title: How to get cpu cores utilizations in xen?
body: <p>I have installed <code>xen</code> as hypervisor and there are <code>dom0</code> and some paravirtualized machins as <code>domu</code> VMs on it.<br>
  I know <code>xentop</code> is used for checking the performance of system and virtual machines and I can read the output of it for measuring the virtual machine cpu utilization, But, it just gives the total usage of cpus!<br>
  <strong>So, is there any tool or any way to get cpu usages per cores?</strong></p>
