There has been talk on the lists before about either making this configurable or having two separate cpu metrics, real & virtual. Has anyone created a patch that does this yet? If not, then it should probably be added to the TODO list since this issue keeps coming up on the lists. Actually I just noticed that ganglia doesn't have a TODO list, perhaps we should make one to keep track of requests like this.
