    @florent I rebuilt my XCP hosting environment (everything is faster and bigger stuffed into one rack).... and this issue is now worse. The main changes to this new setup are 2x40Gb networking, faster NFS NVMe NAS, faster pool servers, more memory, much faster CR destination machine with ZFS. Running XCP 8.3 (March 2026 updates) and XO (master a2e33). Replication is leaving many attached to control domain every day with NBD connection set to 2. Changing it to 1 seems to resolve the issue (no more stuck to control domain).

    Version 1.4.0 is released: https://codeberg.org/NiXOA/system/releases/tag/v1.4.0 It includes significant changes and improvements, including: dedicated getting started section, migration to valkey, only needing to clone system, and helper scripts. the xen-orchestra-ce nixpkg now references the libvhdi nixpkg, and the core flake now references and pulls from the xen-orchestra-ce repo as an overlay. System (the user input flake) now uses the Core repo as an overlay, reducing the need to clone both locally AND allowing system to pull new updates and releases from core. XO, and libvhdi as needed. The next goal is: Make an xsconsole-like TUI Automate package updates for libvhdi and xen-orchestra-ce using CI/CD pipelines Submit libvhdi and xen-orchestra-ce as official nixpkgs

    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. iw0der created this issue in xcp-ng/xcp closed This operation cannot be performed because the specified virtual disk could not be found #282

    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

    For the moment I've had to create several backup jobs instead of one big backup it's e.g. servers01-06, 07-12, 13-18. Which isn't ideal as it's harder to manage, but is what it is!

    Hard to say from just a screenshot. What version of XO are you running? How long did you wait for the logs to load? Did you try refreshing the page? FWIW, I've noticed that XO seems to take longer to load this page than it did previously. P.S. Technically, you aren't running XOA (the pre-built XO appliance).

    XO on Raspberry Pi 3B+ ?

    I've been spending some time on it for the last few nights, and my skills are improving little by little. I think Ubuntu desktop was the closest I got to functional, there is a custom image for the Rpi3b+ that I found and it was one of the attempts that got to trying to start the XO-server service and failed. I was never able to get the xo-server to start manually either and the log files didn't give me anything I understood. One of the versions that worked the least was CentOS 7 for RPi, node.js is not available for it in the normal repos. I have more experience with CentOS from a few years ago and more comfortable with it, may have to look into compiling all the dependencies from source to see if I can make it work. I think an RPi 4b with 2gb or 4gb of RAM might be a better choice, but I have the 3b+.

    This guide shows an old UI of XO, but you can always set the HA for the VM in its Advanced Tab. HA at the pool level might be enabled using the command displayed in the blog post. So far enabling HA on the pool level isn't exposed in XO because HA is causing more issues than it solves in general. If you decide to enable it on the CLI, it means that you probably understand what you do. If you don't know where to find a SR UUID, using HA might expose you to VERY bad experience. BTW, you can find it in SR view, click on the SR you want to use as HA SR, you'll see the UUID just beneath the name. As someone said in this forum few weeks ago: Everybody wants HA but not everyone needs it
