[vdsm] Fwd: Calculating the VM cpu usage percent out of the total VDS cpus

```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
