Change subject: report cpuUser and cpuSys separately
......................................................................
Patch Set 1:
Here's the cpustats of a running vm:
virsh # cpu-stats 3
CPU0:
cpu_time 152.626922854 seconds
CPU1:
cpu_time 460.343462849 seconds
CPU2:
cpu_time 37.569566994 seconds
CPU3:
cpu_time 21.092908393 seconds
Total:
cpu_time 671.632861090 seconds
user_time 3.440000000 seconds
system_time 18.380000000 seconds
You can see cpu_time is much bigger than the sum of user_time and system_time,
because the guest time is not reported here. So most cpu time is used to run
guest code. It makes sense! For a qemu-kvm process, user_time represents the
time used by qemu, and system_time represents the time used by kvm module,
which doesn't contain guest time. I am not sure if this is what you expect. It
could be a little bit confusing for user.
