Recommended PCI Passthrough options for VF's

[markednmbr1]

What is the recommended way of passing through vfs with kvm?

Should we use OVMF (for UEFI) or Seabios?

Should it be PCI-E (pcie=1, machine type q35) or old PCI?

Can we use x-vga=1 to make the VF the primary display of the VM? (this hasn't worked so far in my testing).

Thanks! This is probably something that should be in the docs, imo.

And additionally to my previous question, what is the correct driver to use? The one that is 17.12.2 and says it is specifically for GIM "technical preview" or the most recent driver?
