Create the tables in your backend data store by running the following command: sudo nova-manage db sync If you see any response, you can look in /var/log/nova/nova-manage.log to see the problem. No response means the command completed correctly and your nova database is now populated. On both nodes, restart all services in total, just to cover the entire spectrum: sudo restart nova-api sudo restart nova-compute sudo restart nova-network sudo restart nova-scheduler sudo restart nova-vncproxy sudo restart libvirt-bin sudo /etc/init.d/rabbitmq-server restart All nova services are now installed and started. If the "restart" command doesn't work, your services may not be running correctly (or not at all). Review the logs in /var/log/nova.
