Hi all, I am looking to develop an openstack bundle which uses OVN as the SDN. I have been reading : https://docs.openstack.org/charm-guide/latest/ I have also read : https://docs.openstack.org/networking-ovn/latest/install/ index.html As far as I understand, this will require me to replace the "neutron-openvswitch" charm in the openstack base bundle. However, I am not able to exactly understand what all I will have to rewrite / replace to make this work. I know I need to make neutron work only as an API instead of the full blown SDN. Also, in the above doc, its mentioned that we have to run some setup on "controller nodes". How does the term "controller node" map to the openstack base charm? Some guidelines as to what to read about and help in understanding the already existing openstack charm would be great. Thank you for helping out, and sorry if these doubts seem trivial.
