Its a dual socket quad core amd. So I have 8 cores. cpus for dom0 is set 
to 0 and according to xend-config.sxp that will give dom0 access to all 
cpus. I havent adjusted any weighting so im not sure what would be 
stepping on it. The only thing running during the test was that one 
domU. and the domU was idle when running the test on dom0.
