If I understand correctly this just drives a simple PCI controller for a
PCI bus that a virtio device happens to be usually plugged in to, yeh?

It sounds like it would make sense to take advantage of Will Deacon's
recent efforts to make a generic pci controller driver for this sort of
thing which specifically mentions emulation by kvmtool? Is it
effectively the same PCI controller that is being emulated?
