Deploying networking-baremetal and multi-tenant networking with DevStack

DevStack may be configured to deploy networking-baremetal Networking service plugin together with networking-generic-switch for multi-tenant networking. It is highly recommended to deploy on an expendable virtual machine and not on your personal work station. Deploying networking-baremetal with DevStack requires a machine running Ubuntu 14.04 (or later) or Fedora 20 (or later).

Create devstack/local.conf with minimal settings required to enable networking-baremetal with ironic and networking-generic-switch for multi-tenant networking. Here is an example of local.conf:
