Ok, reinstalled and re-tested. What I've learned:
- HA only works now if OOB is configured, the old way HA no longer applies - this can be good and bad, not everyone has IPMIs - HA only works if IPMI is reachable. I've pulled the cord on a HV and HA failed to do its thing, leaving me with a HV down along with all the VMs running there. That's bad. I've opened this ticket for it: https://issues.apache.org/jira/browse/CLOUDSTACK-10234 Let me know if you need any extra info or stuff to test.
