Well, this is interesting, are you currently exporting the file-based block 
device to the guest as a whole device, or as a partition?

If the latter, then you could just attach another file-based block device as 
another partition (just add it in the dom0 config and it should show up in 
the guest).  If the former then you'll need to either repartition your 
existing VBD (e.g. resize the filesystem in the current VBD) or add a new one 
then partition it from within the guest.

There are probably other ways of doing this too.....  With more information 
about your current setup it should be easier to give more specific 
suggestions.

Cheers,
Mark
