Or Xen. Xen takes a different approach and runs a slightly modified Linux
(or OpenBSD, or several other things) in what they call "paravirtualization".
Xen has very very low overhead and also supports mildly insane things like
moving a running Linux image between two machines without downtime of any
We are actually considering using Xen2 at the moment on the image server
side for running the protosystem images. We've been coodrinating some
with the cluster dudes who are also interested in Xen.
