OVN provides open source network virtualization for Open vSwitch (OVS).
The neutron-api-plugin-ovn charm is a subordinate charm that augments Neutron's
configuration for use with the OVN ML2 driver. On OpenStack Ussuri and onwards
the OVN ML2 driver is maintained as an in-tree driver in Neutron. On OpenStack
Train it is maintained separately as the networking-ovn plugin.
OVN makes use of Public Key Infrastructure (PKI) to authenticate and authorize
control plane communication. The charm requires a Certificate Authority to be
present in the model as represented by the certificates relation.
The OpenStack Base bundle gives an example of how you can deploy OpenStack and OVN with Vault to automate certificate lifecycle management.
Please refer to the OVN Appendix in the OpenStack Charms Deployment Guide for details.
To deploy (partial deployment of linked charms only):
juju config neutron-api manage-neutron-plugin-legacy-mode=false
