Hi,
This is v6 of virNodeGetCPUTimeParameters() API. (This time, I rename it to virNodeGetCPUStats()) It returns cpu utilization or cumulative cpu time of the node from /proc/stat since node boots up. This patch only supports linux host.
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, -Kame
