Try xm top and other xm commands as xm list.

or xl top if you're using the new xl toolstack. It actually just calls xentop though. – Matt May 2 '12 at 23:39

Some versions of virt-manager give you a sum of all loads as the load of the Dom0. What exactly do you want to know?

I dont think i can use virt manager, i do not have any gui installed on the host. it is a pretty clean debian install. What i want to find out primarily is how much cpu is used. Running htop on the host machine would do. – Joelbitar Apr 8 '11 at 16:58
htop and top will only show the load of the Dom0 system. This is propably not what you want, since your running DomUs add to the load on your real CPUs. So do you want to see the total load on your real cpus or just the Dom0 load of its virtual cpus? – Nils Apr 8 '11 at 20:18
I want to se the total load of my real cpus – Joelbitar Apr 11 '11 at 8:33
then maybe top is what you're after? – Matt May 3 '12 at 1:00
@Matt propably xentop. But is seems like Joelbitar has lost the interest in his own question. – Nils May 3 '12 at 20:09
