Just to make sure I grasp this correctly.

We have PHBs that are VFIO PHBs and PHBs that are emulation PHBs. 
Emulation PHBs can only have emulated devices attached. VFIO PHBs can 
only have a single IOMMU group's devices attached each. A container can 
not span 2 different VFIO PHBs.

Is this correct? If not the code below needs to take care of any 
abstraction we have in between and maybe limit scope a bit to make sure 
the guest doesn't kill devices on other PHBs :).
