Per http://sayalilunkad.github.io/posts/Devstack/ By default the following services are enabled when you install OpenStack using Devstack: Nova (API, Certificate, Object Store, Compute, Network, Scheduler, VNC proxies, Certificate Authentication) Cinder (Scheduler, API, Volume) Glance (API and Registry) Horizon Keystone MYSQL RabbitMQ Tempest Additional services that are not enabled by default can be enabled in the localrc. Also disabling any service can be done from the localrc. Both localrc and stackrc can be found in the Devstack directory. Now we will see how to enable the other services in OpenStack. Some services that are not enabled by default are given below. Select the required service and add the respective lines to your localrc. Swift - Object Storage ENABLED_SERVICES+=,s-proxy,s-object,s-container,s-account Ceilometer - Metering Service ENABLED_SERVICES+=,ceilometer-acompute,ceilometer-acentral,ceilometer-collector,ceilometer-api ENABLED_SERVICES+=,ceilometer-alarm-notify,ceilometer-alarm-eval Neutron - Networking Service ENABLED_SERVICES+=,q-svc,q-agt,q-dhcp,q-l3,q-meta,neutron Heat - Orchestration Service ENABLED_SERVICES+=,heat,h-api,h-api-cfn,h-api-cw,h-eng
