​Hello,

I have been trying to track different phases of a live migration process. I am using libvirt ​with qemu-kvm. I am issuing migration commands using virsh.

Now, I want to measure the time spent in each phase of live migration, e.g., pre-copy and stop-copy. I stumbled upon the file qemu_driver.c. It has functions like

qemudDomainMigratePrepare2

qemudDomainMigrateFinish2

I want to know whether qemudDomainMigratePerform and qemudDomainMigrateFinish2 directly map to the pre-copy and stop-copy phase? or the qemudDomainMigratePerform function performs both of them?
