Description

from https://docs.openstack.org/neutron/latest//admin/config-experimental-framework.html

Of course, the Neutron core team would love to return experimetal features to the supported status, if interested parties step up to maintain them. If you are interested in maintaining any of the experimental features listed below, please contact the PTL shown in the Neutron project page.

This driver seems to still work in Z (codfw1dev is running it) but this seems bad! We need more research about what this means and what the alternatives are.

This has been known for years. We should [plan to] migrate off the linuxbridge agent.

I think nowadays the default for new openstack deployments is to use the openvswitch agent (see https://docs.openstack.org/neutron/latest/install/ovn/manual_install.html). But AFAIK, there is no direct migration path between the two, because they instrument the virtual <-> actual network in different ways.

Perhaps the cleanest to migrate to openvswitch would be to create a new deployment from scratch and the relocate all the workloads.

@arturo, I figured you were on top of this but didn't want to just ignore the notice. If this is known and documented elsewhere we can close this task.

Reopening, to help us keep in the radar we need to migrate off neutron-linuxbridge-agent.
