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 ...

best,
Herbert

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