Thanks, I found out about the OVMF package for Ubuntu and added the
paths to qemu.conf.

I am able to start this virtual guest, but there is still no sign the
display try to init.

In part 4 of your guide you don't add the PCI pass-through devices until
the very end (after OS install). That shouldn't be needed, should it?

Can you spot anything wrong with this guest, or provide any other hints
as to where I should look?
