Public bug reported:

The feature support matrix has a section for virt drivers that support
live migration:

http://docs.openstack.org/developer/nova/support-
matrix.html#operation_live_migrate

But the 2.22 microversion added support for forcefully completing a live
migration:

http://docs.openstack.org/developer/nova/api_microversion_history.html#id20

However, that's currently only supported by the libvirt driver, and even
then only in certain cases, like libvirt>=1.3.3, qemu>=2.5.0, and the
VIR_MIGRATE_POSTCOPY flag must be set.

We should, however, document that this is at least an operation people
can try to perform via the REST API and describe what it does and which
virt drivers support it.
