After searching on the internet for a long time, I could not find clear answers to the questions below. Hence, I am posting my questions here.

Does OpenStack support live migration of a VM from a host in one availability zone to a host in a different availability zone ?

Also, does OpenStack support live migration of a VM from a host in one region to a host in a different region ?

Across availability zones: yes.

Across regions: No, since two different regions have two different Nova installations. You can only live-migrate within the same Nova installation.

How is migration across AZs supported? My scheduler keeps complaining about this, cf. my question.
