    @acebmxer Yes, 22 or 24 should work correctly. Some early versions of 24 had issues, but not currently. I'm running 24 and it is working.

    @florent I updated XO to master 60ba5, and still having the issue. I don't see any errors in the backup log. It just says "isFull": true for the ones stuck on full backups. The XO log just reports: Mar 24 16:26:47 xo1 xo-server[21199]: 2026-03-24T20:26:47.315Z xo:backups:worker INFO starting backup Mar 24 16:26:52 xo1 xo-server[21199]: 2026-03-24T20:26:52.359Z xo:xapi:xapi-disks INFO export through vhd Mar 24 16:26:54 xo1 xo-server[21199]: 2026-03-24T20:26:54.410Z xo:xapi:xapi-disks INFO export through vhd Mar 24 16:29:22 xo1 xo-server[21199]: 2026-03-24T20:29:22.250Z xo:backups:worker INFO backup has ended Note, it reports two export through vhd and does two full backups and one delta.

    Version 1.4.0 is released: https://codeberg.org/NiXOA/system/releases/tag/v1.4.0 It includes significant changes and improvements, including: dedicated getting started section, migration to valkey, only needing to clone system, and helper scripts. the xen-orchestra-ce nixpkg now references the libvhdi nixpkg, and the core flake now references and pulls from the xen-orchestra-ce repo as an overlay. System (the user input flake) now uses the Core repo as an overlay, reducing the need to clone both locally AND allowing system to pull new updates and releases from core. XO, and libvhdi as needed. The next goal is: Make an xsconsole-like TUI Automate package updates for libvhdi and xen-orchestra-ce using CI/CD pipelines Submit libvhdi and xen-orchestra-ce as official nixpkgs

    You can't, indeed, live migrate a VM from Intel to AMD (or vice-versa), for obvious reason (the VM will try to call Intel specific instructions after migrating on an AMD CPU, the result would be… a crash!) We had a similar migration ourselves (in our own prod), from Intel to AMD. And we decided to use Continuous Replication to make a first "backup" on destination (the full) while the original VMs were running (no service interruption). Then, we shut down the VMs, make another round of replication (delta, very fast) and then we booted on destination.

    @olivierlambert That socket issue was not what was causing the problem, I went through setting by setting and if I choose 2GB of memory for a VM I get constant reboots when using XOA. I was able to repeat the issue with a number of OSs not just RHEL 8 (and variants). I havent went through and compared the differences between XOA and XenCenter yet.

    @s-pam said in Multiple remotes in a backup - how is retention calculated: OK Great. So if I set retention to 10, it would keep 10 copies on each remote? Yes. it will keep 10 copies on each remote.

    In theory, Xen Orchestra got a protection against this issue (see https://xen-orchestra.com/docs/backup_troubleshooting.html#vdi-chain-protection ) So you have to find what's causing a long chain outside XO. You can check in XO, in the Advanced tab of the SR view, if there's VDI to coalesce. Or maybe very long chain for other reasons, there's a tool we made called xapi-explore-sr.

    Use CR instead of DR then, it will send only the diff to the other host, so it will be faster.

    I can migrate this VM from another host (7.6) to the 8.2 host just fine: [image: 1612363337871-29412a19-7047-4feb-a82e-1b3d3ce61a94-image.png] Im not sure what the agent actually is, thats why im guessing this might be related [image: 1612363441628-eb67e1dd-0979-4b17-94a8-b3d4f72397a5-image.png] VM that fails: [image: 1612363482511-153e71d2-3779-4894-b990-3b4f6b02e032-image.png]

    @nodesocket Depends on your setup. For mine, I use sudo systemctl restart xo-server.service. You could also just restart the VM.

    @s-pam said in ova problems: @crazytoo Best way to be sure it to boot the VM using a live-cd, for example systemrescue-cd or ubuntu live-dvd. Then you can use tools like gparted to inspect your disk image from inside the booted vm. That's exactly what I advised to do earlier, but it seems it was missed the first time I think that's the best approach to understand what's going on in the VM disk.

    @jedimarcus No. But I think the problem could be an issue where I merged two remote backup trees.

    Complete solution is delete delete all jobs with type "call" then delete this job ids from job_ids table. After this delete all schedule's with this job ids. And then delete this schedule ids from schedule_ids table.

    Hi, I think the issue was already reported on EVE-ng forums. It's a problem with their image and Xen, if I remember correctly.

    Hi, We never had the time to formalize that. But we do something "close": feature requests via paid support ticket are given a top priority. For the community feedback, it's pretty easy to see what's the most required via github repo or here.
