[Openstack] Recovering from full outage


Running `openstack server reboot` on an instance just causes the instance to be stuck in a rebooting status. Most notable of the logs is neutron-server.log which shows the following:

I realized that rabbitmq was in a failed state, so I bootstrapped it, rebooted controllers, and all of the agents show online.

And all of the instances can be properly started, however I cannot ping any of the instances floating IPs or the neutron router. And when logging into an instance with the console, there is no IP address on any interface.

Try restarting them using "openstack server reboot" and also check the nova-compute.log and neutron agents logs on the compute nodes.

We just suffered a power outage in out data center and I'm having trouble recovering the Openstack cluster. All of the nodes are back online, every instance shows active but `virsh list --all` on the compute nodes show that all of the VMs are actually shut down. Running `ip addr` on any of the nodes shows that none of the bridges are present and `ip netns` shows that all of the network namespaces are missing as well. So despite all of the neutron service running, none of the networking appears to be active, which is concerning. How do I solve this without recreating all of the networks?
