      is there any explanation for the below results? I am getting results for cpu.usagemhz . There is always a difference between sum (vm1+vm2) and the value for the entire host.

    according to



    if i read this correctly the cpu usage mhz for host is sum of all cpu usage for vms that it hosts. In the below screen there is  292 mhz difference. Is there any explanation for this ? The documentation does not say anything about any hidden usage for example that the host itself also needs cpu on its own and this (in my understanding) is not covered by this metric.
