Create the tables in your backend data store by running the following command: $ sudo nova-manage db sync # 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. Note that if while running this command you see warnings such as SADeprecationWarning: The 'listeners' argument to Pool (and create_engine()) is deprecated. Use event.listen()., these will be fixed in future version of the libraries and can be safely ignored. Restart all services in total, just to cover the entire spectrum. On the controller node run: sudo start nova-api sudo start nova-conductor sudo start nova-network sudo start nova-scheduler sudo start nova-novncproxy sudo start libvirt-bin sudo /etc/init.d/rabbitmq-server restart # for svc in api objectstore conductor network volume scheduler cert; do sudo service openstack-nova-$svc start; done On the compute node run: sudo start nova-compute sudo start nova-network # for svc in compute network; do sudo service openstack-nova-$svc start; done All nova services are now installed and started. If the "start" command doesn't work, your services may not be running correctly (or not at all). Review the logs in /var/log/nova to look for clues.
