Hi，

I found you have a wrong configuration of "overlay_ip_version"  from ml2_conf.ini, you can check it ,  it could config to  "6" or "4". But I am not sure it is the reason for you problem.

Thanks,

Yun

Hi everyone,

I try to install OpenStack with OVN enabled. But when trying to start neutron-server, the service is always inactive (exited)

I try to check neutron-server logs and gets this message:

ovsdb-server port is active: https://paste.ubuntu.com/p/MhgNs8SGdX/

neutron.conf and ml2_conf.ini: https://paste.ubuntu.com/p/4J7hTVf5qz/

Does anyone know why this error happens?
