​Hi Troy,

In order for you to start ovn youself, you need to do the below

1. Create initial ovn nb and sb dbs using ovsdb-tool
  $ovsdb-tool create /opt/stack/data/ovs/ovnnb.db
/opt/stack/ovs/ovn/ovn-nb.ovsschema​

​
$ovsdb-tool create /opt/stack/data/ovs/ovnsb.db
/opt/stack/ovs/ovn/ovn-sb.ovsschema​
 ​

  Please change the path as per your wish.

  Refer this link for more information -
https://github.com/openstack/networking-ovn/blob/master/devstack/plugin.sh#L193


2. Start ovsdb-servers.

3. Start ovn-northd and ovn-controller.

Refer this link on how to start these services -
https://github.com/openstack/networking-ovn/blob/master/devstack/plugin.sh#L259

The script file devstack/plugin.sh has answers for all your questions I
guess :).

Thanks
Numan
