Hi,

Just a side note for Linuxbridge: linuxbridge driver was deprecated (see [1]) in Antelope (2023.1) cycle and even the code was removed in Epoxy (2025.1) cycle (see [2])

For migrating away from linuxbridge driver there was/is a discussion with etherpad also:

Hi,

Thank you for the warm welcome and your reply.

This is not an OVN-based deployment. It's a standard OpenStack-Ansible All-In-One (AIO) installation, using neutron-linuxbridge with the traditional neutron-l3-agent and neutron-l2-agent services. No OVN components are installed.

Everything else (including metadata, DHCP, and L3 agents) seems to behave normally. The issue appears limited to floating IP reachability, and affects VMs sporadically.

If you have suggestions for what I could check—specific logs, agent status, or perhaps a known bug or race condition—I’d be happy to dig further.

Thanks again for your time and support.

Best regards,
