I have a RFC version of replay implementation that used the way to do
it (each device will have its own address space, even if more than one
devices are in the same IOMMU domain). I'll arrange the patches and
post soon. Let's see whether that's a valid approach to fix existing
issues for vfio enablement on vt-d.

Thanks,
