introduced to the VM.revert operation in xapi-26.1.4-3.3, which left VBDs attached to the VM when they are not present in the reverted-to snapshot (instead of destroying such VBDs, as was done before).
VMs that were reverted to their snapshots after xapi-26.1.4-3.3 may have such "leftover" VBDs. Advanced users can use the leaked_vbds script to detect possible cases in your pools. Sadly, there is no way to automatically distinguish a VBD that was created after a VM.revert from a VBD that survived the VM.revert, so this script relies on the user to determine if the suspicious VBDs are indeed affected or not.
What changed
Control Plane
xapi: Fix non-snapshotted VBDs staying attached after VM.revert
Versions
xapi: 26.1.11-1.2.xcpng8.3 -> 26.1.11-1.3.xcpng8.3
xcp-ng-release: 8.3.0-37 -> 8.3.0-38
Test on XCP-ng 8.3
yum clean metadata --enablerepo=xcp-ng-testing,xcp-ng-candidates
yum update --enablerepo=xcp-ng-testing,xcp-ng-candidates
reboot
The usual update rules apply: pool coordinator first, etc.
What to test
As usual, normal use and anything else you want to test.
Test window before official release of the updates
~5 days
