==========================================
Ironic multitenant networking and DevStack
==========================================
This guide will walk you through using OpenStack Ironic/Neutron with the ML2
``networking-generic-switch`` plugin.
Using VMs as baremetal servers
==============================
This scenario shows how to setup Devstack to use Ironic/Neutron integration
with VMs as baremetal servers and ML2 ``networking-generic-switch``
that interacts with OVS.
DevStack Configuration
----------------------
The following is ``local.conf`` that will setup Devstack with 3 VMs that are
registered in ironic. ``networking-generic-switch`` driver will be installed and
configured in Neutron.
