    I tried this on my lab (with XO 6.9.1), moving the pool master to the other host with xe pool-designate-new-master and then back. XO stayed connected both times and picked up the new master, even though Settings > Servers still showed the old host's address; on the way back it took a minute or two to catch up. I didn't test 6.2.2, and I used the CLI rather than the XO 5 Advanced tab, so my guess that your older version is the difference is only a guess. For the XVA, I'm not aware of release notes for the appliance image itself: it updates itself after import, and the notes that exist are per XO version, in the monthly blog post and the changelog, both linked from https://docs.xen-orchestra.com/getting-started/releases#release-cadence-and-channels . How often the downloadable XVA gets rebuilt I don't know, so the 2025.12 tag may just be the date of the base image, but I'd rather ask than guess.

    I ran into the same problem with DR replicas. Ignoring VMs by tag would solve the problem, but so would excluding the ip address information.

    Hi! We recieved a fix via the support after opening a ticket as suggested. Now the pool metadata backup is running smoothly again. As far as i know 6.9 will become "stable" after 6.10 is released. I'd still suggest a patch for the stable version, unless the new release is a few days. Best wishes Jacob

    @bug-meister My opinion is that cloud-init should be used only for the most basic stuff like initial network configuration, initial user creation and credentials injection. As soon as you gain the ability to access the VM, some more robust configuration management solution like Ansible should take over. ansible-pull mechanism is in today's day and age effectively deprecated. Just run Ansible after the VM has been provisioned to apply the configuration. If you need to call Ansible as soon as VM is provisioned without any manual invocation, you can have Terraform provision the VM and call Ansible right after that. You can even use pure Ansible for both - provisioning, with my community.general.xenserver_guest module, and configuration. You just invoke Ansible once and everything will be done in one go. The only drawback is that my module does not support cloud-init so you would need some trickery to do the stuff.

    You have a problem on your XCP-ng, this is not related to a XO issue. It's stuck doing a snapshot, which is really a basic operation that shouldn't fail at all. Double check your SMlog on the host.

    It looks like I can remove the remotes and set them up again, and configure the backup jobs to address the new share. That's okay, there are not too many.

    You need one XOA, connected to both pools. It will stream the VM content (delta) from the source to the destination. You don't need any directly link between your SR in both DCs. You DCs can be isolated with just one XOA connected to both, and it will work.

    No XCP-ng/XenServer workaround, it's a "built-in"/by design limitation (it's considered as "stalled"). So your goal would be to avoid these extremely long tasks (ie: to finish before the task is destroyed)

    You'll end up with a chain, yes (so every read will need to make "hops" on each member of the chain). Longer the chain, slower the operation. But it shouldn't be too catastrophic either (for a heavily IOPS loaded VM, you'll notice the difference, but not in other less IOPS hungry scenarios)

    Sure, thanks. I'm using xoa and desktop app simultaneously. I hope that the desktop app will be available for long time.

    No, because those logs are useful in case of problem (to find a potential bug). However, they are garbage collected automatically (the oldest ones) after a while.

    All I can tell is that's not an usual issue. Never heard of problem of this kind before… So yeah, there is something weird. Could be related to NFS permissions maybe, or something between XCP-ng and your NFS host. It's not XCP-ng code directly, because otherwise everyone else using NFS will endure the same problems. So it's more a "combo" between XCP-ng and your NFS within your infrastructure. Please read the wiki on where to check logs (especially SMlog) to spot potential hints on where's the issue.

    @S-Pam Having a VIF for management and one for storage-traffic is a good solution, we do it that way to avoid crippling management during backups.

    Any ideas for a more elegant way than to write a script? For my point of view vApps should work without HA mode but unfortunately it doesn't work on my XCP-ng server. Only console/script start of the vApp using xe appliance-start uuid= "set here the uuid of the vAppp" is working. But it is again rework for the next XCP-ng version, I think manually set vices in systemd are not persistent through an update. Will vApp supported also in future? there are some discussions about it, if really needed.

    A soft reboot will try to migrate existing VMs (ie running on this host) to another host in the pool. Using Xen motion, so only if there is a shared storage. If it fails, then you need a force reboot, that will shutdown the VM, and then reboot the host.

    IIRC, we based the button in XO to do both modification at the same time when you set it up for a VM (in the pool if it's not enabled and in the VM). However, it's been a while I didn't check the code, I'll take a look to be sure
