For this kind of work I would suggest trying 'vserver', it is a lot more
light wight then using UML.  You basically create very secure chroot
environments.  You can then create ip-tunnels so that each vserver can
have its own (faked) network interface.

Anyway, try UML, it seems a lot easier.  If you find it slow on your
hardware give vserver a try:
