I had some vms created and working before my flash drive went bad.  replaced the flash, but now when unraid comes up, my vms will not start.

 

Device 'vfio-pci' could not be initialized

if I switch to vnc the system boots fine so it is obviously stuck on the video card for some reason

You most likely forgot to add the hotfix for the missing vfio devices in qemu.conf found here

The fix is for those of us that have more than 32 iommu groups. Your graphics card is in group 34.

you are correct.  I did not.  I saw mention of a hotfix last night, but never thought to install it.

 

now if only I knew the command to restart libvirt via ssh.

You can enable/disable it in settings --> VM manager.

Ah, makes sense. I was thinking that would want a reboot and I would have to run an actual command via SSH.

 

Thanks . back in business
