This guide is a variation of the standard Open vSwitch deployment guide
available at:
`<https://docs.openstack.org/openstack-ansible-os_neutron/latest/app-openvswitch.html>`_
We recommend that you read the following documents before proceeding:

neutron_plugin_type: ml2.ovs.dvr
neutron_ml2_drivers_type: "flat,vlan"
neutron_ml2_drivers_type: "flat,vlan,vxlan"
# Typically this would be defined by the os-neutron-install
# playbook. The provider_networks library would parse the
# provider_networks list in openstack_user_config.yml and
# generate the values of network_types, network_vlan_ranges
# and network_mappings. network_mappings would have a
# different value for each host in the inventory based on
# whether or not the host was metal (typically a compute host)
# or a container (typically a neutron agent container)
#
# When using Open vSwitch, we override it to take into account
# the Open vSwitch bridge we are going to define outside of
# OpenStack-Ansible plays
neutron_provider_networks:
network_flat_networks: "*"
network_types: "vlan"
network_vlan_ranges: "physnet1:102:199"
network_mappings: "physnet1:br-provider"
The overrides are instructing Ansible to deploy the OVS mechanism driver and
associated OVS and DVR components. This is done by setting ``neutron_plugin_type``
to ``ml2.ovs.dvr``.
**Note:** The only difference to the Standard Open vSwitch configuration
is the setting of the ``ml2_plugin_type``.
The ``neutron_ml2_drivers_type`` override provides support for all common type
drivers supported by OVS.
Customization is needed to support additional network types such as vxlan,
GRE or Geneve. Refer to the `neutron agent configuration
<https://docs.openstack.org/neutron/latest/configuration/#configuration-reference>`_ for
more information on these attributes.
For additional information regarding provider network overrides and other
configuration options, please refer to the standard Open vSwitch deployment

The overrides are instructing Ansible to deploy the OVS mechanism driver and
associated OVS components. This is done by setting ``neutron_plugin_type``
to ``ml2.ovs``.
The ``neutron_ml2_drivers_type`` override provides support for all common type
drivers supported by OVS.
If provider network overrides are needed on a global or per-host basis,
the following format can be used in ``user_variables.yml`` or per-host
in ``openstack_user_config.yml``.
.. note::
These overrides are not normally required when defining global provider
networks in the ``openstack_user_config.yml`` file.

The ``provider_networks`` library has been updated to support the
definition of network interfaces that can automatically be added as ports
to OVS provider bridges setup during a deployment. As a result, the
``network_interface`` value applied to the ``neutron_provider_networks``
override in ``user_variables.yml``, as described in previous Open vSwitch
deployment guides, is no longer effective. If overrides are
necessary, use ``network_interface_mappings`` within the provider network
override and specify the respective bridge-to-interface mapping
(e.g. "br-provider:bond1"). For more information, refer to the latest Open
vSwitch deployment guide.
