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::
