Github user jayakarteek commented on the issue: https://github.com/apache/cloudstack/pull/1918 @rafaelweingartner we can retrieve the CPU speed of the host but the utilisation will have mismatch. create VM with Medium Instance having 1000 Mhz , and VM is utilising 200Mhz of CPU then utilisation is 20%. But if we consider host CPU capacity with 2400Mhz then utilisation in 8.3%. @nvazquez I checked CPUCounter API doc, even in this case values will have some missmatch. as per the below document with the usage formula they are using. https://www.vmware.com/support/developer/vc-sdk/visdk41pubs/ApiReference/cpu_counters.html
