However the automatic evacuation of instances, or migration of instances wouldn't be handled by OSA or anything that OSA deploys. I hope that helps! If you have any more questions, or need further help getting set up with OSA feel free to drop by the #openstack-ansible channel on Freenode IRC. Thanks!
