    Hi all, I have a fresh green fields install of Xen Orchestra with 3 x 8.3.0 servers. The servers have 8 interfaces, of which I installed the management IP and VLAN on eth0, then connected all 3 to XO and added into a pool. I then created a bond for eth0 and eth1 per https://xcp-ng.org/blog/2022/09/13/network-bonds-in-xcp-ng/ and the master failed to take any network config, and the 2 slaves both lost connectivity, even after a reboot. Am I doing this correctly or did I miss something?

    @Cyrille said in How to deploy the new k8s on latest XOA 5.106?: @ferrao open the VMs list (Home>VMs), click on "Filters" near the search bar, and then click "Save...", in the popup dialog enter a name for the filter and click "OK". [image: 1746456413368-snapshot_2025-05-05_16-41-58.png] This should be enough to workaround the 2nd bug that happened at the end (that prevent to save the tag that is added to the clusters VMs) Hello. Thanks, it seems to have worked. The deployment screen no longer hangs. However I don't get any feedback at the finish. And on the Task log, the log about the Kubernetes cluster seems to be gone: Cannot GET /rest/v0/tasks/0mabaot5t I've selected this task: API call: xoa.recipe.createKubernetesCluster 2025-05-05 13:28 Is this expected?

    Thanks for your feedback, we'll discuss internally if there's any other possible approach (and I'm not sure).

    Hello, I suggest you look also for Packer to build ready to use VM templates, with cloud-init, guest tools, and the softwares you'd need. There's a blog post for this https://xcp-ng.org/blog/2024/02/22/using-packer-with-xcp-ng/.

    @olivierlambert said in un-zstd .xva files exported with XOA?: Hi! Again, before starting to talk about technical solution, can you explain the use case? If you have zstd installed on your machine, yes. It's a tar with compression (gzip or zstd). But then it won't be trivial to assemble VM data (but you can exctract metadata easily!) I didn't really mean disassemble the .xva, but rather create an uncompressed .xva that has broader support/portability. The zstd command line tool seems to be able to uncompress it just fine. Thanks.

    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.

    @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.
