Host 1 updated no issues. vms stopped migrated off host 2 to complete updates. Support ticket opened - Ticket#7758427. Found 1 vm with cpu stuck at 100% and unresponsive. Force rebooted vm and proceed updates on host2. Well I think i found the source of my problems. After having continues other odd issues with this remote pool. I decided i was going to reboot everything. That's when every vm started to fail. Logged into Synology rs1221+ and it was just very sluggish and not responsive. No new error alerts or anything to explain the odd behavior. Rebooted it and even after boot still odd behavior until finally disk error. Then the system started to respond. Luckily I have a spare drive onsite but cant gain access until Monday possibly Tuesday. Fingers crossed. Lucky for backups. Looks like the important vms had a successful backup as of yesterday so thats good. Still having issues with this remote pool. Synology is still rebuilding the storage pool, but the time seems unreal to complete 80+ days. It keeps dropping and increasing... Yet I tried to migrate vm from NFS SR to local storage and vm having issues boot. Try to determining but i think i have multiple issue just not sure which ones.

    @MathieuRA said: @acebmxer Hi i am able to reproduce the dashboard issue locally now, so we can also investigate on our end. Can you confirm, no dashboard issue on the commit : ee53cd072304a38e8bf816dceef9bc7277b776dc? Current commit running - Master 5811d Current available - Master a9f85 Should i update to the latest or do you have a specific build/branch to try?

    @laszlobortel since we are generating the stream sequentially, we though that there wasn't any real world gain. Also, if my understanding is correct using one thread means we will have only one process( + xo + nbdkit-vddk) processes , and we were trying to limit the risk of zombie process locking the disks , which was far too common with the previous code we'll do a quick test to ensure it does not beak anything and propose either a better default of a configuration option note that this will be a concurrency per disk, so VM with a lot of disk will put more pressure on the source

    @tsukraw I think the bottleneck is indeed the tapdisk and smapiv1. We have full 10Gb WDM between nominal and DR site, and get the same transfer speeds as you on CR. [image: 1779779566351-c860aa15-c649-4608-91f9-0cec88645218-image.jpeg]

    When speaking to our Veeam sources, we were told end of July is the target date for 13.1. That is what we are hoping for as Veeam is an important one for us.

    @tjkreidl I found that some Intel PRO GPU card have SRV-IO without any additional license, but this functionality is supported in Linux kernel 6.12 and up. I hope in new XCP-NG will have 6.12+ and support GPU sharing.

    @Rod-G These have 9.4.2-xxxx and I need to go through and update everything now that I see how far behind I am. the second VM completed fine after its reboot, something was just stuck in a dirty state and got in the way of the import or health check.

    @Danp I was going to do the upgrade over the December / January Christmas break in Australia but that is when this issue became apparent so we didn't want to be making major changes until it was resolved. I note @anthoineb noted the first report was late August / September 2025 which was just before 8.2.1 reached EOL, so it would be a shame not to have a fix for it tested on 8.2.1 as it seems an upgrade to 8.3 would be unwise while we still have this issue?

    @florent said: where does this disk comes from From my Redhat 10 @florent said: if you have access to your SR from the outside, you can also put the qcow2 file directly I create a VM to be a NFS to access the 3 HDs, the qcow disks are on the Redhat 10 that I was trying to import from. Do you mean I put the qcow disks on one of the HDs and access them when I create a VM?

    @pierrebrunet sorry for the delay in responding... I scored some time out of the office. Before replying, I rebuilt the XO server using the latest version and created a new backup identical to the last. Just wanted to be sure this issue wasn't fixed... I've attached the log. 2026-05-20T21_41_04.958Z - backup NG.json.txt
