Can I make a question ?
What "CPU' means here ?
CPU usage statistics from the Guest OS's point of view ?
Do we get the information by asking an daemon or module on the guest
to gather statistics on the guest ?
No.
This API gets host cpu statistics, not guest.
It's just read statistics from /proc/stat of the host.
Thanks,
