I find the model of pciback owning pass-thru'ed devices, configuring and
resetting them, and ultimately handing them off to domU guests via the PV
front-back interface or via qemu-dm emulation, is quite attractive at least
conceptually. As you say, I'm not sure what devils may lie in the details.

Still, it seems nicer than hacking logic into xend. :-)
