@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.

@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

@olivierlambert XCP-ng Host 8.2.1

@olivierlambert xo-server 5.102.0 patched. Not nested.

A migrated VM is crashing my new hardware. If I do a clean install and run certain progammes (BlueIris) it crashes the VM. I think it is happening when software on the OS is probing for certain capabilities.

This issue from a few years back looks similar to the one I'm facing :
https://xcp-ng.org/forum/topic/3517/windows-10-vm-reboots-when-starting-software/18

which makes me think it is perhaps specific to my more recent CPU / hardware.
I'm using an N5105 processor.
