Most of my clients run V stuff for the purpose of running more V machines
than they have physical servers.
Sharing resources (V) is a recipe for variable response time, which is a
major (perhaps THE major) cause of complaints regarding production servers.
Ergo, most of my clients do not run V for production, because they don't
share physical resources for production.
If you want a measurement for the OVM overhead on your machinery, then do
the same test with and without OVM.
One thing I know you don't want to do: mix para-virtualized and fully
virtualized machines on the same box.
