For some reason, “unknown” I can no longer start VMs using VFIO pass thru. It has been working flawlessly up till now. If I remove my video card I am passing through the VM starts.
when I start the VM the screen shows no error, attempts to start and immediatly stops. If I boot into windows, that particular card I am passing through works fine.
What I have tried:
reboots
updating
verifying vfio_PCI.ids is correct
verified grub line has not changed in last in 6 months
verified pci group is the same
verified iommu and vtd is on in system bios.
Any tips on what else to look at would be greatly apprecaited.
