Hi Alex, Yeah it seems you're right, the qemu command has "-device vfio-pci,host=01:00.0,id=hostdev2,bus=pci.0,addr=0x2", so it seems it is using vfio-pci.Thanks for the information.
One more quick question: I'm using SeaBIOS for my VM. My GPU doesn't support UEFI Secure/Fast booting. Can I use a GPU like this with OVMF and more importantly, is there any performance difference using OVMF over SeaBios?
