    For what I know, but maybe @teddyastie could confirm: Nothing. Typical of consumer grade hardware with buggy BIOS. Not I'm aware of No because it's a classical thing for consumer grade hardware. If you want zero message go for Dell servers. Even HPE server got sometimes buggy ACPI or stuff like that, but it's often patched during the life of the product. Consumer grade manufacturer simply don't care. Get server grade hardware or convince Asus to get their shit done correctly. Good luck on the latter (sadly).

    @dthenot said: @probain Hello, It's likely linked to the List index out of range bug. That bug was linked to the SR scan failing to introduce CBT_metatadata VDI in the XAPI database, could you try to launch a xe sr-scan uuid=<SR UUID> and try again to disable CBT? If it does not work, could you share the /var/log/SMlog of around the time you are trying to disable CBT? I've sent you a DM for sharing the logs.. Unfortunately I "solved" the issue by deleting all snapshots related to each VM. Including CBT ones. That did make it so I could toggle CBT on the VDIs again. But I've collected the logs for you. This also seems like a good time to raise my suggestion to have somewhere at vates where we could upload details in a similar way to how TrueNAS does it.

    @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?
