monitoring hypervisor / VMs

Is there any recommendations on how to monitor the system on the hypervisor level?

Anything else in addition to xentop? To get performance metirics in a file?

Also I am struggling to interpret monitoring results:
I have a hypervisor machine with 32 CPUs (SUN FIRE X4170 M3, OVM 3.2.1) and have one 4-cpu machine running there. Monitoring the VM under load (OEL 5) I see about 50% cpu utilization (about 2 cpus). In xentop cpu utilization is 300% (for this VM - 3 CPU?). Why these two metrics don't match? Any idea? Nothing else is running on this machine.

Thanks,
Alex
