Hi all, After exposing mwait/monitor into kvm guest, the guest can make physical cpu enter deeper cstate through mwait instruction, however, the top command on host still observe 100% cpu utilization since qemu process is running even though guest who has the power management capability executes mwait. Actually we can observe the physical cpu has already enter deeper cstate by powertop on host. Could we take cstate into consideration when accounting cputime etc? Regards, Wanpeng Li
