    @psafont Freezing/thawing doesn't actually suspend a VM, but it's just a part of the backup process, where I/O operations are quiesced to create a stable view of the on-disk data.

    @florent, I had to do the same for Xen Orchestra Community Edition. In my case, config.toml already contained the [authentication] section, so adding a separate config.tokenValidity.toml file did not work. Instead, I had to modify the existing config.toml located at /opt/xo/xo-server. In my opinion, it is best to keep defaultTokenValidity set to 30 days as a fallback in case no value is specified. You can then simply increase maxTokenValidity to the duration you prefer. [authentication] defaultTokenValidity = '30 days' # default value of 0.5 years # comment out and increase to 5 years #maxTokenValidity = ' 0.5 year' maxTokenValidity = '5 year'

    @mpiton thanks for sharing docs, the crucial part was openssl rand -hex 32 my password was too simple and that's why i got :"Query authentication does not match server setting" error after setting 32 characters password i got my metrics, in both http://localhost:9004/metrics and http://<xo-ip>/openmetrics/metrics

    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.
