hmm, just wanted to mention that linux-vserver has around 0% overhead and often allows to improve performance due to resource sharing ...
basically it's a soft partitioning concept based on 'Security Contexts' which allow to create many independant Virtual Private Servers (VPS), which act simultaneously on one box at full speed, sharing the available hardware resources.
see http://linux-vserver.org for details ...

PS: UML and Linux-VServer play together nicely ...
