I have a basic question. I would like to know the best way to find out the CPU utilization in Xen. For example if i have a setup with Dom 0 and Dom 1 and some partitions are exported to Dom 1. When i perform IOs in Domain 1, since the actual disk device is under the control of Domain 0, the backend driver will be responsible for the actual IO operation completion. So it's obvious some amount of CPU will be utilized in Domain 0. In this scenario, i would like to know what is the best way to identify the consolidated CPU utilization both in Domain 0 and Domian 1. Is there any tool available which does this?
