interestingly enough - playing around with Suse 10.1 and the yast2 based 
xen-vm-installer-thingy - I've found out that Yast attempts to do just 
that: install a brand new domU from e.g. a Suse CD. Not that I got that 
working but still I wonder if they found a way to achieve this 
paravirtualisingly. Any comments or experiences, Suse admins?
