Re: how to get vm uptime through libvirt api
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,

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.
