Feature 'linuxbridge' is experimental

everyone

When deploying the openstack zed version, I found that the neutron could not be started. I checked the log and found the following error. What is the reason for this?

Error message： 2022-10-20 09:53:46.138 1769211 ERROR neutron.common.experimental [-] Feature 'linuxbridge' is experimental and has to be explicitly enabled in 'cfg.CONF.experimental'

The error seems reasonably clear: you are attempting to use the linuxbridge driver in Neutron, and this feature is now considered experimental. You must explicitly enable support for experimental features to use it.

From the docs about experimental feature support:

Some Neutron features are not supported because the community doesn’t have the resources and/or technical expertise to maintain them anymore. As they arise, the Neutron team designates these features as experimental. Deployers can continue using these features at their own risk, by explicitly enabling them in the experimental section of neutron.conf.

And from this bug report, dated 2022-07-07:

tl;dr neutron now considers linuxbridge which uses to be the default mech driver in docs to be experimental and it is now guarded by a config flag.

It looks like your options are either (a) enable support for experimental features, or (b) choose a different mechanism driver (e.g, openvswitch) .
