Hello, KVM cpu consumption functionality is a bit lacking. KVM nor libvirt give this data and right now the cpu consumption is got from 'ps' command. This value is not the instantaneous consumption but the percentage the process was consuming cycles. We are planning to change the method to get this value in the near future.
Even if this value is not correct the scheduler will behave as there's also the notion of Available CPU (ACPU), that is, the CPU not reserved and this is not got from the monitoring script.
