Upstream PV on HVM save/restore should be fixed, I am afraid this could
be a bug left in the RHEL6 PV on HVM kernel.

This should be easy to fix, probably a parsing error somewhere in xl.

I haven't seen any of these bugs recently. Are you still able to
reproduce them or are they just old bugs left open in bugzilla?

Assigning multiple devices to an HVM guest using qemu should work,
however assigning multiple devices to a PV guest or an HVM
guest using stubdoms is known NOT to work. In particular this is what
IanC is working on.

Is this bug being reproduced using stubdoms? If so, this is a known
issue, otherwise it might be a new bug.
