Real disklabel in domU (when using sysinst)

[Juan RP <juan%xtraeme.nopcode.org@localhost>]

Hi, I think we'd have to fix the problem with sysinst in the partition menu, 
because
first time it runs, the real disklabel is merged with the virtual partitions... 
can we use
an empty disklabel for xbd*? it should be clearer, and the user won't need to 
know
that he should to remove the 'physical partitions' in there.

Thanks.
