Thanks for the problem report, Peter. Yep, so you
are using the recently added PCI passthrough stuff?

We have not yet added any tests for that environment
or looked into it yet. Would be good to add that case
to an xm-test configuration. Will let you know once
we get to that one.

At the moment, our assumption has been that the physical
NICs are in dom0. There is probably other stuff to shake
out in driver domain support.

thanks,
Nivedita
