Hi,

Yes, I fix it yesterday, sorry for not reporting it. The error is not in the configuration but in the crudini script.

Thanks

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:
