i switched one of the backups for my extra pool from nfs to smb and its been sitting so i expect it to fail. might be a smb issue. ill update this post with results once it either fails or works

i did test smb and it works.

back to nfs works

@JB both
Also Xen Orchestra, commit be960

@JB seems okay after a few back to back runs.

looks like mine also just started working.

looks like im getting the xo config backup body timeout error as well.
Xen Orchestra, commit a94eb
Master, commit 9c6d1

went well with test systems. going to do prod soon.

i think im seeing the same with fake cpu spikes. I started a second pool yesterday to patch and left it on over night. typically i just shut it down once done so the servers dont get too far behind patching.
Under the pool stats im seeing spikes but under hosts nothing.
It doesnt really bother me, but figure i add to the thread that im also seeing it.

same with me and latest update

Same for me.

ill try to update manually and see if it changes.

Applied the latest pushed updated to production, no major issues.
The only thing to note is my backup XCP config failed Sunday, some time post the patches being applied. The error was the Body Timeout Error. This morning the backup ran without issues. Not sure why, but it wasn't a big deal and it working now. So not sure tied in with patching or not.

dmidecode -s system-product-name

that fixed it

i see the sensor info when i run ipmitool sensor on the server. So i took that info and put it into pluggin reg settings.

pluggin

my host shows OEM generic info as manufactor

So am I doing something wrong to get the general stuff working on asrock motherboard?

update to latest test patches on 2nd pool. no issue. LACP worked, started UB26 VM on host 4 and live migrated to host 3.

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

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?

We pushed the updates to the xcp-ng-updates repository: https://xcp-ng.org/blog/2026/05/21/may-2026-updates-3-for-xcp-ng-8-3-lts/

Changed since the initial announcement, xen was updated with the proper vulnerability fix and an update to sm was added to fix an issue on LVM-based SRs with CBT enabled.

Thanks everyone for your feedback!

update main pool. so far so good. updates went well and vms are running.

New security update candidates for XCP-ng 8.3 LTS (kernel, xen, intel-microcode)

i tested on one of my extra pools and so far i didnt see any issues. Grated i dont do much on that pool but i created a ubuntu 26 VM without issues.

Ill wait for full release to do my main pool.

@olivierlambert lol okay got it

@stormi I getting a response to reboot after applying to master.

anyone know if applying these two patches requires rebooting?
