libvirt interface. Is there a way get this info now for all the
aforementioned hypervisor types?
The APIs virConnectGetSysinfo(), virNodeGetInfo() provide host info but
it doesn't include the system uptime.
Afraid we don't have any reporting of the "uptime" yet - feel free to
report a bug against libvirt asking for this, or if you are C coder
we'd accept patches too.
The virNodeGetCPUStats() can returns CPU usage in nanosecond, can we
add
the user + system + idle + iowait to calculate the system uptime? Looks
like the sum value has a huge gap with the real uptime value returned
by "uptime" CLI.
Yeah, I'm not sure that's going to be reliable.
