   Hi,

No.  Just don't do this silly if/bus/unit parsing.  At very minimum use 
drive_get_by_id() here, then have something like 'drive_del $id'.

IMHO much better would be to go qdev instead though.  We should have 
generic device_add + device_del monitor commands which work for any 
device, pretty much like the -device command line switch.

cheers,
   Gerd
