    @rzr I thought i pressed save after editing the backup job to enable the purge snapshot when using cbt. After re-enabling and clicking save. All is good now. No errors no stuck coalescence after backups.

    Hi! Very likely missing Xen drivers in the image. See https://docs.xcp-ng.org/installation/migrate-to-xcp-ng/#-from-kvm-libvirt that could be helpful. Keep us posted and welcome! edit: it's one way to do it, but booting on a live CD (eg Ubuntu) and mount the VM disk to do the dracut command with chroot first will also work if you don't have a buffer machine to do the dracut then export. If you need more details, happy to guide you.

    @delacosta456 do not take into account the pool CPU USAGE... for example I have a pool with one host, here is the POOL CPU USAGE : [image: 1777025885316-e10b4be9-7b53-452d-a97a-42e249031e66-image.jpeg] yeah right ... 600% the host : [image: 1777025918278-38ee47ed-c9e6-4cc9-8f45-ec875211d86e-image.jpeg] BUT, if you switch on the STACKED VALUES [image: 1777025953774-4f6a3e1f-9de1-4642-bcdf-d04891d0b70f-image.jpeg] you get the POOL CPU USAGE value... it adds up all core usage, so... not a very good view...

    Hello, I’m experiencing an issue on an XCP-ng cluster using XOSTOR. Environment: 3-node XCP-ng cluster XOSTOR distributed storage (2x2Tob nvme on each host) XOA for management Management network 1Gb/s Storage Network 10Gb/s MTU 1500 everywhere (no jumbo frames) So during VM migrations, creation, destroy XOA loses connection to my host pool, VMs keep running normally Hosts remain reachable (SSH / HTTPS / ping OK), Connection comes back after some time 30s to 1min. Observations: No significant CPU or RAM saturation No obvious disk latency issues (iostat looks normal) No errors reported on NICs xapi process remains active (no crash or freeze) The problem is intermittent and seems random. i've monitored nic with iftop and i see no bandwith bottleneck et and can see that XOSTOR is using 10gb network only. Has anyone experienced similar behavior with XOSTOR? And how to Fix it ? Thanks in advance for your help.
