[Beowulf] vmware perfomance

Actually, I'd thought about this myself some: suppose I have a small
cluster, and a head node that I also use as a workstation (so I'd think of
the compute nodes as devices serving on my workstation, not of the headnode
as dedicated to fileserving as you'd have at the departmental level). So
then one might wonder, could VMWare running on the head make use of nodes
for some workstation applications; e.g. run an application on a node while
the head CPU does mostly GUI? I dunno, I've never used VMware (or kvm etc)
