I don't think OVMF cares if a PCI device is pass-through or not. Does
the VM works with bios=seabios ?

There is maybe somethings wrong with the way OVMF handles PCI devices
that doesn't work with pass-through.

Håkon, could you add the following in the VM config? With that, we could
get some logs from OVMF:
device_model_args_hvm = [
  '-chardev', 'file,id=debugcon,mux=on,path=/tmp/OVMF.logs,',
  '-device', 'isa-debugcon,iobase=0x402,chardev=debugcon',
]
(Feel free to change the path.)

Thanks,
