I've measured the cpu load by using "top" linux command. I've also tried 
with some monitoring tools like Munin/Collectd but I always get weird 
values. All these monitoring tools were running on a linux fedora 
machine with xen kernel and with xen up and running.
The question is: using "top" on the physical machine with xen dom0 up 
and running will provide me the usage of the dom0 process?
Of course, what I need is the cpu load of the real machine.

Am I doing it wrong?

Thanks,
M
