Since this is replacing the existing pci passthrough code in both the
lxc and qemu drivers, I think we need both a line-for line comparison
and some real test time. I can do the code audit and some amount of
testing for qemu, but may be out of commission for the next 3 days. I'm
not sure about lxc. I also agree that we really need to get this in,
just so we can stop worrying about missing bugfixes that have been put
into the qemu hostdev code.
