@bvitnik Thanks for giving more details. I will give a try with each of them (netplan, ..etc)

@anthoineb or someone from the @team-storage, you might want to take a look (IDK if it's a known problem internally)

Hi @Kptainflintt, I don't think this is related to XO6, but probably to this PR: https://github.com/vatesfr/xen-orchestra/pull/9231 VDIs with snapshot_of: <something> are now recognized as snapshots spacotte-vates opened this pull request in vatesfr/xen-orchestra closed fix(xo-server): improve handling of xapi snapshots #9231

@olivierlambert thank for that. Just to be clear the vm was not runing but shut down if that makes a difference. @ph7 Both firewalls are Unifi Enterprise fortress gateways. - https://techspecs.ui.com/unifi/cloud-gateways/efg?subcategory=all-cloud-gateways Both sites are setup with Site Magic VPN. So should be full 1.1gbps if accurate. [image: 1767705099263-screenshot-2026-01-06-081123.png]

@Pilow Thanks, it's promising but we'll wait for more runs on your side If it's that, at least it's not a biggie in the end!

Question for @stormi

@TeddyAstie Sure thing: xl_dmesg.txt Dom0_dmesg.txt DomU_dmesg.txt

@DaleDibbadel Are you running XOA or XO from the sources? Are you up-to-date?

@wilsonqanda qcow2 packages are in a separate repository. You should have setup the repo, a grep -r "qcow2" /etc/yum.repos.d/ should tell you if it was setup on your host.

@acebmxer It's not pretty, but its failsafe. The proceedure looked like this in our case: Disable HA in the "old pool" Put a host in the "old pool" into maintenance mode Reinstall that host and connect it to XOA and then patch it Create a "new pool" from that host Create a new LUN or NFS share in the SAN for "new pool" and attach it to "new pool" Live migrate VM's over from "old pool" to "new pool" Once you've freed up another host you repeate step 2 and 3 and then join that host to "new pool". It is important that you patch it before joining it to the pool, that is done by going to Settings -> Servers in XOA and connect to it manually. And then just continue untill you're done. Live migration is pretty reliable now days, so this works pretty good and since we had 10G network its not taking as long as it used to do with 1G network. We did this after a major incident on our primary production site where 2 out of 4 hosts in a pool "suddenly" lost their NIC's after updating them. Since then we never updated the pools again. Standalone hosts are fine tho, they never did this. Luckily we had 2 other pools where we could migrate the VM's to, but we couldn't realy trust the updating after that.
