A more reliable setup uses the OVMF firmware. After that, I keep getting Unable to power on device, stuck in D3. I’m only able to run the passthrough VM once per reboot. The above script works, but not consistently. And I finally get the score right: Getting some frags in the VM at 200 fps About OVMF The result is virtually indistinguishable from bare metal. To pass through my USB keyboard, I use -usb -device usb-host,vendorid=0x04d9,productid=0x0192. You might also want to pass through keyboard and mouse to the VM.The approach with driver_override and modprobe has been more reliable for me. I struggled to get manual bind and unbind working, as described by Greg Kroah-Hartman.After qemu terminates, you will want the script to unbind vfio-pci and rebind the host device drivers.

x-vga=on seems to be required if you’re using SeaBIOS (as we are above).

Both need to be unbound from their drivers before passing them to the VM via -device vfio-pci.

Before I venture on to other areas such as VMware drivers/Spice-QXL and so, is there any way to sort things out with the regular vga device Thanks, Adam.

In my system, $GPU and $GPU_AUDIO (the HDMI audio controller) are the only members of IOMMU group 13. I have no idea what QEMU is emulating and so the device remains unrecognized in Windows, which, I suspect, leads to quite poor responsiveness.

When the guest boots up, it has full access to the host GPU: Until you get a reliable script, you will want to test this over SSH.

The para-virtualized virtio-gpu driver scales up to 4096x2160 and can adjust resolution to match the QEMU window. The moment you unbind amdgpu, the host becomes headless. qemu-system-x8664 \-enable-kvm \-smp 4 \-m 8G \-vga virtio \ ubu.qcow2 This is where things start to get interesting.
