            Do you have BIOS access? I would double check you have various options enabled (I don't remember exactly which ones, also this bug rings a bell but I can't find exactly what πŸ€” )

              @olivierlambert I'll have a run through the bios shortly. I recall enabling all the virtualization settings etc. everything else seems to be running smoothly.

              my hunch is it is graphics related and BlueIris is probing for graphic accelerator hardware. I cant find a way to disable this behavior to test my theory though.

              Something similar was reported on proxmox, the solution was to set the following option, but I don't see an equivalent. For XCP-NG.

              echo "options kvm ignore_msrs=1" > /etc/modprobe.d/kvm.conf

                It's weird since we patched those recents CPUs for this bug: https://github.com/xcp-ng/xcp/issues/434

                Could it be something else? πŸ€”

                olivierlambert created this issue in xcp-ng/xcp

                closed Backport Xen patch to support Ice Lake and Comet Lake CPUs #434

                  @olivierlambert okay, I just remembered, I had trouble installing too ..... The install was black screening after relinquish VGA.

                  After some reading around I happened upon :

                  "Custom XCP-ng 8.2.1 install ISO with Xen 64bit VGA Dom0 kernel fix (NUC11) and new ethernet drivers (NUC10/NUC11):" from here :

                  https://users.ntplx.net/~andrew/xcp/

                  This is how I got up and running.

                  I'm way out of my depth here, but this feels like it might be the crux of the matter.
