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
qemudDomainMigratePerform
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?
Any pointers or suggestions will be greatly appreciated.
Regards
