Move DevStack OVN module to Neutron
This patch is moving the DevStack module to deploy OVN to the Neutron DevStack plugin. As a first step, this plugin will continue to use the openstack/networking-ovn repository and, as we advance into the mergings steps we will modify this plugin (just few lines) to use the code in the Neutron repository itself. TODO's where left in the code on top of all the bits that will change once the networking-ovn code is merged into Neutron. Below is a snippet of the what needs to be enabled in local.conf to get OVN deployed: [[local|localrc]] enable_plugin neutron https://opendev.org/openstack/neutron Q_AGENT=ovn Q_ML2_PLUGIN_MECHANISM_DRIVERS=ovn,logger Q_ML2_PLUGIN_TYPE_DRIVERS=local,flat,vlan,geneve Q_ML2_TENANT_NETWORK_TYPE="geneve" Partially-Implements: blueprint neutron-ovn-merge Change-Id: I24ab11ab923339959eecfbaed79a3ceadc4a87f4 Signed-off-by: Lucas Alvares Gomes <lucasagomes@gmail.com>
