thank you very much for reply. I have got another question which is off topic. Am I able to get vm's process id through libvirt api? Thank you very much. Best, Norman On Tue, Jul 26, 2022 at 4:04 PM Michal Prívozník <mprivozn@redhat.com> wrote:

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.
