Best practice is to use shared storage and then the "copy" is really only

Take a look at the nova release notes from that time forward and you should
see reference to the change(s).

about your environment (and maybe not even then.) This functionality is
very dependent on your specific configuration regarding:
and is also very dependent upon
nova structure (regions AZs, etc.)
