We're not yet on 24.04 and still have a few OpenStack upgrades to do before we can try 24.04. For now, we're running 22.04 and do specify the bridges that neutron-linuxbridge-agent would create directly in systemd- networkd, which mostly works, like this:
# /etc/systemd/network/10-brqe240c66b-da.netdev [NetDev] Name=brqe240c66b-da Kind=bridge MTUBytes=1500 # /etc/systemd/network/10-brqe240c66b-da.network [Match] Name=brqe240c66b-da [Link] MTUBytes=1500 [Network] LinkLocalAddressing=no ConfigureWithoutCarrier=yes This might have some implications on security, since we're not completely sure that we didn't miss any isolation or brtables/iptables rule that neutron-linuxbridge-agent would or wouldn't set up, but in our specific case, we deemed that as acceptable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2004179 Title: neutron-linuxbridge-agent flat network incompatibility with systemd- networkd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/2004179/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
