    @olivierlambert Oh okay, thanks for responding. So I turned off SYNC and COMPRESSION on the dataset and retested (by suspending 11 VMs), I immediately noticed a whopping performance improvement (essentially sustained wire speeds AND 50% faster completion time*) : Roughly 984 Mb/s sustained WRITE speeds (during VM suspension) Roughly 984 Mb/s sustained READ speeds (during VM resumption) Transfer time for both READ and WRITE is about 20 minutes (down from 40-45 mins) [image: 1753218219233-screenshot-2025-07-22-170106.png] Gonna retest with SYNC disabled and COMPRESSION re-enabled and see if it degrades performance; standby for another report.

    @DustinB said in Backups started to fail again (overall status: failure, but both snapshot and transfer returns success): @peo said in Backups started to fail again (overall status: failure, but both snapshot and transfer returns success): @olivierlambert Thanks, will update every machine and XO involved in the backup process, and possibly even the individual machines that fails. First failure on vm-cleanup was 15 July, that's a few days before I patched the hosts (as a part of troubleshooting and preventing further failures). Still these backups will (probably) be fully restorable (as I have tested out with the always-failing Docker vm) So you patch your host, but not the administrative tools for the hosts? Seems a little cart before the horse there, no? That's a fault-finding procedure: do not patch everything at once (but now I did, after finding out that patching the hosts did not solve the problem)

    @StephenAOINS This endpoint is not currently present in our REST API swagger, but we do plan to add it to the list of endpoints. We are currently finalizing the migration of existing endpoints, the next step will be adding new ones. We will keep you informed when it is available. Feel free to come back to us if you want to learn more and follow our blog posts. have a good day

    Hey there! It's a good thing to start by reading our doc. If you enter "Password" in the search field, you would have find: https://xen-orchestra.com/docs/troubleshooting.html#recover-web-login-password As you are using Xen Orchestra into production, may I suggest to go for XOA with pro support at some point?

    @olivierlambert Maybe. Ive created a support ticket for now. Hopefully you can see if the problem is a configuration mistake on our end or a problem in XO. Thanks.

    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]

    @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.

    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.
