On the usability/stability front, in nova you still can't correctly live-migrate
if you have dedicated CPUs or hugepages, or a specific NUMA topology. The
commits for this have been under review since Kilo, but never quite make it in.
At the same time, there are no warnings or errors to the user saying that it's
not stable...it just migrates and hopes that it doesn't collide with another
On the usability front, the new "openstack" client doesn't support
microversions, which limits its usefulness with nova. (I think some folks are
starting to look at this one.)
