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.
