Hi Followed your open stack installation juno guide and successfully done with the same. Now we are trying to launch an instance but getting an error. Please provide the solution ASAP. Just for the information we haven't configure cinder. We only configure keystone, nova, neutron, glance. Following are the configuration of our OpneStack Setup. Controller node - keystone, mysql, rasbbitmq, and remaining recommended nova and neutron api. Neutron node - neutron service compute - nova service PFA Screenshot .
