      This is indeed not normal, could be a BIOS problem or even hardware problem (or a pretty bad bug in Xen?). What kind of hardware is it? I would be surprised to be server grade (or this points to a software bug then).

        @olivierlambert As I pointed out earlier, everything was working perfectly until I shut down to replace an NVMe stick, which involved moving around a couple of PCIe cards, hence changing their IDs for passthrough.

        It's a Supermicro X11DPH-T running a pair of Xeon Gold 5118. The BIOS was up to date as of the middle of last year, with a date of 3/5/24.

        Cheers.

              @olivierlambert Any further thoughts or suggestions (move PCIe cards around again ??).

              Cheers.

                      @EddieA Can you try differents combinations of passedthrough hardware in this VM ?

                      e.g try with each device one by one at a time; at least in the VM

                        Give me a couple of days to try. It is (obviously) down to the combination of devices passed through, as I reported this earlier:

                        said in TrueNAS VM failing to start:

                        Re-boot XCP and start the TrueNAS VM with NO passthrough devices. As expected, that started up fine.

                        Cheers.
