Well, I take back comment #4, the aggregate (AZ) didn't disappear, the error message was just vague.

Cannot add host newton to aggregate: meant that the host newton didn't exist, not the aggregate.

Looking over /var/log/nova/nova-compute.log on neutron, we see it failed to initialize a connection to libvirt and as a result didn't register newton as a compute host.

I'm still having trouble determining what caused the libvirt connection to fail on newton.
