Here are instructions on how to use Devstack with the latest code from Manila to begin using Manila.
This procedure was tested and working as of 25 Feb 2015.
1. Clone devstack
$ git clone https://github.com/openstack-dev/devstack.git
2. Copy the sample local.conf into the root devstack directory
$ cd devstack ; cp samples/local.conf .
3. Edit/append local.conf to enable manila, and neutron, and to disable horizon, heat, and nova-network
$ cat << EOF >> local.conf disable_service horizon disable_service heat disable_service h-eng disable_service h-api disable_service h-api-cfn disable_service h-api-cw disable_service n-net enable_service neutron enable_service q-svc enable_service q-agt enable_service q-dhcp enable_service q-l3 enable_service q-meta enable_plugin manila https://github.com/openstack/manila Q_PLUGIN=ml2 ENABLE_TENANT_VLANS=True ML2_VLAN_RANGES=physnet1:100:200 PHYSICAL_NETWORK=physnet1 OVS_PHYSICAL_BRIDGE=br-eth1 Q_ML2_PLUGIN_MECHANISM_DRIVERS=openvswitch Q_ML2_PLUGIN_TYPE_DRIVERS=vlan,vxlan EOF
4. Run stack.sh as normal; When it is complete, the manila processes should be started.
