This is a bug then. You should be able to boot without XENHVM/xenpci,
and get a pure HVM guest with no PV devices at all.

Since this seems to be getting quite popular (booting without PV
devices), I think adding a sysctl to disable PV nics and PV hard drives
would be interesting. We could still use some of the PV goodies, like
the timer.

I will deal with this ASAP.
