I think this is probably because your kernel has PVHVM (PV drivers for
HVM guests) enabled, so the IDE devices are unplugged and a PV path is
used instead, which converts hd[a-d] into xvd[a-d].

I think it's probably an expected behaviour related to the unplugging,
although I'm not quite sure what ;-)
