Well, that didn't work either.  I found some info in xend.log (see
below) and tried following the trace but I'm not a python programmer and
so don't understand some things.  I think the line which reads
'exception looking up device number for hd0: [Errno 2] No such file or
directory: '/dev/hd0''
is the key.
