Use video=efifb:off,vesafb:off to disable both efi and non-efi framebuffer drivers. > qemu-system-x86_64: -device vfio-pci,host=00:02.0,addr=02.0: IGD device > 0000:00:02.0 has no ROM, legacy mode disabled > Hopefully the above will fix this. > Could not initialize SDL(No available video device) - exiting > You need a -nographic option to avoid this.
