Hi, I wonder if anyone mind explaining how we can measure live migration duration. I’m conducting some straightforward experiment on an small Openstack deployment on three nodes regarding performance interference of VMs & I wanna take into observation this metric too. What I got so far searching is to ping the migrating VM therefore we'll be able to calculate the downtime period somehow but not the whole procedure of migration! Any tools or method for that?

Thank you in advance.

The nova-compute log on the source host should tell you when it starts and when it ends. Also, there is a nova CLI command nova migration-list, which shows current and past migrations and contains timestamps.
