    @dinhngtu Yeah, I suspected that as well. So I inspected the SR and it showed connected to both hosts (at least in the XO UI - I didn't drop to the CLI to really confirm). By altering my workflow a bit and slowing down, I seem to have found the right "sweet spot" of delay and the issue hasn't resurfaced. Here's what I'm doing now, when I need to revert the snapshots of all three VMs: In the XO VM list, I select the three VMs and power them off at the same time. I then start with VM1 and eject the ISO, VM2 and eject the ISO, then VM3 and eject the ISO. By the time I circle back to VM1 for the next step, about 10-15 secs have elapsed. I then start with VM1 and revert the snapshot, and repeat the same on VM2 and VM3. By the time I circle back to VM1 for the next step, another 10-15 secs have elapsed. I re-attach the ISO to all three VMs in sequence. Another 10-15 secs elapse. I then start with VM1 and power all three VMs sequentially. The entire workflow takes about 30-45 secs, and I'm finding that by doing this, the issue hasn't resurfaced.

    @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

    @hitechhillbilly Hi, For now the import tool does not use the proxy. Not that the full import tool also work from source if you need additional XOA , but we won't be able to connect to them for support

    @Danp the issue is "resolved" only because we got the host back online so it released the lock. Yes I did try Start on which is method that produced the "The VDI is not available" error no the offline host was not the pool master Yes the VDI's are on shared iSCSI storage (truenas) And I want to note that OTHER VM's that were not on that failed host were able to restart and on any other node without an issue. I was even able to delete old snapshots without an issue so clearly the storage was online and available. It is deeply concerning that we were unable to get the VMs running again and only coincidental that were were able to re-seat the ram module and get it back online -- once it rejoined the pool the locked VM started without any issues on another host, so something was clearly locking it down even though it was fully stopped and visible.

    @olivierlambert said in Migrating logs and history between XOA instances?: Hi, VM stats aren't store on XOA but on your pools, and they should be there with the same history as the old one Can you tell exactly what kind of logs are you talking about? Thanks. I had looked on the wrong VM. The stats are indeed retained. Originally I was thinking of audit logs, but I realized they can be exported and imported. So for m point of view it is enough for now. Other logs that are missing is for example backup logs.

    @Forza I didn't try, as my default Graylog Input was UDP and worked with the hosts... But guys, that was it. In TCP mode, it's working. Rapidly set up a TCP input, and voila. [image: 1758137911306-42411fc9-af86-4838-a870-ca9ca6307234-image.png]

    @Andrw0830 I am using paid version of ESXi / vSphere. The free version of ESXi has so many limitations that I consider it pretty much unusable / only usable for very limited basic tests. It would not suprise me if your issue is due to the license limitations within ESXi.

    XOA suddenly "empty" during rolling update

    @Andrew said in XOA suddenly "empty" during rolling update: @halvor Yes, kind of... The pool master must be updated and rebooted first. If you move the master to a different host then you are no longer rebooting the pool master first. XOA is just a very smart client and needs the pool master to provide all of the pool information. Secondary machines will just redirect to the master, so if you try to connect XOA to one as a backup it won't work. You just need to wait for the master to reboot and return to a functioning state and wait for XOA to automatically reconnect. The everything will start happening again. If your master host is destroyed (ie. software corruption, hardware failure) then an existing host can be forced to take over the pool as master, but this is not a good thing to do unless the actual pool master is unrecoverable. Ok, great, thank you for clearing this up!

    @planedrop While you are connected to the XOA VM, be sure to verify that the required changes have been performed on /etc/systemd/system/xo-server.service when the VM memory was increased. Details can be found in this troubleshooting KB article -- https://help.vates.tech/kb/en-us/31/48

    I have no idea what this flag is doing, so my gut feeling is: no, it's not on XO side but a "problem "on the reverse proxy itself.

    @CodeMercenary Glad it worked! I just noticed that in the couple weeks since this happened, a new set of Pool Patches was available, so I ran through the usual process to update those and had no issues at all. This time, everything went smoothly, just as it has for the entire time I've had this lab up and running. So, chalk this up to one of those weird glitches you're bound to see when you use any technology long enough. As far as I'm concerned, the issue has been resolved. Please feel free to close out the issue.
