    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

    Hello there, I posted in another thread an experimental Docker containers integration, not for production, but good enough to test it, see https://xcp-ng.org/forum/topic/12423/bringing-container-visibility-back-to-xo/9?_=1791618850567

    OK the tasks (it been 8 hours since I've checked) are gone, but the VHDs localted on backup server's localstorage remains. QUESTION: How to delete VHDs that are not realted to any vm? I think it will not be deleted automatically. EG. For example - I've deleted "Atlas" VM, but big atlas VHD remains on BackupHost's local storage: [image: 666ed028-c8e0-4ae7-86f3-1a307f7eee76-image.png]

    Hi, It's possible to do it using the UI, simply create a schedule with 7 as Backup retention and 2 as Replication retention. [image: fd938a54-8730-4bcf-85c3-7caf2018ac52-image.png]

    Because there's a ton of dependencies, and we try to decouple things, this work takes time. We should be able to run on a more recent version of Node soon, and when it will be the case, our doc will be updated accordingly. That's exactly why we can't support 3rd party installers. Our doc might change and during the interval, if the 3rd party installer isn't following, then it will break.

    OK, seems I wasn't trying hard enough. I was trying to mount the tools under the iso list, but when I look further down the list to xc-ng Tools it turns out I can mount the tools from there as long as I do it manually (mount /dev/sr0 /media/blahblah). Installed now, all good.

    There's no tool to "merge" old forum or fetch old message. So for few months we'll still have old XO forum then it will be automatically redirected to the XO category here.

    It's just a missing info in a config file of the appliance. Not a big deal, just surprising to see that now, despite the fact it was there before.

    XO Delta Backup Fails to Local Storage Mounted via NFS

    Hi, So I tried using the NFS target remotes but the speed of transfer was very poor even though the connection from XO to the NFS server is over 10Gbe. XO is on the same XCP-ng host as the VMs being backed up. This XCP-ng server is connected to the NFS mount over 10Gbe network: [image: 56cc5a0a-e633-443b-9a50-6575ef5cddaf-image.png] Here is the NFS Remotes setting in XO to the backup server (FreeNAS) at IP 10.10.2.3:[image: 046fcdaa-8788-4d69-aa00-c1620a0afb46-image.png] The backup logs show extremely low transfer speed: [image: b51d304d-2fb6-472f-8eb9-0dbec967d49c-image.png]

    @olivierlambert Thanks again for the reply. I’m looking into it more. I think I need to add the storage directly to the VM running XO. I was trying to use a drive connected to a drive on my local network. Though it says it can talk to the drive, it does not reach it. I’m trying now to add an NFS to the XO server.

    You can avoid transferring some disk data with the [NOBAK] title in the VM disk. However, a VM snapshot isn't capable of ignoring a disk. This would require a change either in the way we do backup in XO (not using VM.snapshot, but VDI.snapshot instead) or modify XCP-ng API to support VM.snapshot with excluded disk. The first option will make quiesce snapshots impossible. The other one is a bit more complicated to realize, but not impossible. The issue already exists in our bug tracker: https://github.com/vatesfr/xen-orchestra/issues/2560

    This may be related to https://github.com/xcp-ng/xcp/issues/282 My guess is that the tools ISO was mounted into the XO VM, then updates were applied to the host that contained an update of the tools ISO, which led to the XO VM having an non-existing tools ISO still mounted. I have made a change in 8.1 to avoid that (eject all tools ISOs after updating the ISO, not just from shutdown VMs), and testing will tell us whether that's a good solution. To solve the situation, you usually just need to eject the ISO with xe vm-cd-eject, not xe vm-cd-remove, as @tuxen said. If you had a snapshot of the VM before removing the CD drive, I think restoring it should bring the CD drive back and then you can eject the CD with xe vm-cd-eject... Unless restoring the snapshot also fails. Else as tuxen said you need to recreate a CD/DVD device and attach it to the VM.

    It's pretty simple: just replace "xva" in the image by VHD and that's it. Otherwise it's explained https://xen-orchestra.com/docs/delta_backups.html If you still have questions, let me know
