Hi All,
I have a followup question on what Dan replayed.

When talking about CPU percentage is it out of the VM's virtual CPU(s) or is it out of whole VDS CPU(s)?

In case of "out of vm's virtual CPU(s)", what will be the best way to get my goal(calculating the VM cpu usage percent out of the total VDS cpus)?
I could count all virtual CPUS in the VDS host and calculate: (cpuUser+cpuSys)/(#cpusInVds*100)

Suggestions will be much appreciated :) 

Dan - 10x for your help

    vdsClient -s 0 getAllVmStats

provides cpuUser and cpuSys per VM. They represent the CPU percentage
used by this vm in user mode and kernel mode, respectively.
Note that percentage may be more than 100% for multi-processor VMs.

Yeah, I'm old. But you should not be shy; it's better to ask such
questions on vdsm-devel@fedorahosted.org so more people could answer and
more people can learn.
