XCP-ng 8.3 updates announcements and testing

stormi

We just published most of the updates tested above, plus embargoed security fixes:

https://xcp-ng.org/blog/2026/04/28/april-2026-security-and-maintenance-updates-for-xcp-ng-8-3-lts/

The release of the QCOW2 image format feature (packages sm, sm-fairlock and blktap) is planned in the coming days. You can still update a system which has these test packages with the security updates published today.

Thanks everyone for the tests!

@stormi Updated 2 pools @office but on both RPU failed after updating master and emptying secondary host. Had to install patches manually and then move VM's back......

Well I just ran rolling pool update on my 2 host home lab. I wanted to watch to make sure there were no issues. Of coarse I got distracted. Only to come back and find both host updated and running. Will continue to monitor.

Updates deployed, no issues so far.

Have you kept the logs?

manilx

@stormi Did not check logs but if you tell me what to look for I can.
In config-logs on XOA there is nothing relevant.

I updated both my test and production XCP-ng environments.

No issues during updates on all 6 hosts.

@MajorP93 Pls note that the updates had no issues. Just the RPU did not complete. 2 different things.....

@manilx It's absolutely clear to me that the method of installing updates and the changes provided by the updated packages are 2 different things.
I was not commenting on your message but rather sharing my own experience with this round of patches as this thread is generally related to XCP-ng patches.

@MajorP93 As you replied to my message and not to stormi.... Just wanted to clear up any misunderstanding.
