Thank you very much for reply. Initially my thought of uptime is equal to executing to `uptime` inside a virtual machine.  as for the second case, where virtual machine is paused for a period, does libvirt expose an api to get how long qemu process has existed?

No, it doesn't. But that should be pretty easy to implement into virDomainListGetStats()/virConnectGetAllDomainStats(). Alternatively, libvirt emits an event when a domain is started, so you may use that to record the time when the domain was started. Michal
