XCP-ng 8.3 updates announcements and testing

Andrew

@rzr Update installed and running on pools. Normal operations seem good. Had some issues with rolling pool reboot, but that happens a lot (unrelated to updates). An updated bind-utils would be nice, and any other SSL affected packages.

We pushed the tested updates to the xcp-ng-updates repository, check blog post for summary and related advisories:
https://xcp-ng.org/blog/2026/06/02/june-2026-updates-1-for-xcp-ng-8-3-lts/

Thank you again for feedback we will try to address reported issues on next batch (to come soon).

Note that some issues are not related to this specific update batch, but might have been introduced on previous ones (TBC).

@Andrew We'll publish a fix for bind-utils, indeed, even if it's not part of the officially supported additional packages for XCP-ng, as it can be useful and we don't have strong reasons not to fix it.

Regarding other packages affected by the openssl update, @rzr handled many of them as part of the OpenSSL update back then already, so now we'll mostly rely on reports such as yours in case we missed something which is actually used by the user community.

Not knowing myself what it meant, I asked Philippe: it's about the nslookup issue. And potentially the issue reported by @ph7 but it's not clear to me yet if there was a problem with XCP-ng or Xen Orchestra.

Anyway, basically this means that there's no known issue caused by this batch of updates, and that we'll keep addressing any relevant issue in the next updates if necessary, as usual.

Applied patches at work. 3 pools updated with zero issues.

latest patches, host1 /master patches went well and rebooted. moved vms over.
host 2 in pool click on patch and it just sat there.

i ssh into the host2 yum clean metadata and yum update manually applied updates.
XO still showed host 2 needing patching, so i reboot it. XO still showed host 2 need patches.
I rebooted XO. host 2 shows patch, and task still remains in XO. Any idea how to clear it out from XO. or is it wait 24 hours kinds of thing?

Did you try to reboot it just after ?

XO still showed host 2 needing patching, so i reboot it

Seems not.

What about rebooting the host too ?

Let me pass the world to @Team-XO-Backend

Hi @rzr,
When you say, "XO still showed host 2 needing patching", does that mean XO is still showing missing patches?

If so, can you run the following command: xe host-call-plugin host-uuid=<uuid-host2> plugin=updater.py fn=check_update

marcoi

after i manually applied the patches, i used XO to reboot the host 2.
After the host 2 rebooted, XO still showed the task running and the host2 showed it needed to be patched. I rebooted XO and the task is still there ( been there for 13 hours now lol. ) but now host 2 shows patched

@marcoi perhaps a restart toolstack would correct the phantom task ?
but at the end of patching of the master a restart toolstack should have happened already, automatically...
