The main difference is that openstack-ansible uses more heavy weight
containers from a common base (ubuntu 14.04 currently, 16.04/cent
'soon'), it then builds on top of that, uses python virtualenvs as well.
 Kolla on the other hand creates the container images centrally and
ships them around.

The other thing to note is that Kolla has not done a non-greenfield
upgrade as far as I know, I know it's on their roadmap though.
