Please see the other patch, I copy/pasted the wrong text! On Wed, 2020-10-07 at 13:50 +0100, Steven Newbury wrote:

When using a passthrough GPU with libvirt there is no option to pass "x-vga=on" to the device specification. This means legacy VGA support isn't available which prevents any non-UEFI cards from POSTing and prevents some drivers from initialising for example Windows 10 NVIDIA driver for GeForce 8800.
