@RobWhalley I think in the beginning i had that option enabled in my backup jobs, but found it was a hassle to move VMs between hosts with it on so i turned it off for all backups. Might be why my jobs worked because i had already done that switch in the past.

posted in the other thread as well but Xen Orchestra, commit 1a7b5 backups are working again. I tested configure and vm backups. They are being backup to NFS share.

marcoi

updated my two hosts without issues.

marcoi

updated on my three servers no issues.

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.

marcoi

Same for me.

ill try to update manually and see if it changes.

try downgrading your nfs to use version 3. I think version 4.x has performance issues.
in you settings-->remote, you can edit the nfs mount for backups and add in the -o options section.

I dont know the exact command but you can try using nfsvers=3 and see if that helps.

marcoi

scratch that prior comment. My backups are all setup as delta backup with schedule 2nd run that forces full backup. So i believe both are working correctly.

if you can also try deleting all the backup snapshots of the VMs in the backup and running full backup then the delta backup jobs.

Updated to commit -db8ad this morning and backup is working.

marcoi

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

marcoi

@JB both
Also Xen Orchestra, commit be960

marcoi

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

marcoi

looks like mine also just started working.

marcoi

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.

marcoi

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.

marcoi

same with me and latest update

marcoi

Same for me.

ill try to update manually and see if it changes.

marcoi

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.
