Actually, it works like everyone expects. In case of KVM you can just take a look at running instance with ps xa. But, I don't recommend setting CPU cap, though... VM will experience CPU steal, and users will not be happy. Better to deploy nodes with low cpu frequency and many cores.
Without capping, the frequency is only for the resource calculation, when VMs are deployed, specifically: node.core-freq > freq && aggregate-node-freq-avail - cores x freq > 0 -> permit сб, 2 мар. 2019 г., 13:51 Fariborz Navidan <mdvlinqu...@gmail.com>: > Hi, > > I am wondering how the cpu time usage is calculated for a VM.
