==========================================

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.

||||
