Jay, is your use of the wording "behaviour that Nova supports" there,
significant? I mean, you're not trying to indicate that Nova does not
support _live_ migration, are you?

Anyway, I found this relevant and stale bug:
https://bugs.launchpad.net/nova/+bug/883845. VIR_MIGRATE_LIVE remains
undefined in https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py.
We only just discovered the lack of this as a default option, so we'll
test further, this time with VIR_MIGRATE_LIVE=1 explicitly specified
in nova.conf...
