Just to be clear, are you saying the CPU usage of the host OS does not reflect 
overall CPU usage of the guest VMs it hosts?

That's correct.

Ideally the dom0 wouldn't show a high load average, ever.  If it does, then it 
is likely taking resources away from the other guests.  The dom0 instance is 
there to manage the hypervisor and provide driver backend services to the 
guests for disk, network, etc.  None of those things should require much CPU 


I'm not talking about dom0 (Or maybe I am), I am logging into the host OS, is this the same as logging into the dom0 VM?

So if I look at TOP in the host SSH login am I just looking at the resources used by dom0?
