We've looked at using UML.  While the description is similar, UML is not
the same kind of system as VMWare.
   - UML requires specially modified kernels
   - UML ties you to a single kernel and configuration
   - UML kernels are only usable in UML mode

VMWare creates emulated physical machines, which can run any kernel and
environment.

Running VMWare on compute nodes allows the cluster to run and manage
both native and alien (e.g. Microsoft) applications.
