Yes, quite right. It turns out Nova is not passing/setting libvirt's
VIR_MIGRATE_LIVE when it is asked to "live-migrate" a guest, so it is
not proper live-migration. That is the default behaviour unless the
flag is added to the migrate flags in nova.conf, unfortunately that
flag isn't currently mentioned in the OpenStack docs either.
