 this page demonstrates it best:

 http://www.cl.cam.ac.uk/Research/SRG/netos/xen/performance.html

 also, UML, unless it is patched (yes someone has provided
 such patches), provides the host running the UML linux apps
 with direct access to their kernel memory - for debugging
 purposes, obviously.

 i'm evaluating xen as a means to run applications like mozilla
 in an isolated selinux machine (!) also to suspend them down
 to disk, and use xen to start an entire virtual machine up
 when a user needs to run the application (!)

 my only concern is how to stop absolutely anyone from running
 a xen guest OS: management of xen is done on port 8000.
