Re: [libvirt] How to get iteration time & downtime?
Jiri thank you, and I will attempt to do some research using virDomainGetJobStats API.
Any stupid questions I will ask you later if necessary. :)
Best wishes,
Yale Yuan

Hi all,
I'm a graduate student in Shanghai, and will do experiment about live migration using
KVM as hypervisor.
Due to my demand, I want to get each iteration time and downtime in migration.
I found there is no API to implement it, and how can I obtain data I want?
Libvirt provides virDomainGetJobStats API which gives you all migration statistics data
provided by QEMU (via query-migrate QMP command). If you need something more, you would
need to add reporting of the required additional statistics to QEMU first.
