Quick summary: 
The problems was our HD is divided in two, and we wanted to use the unused 4GB 
in the on partition on the second. I found no way to do this with VM, 
although I was told it ought to be possible, Jonas sent the above included 
solution.

We solved this different: We made a new partition out of the remnaining 4 GB 
(hde7), and this way gave the server/us access to the the last unused parts 
of our harddisk.
