commit 770914f98df9abda2b5b8ca2896ff05618ea0181 Author: Lucas Alvares Gomes <[email protected]> Date: Tue Sep 12 11:36:59 2023 +0100 [OVN] Enhanced external port scheduling This patch introduces a new configuration for OVN CMS Options called "enable-chassis-as-extport-host". This configuration can be used by ML2/OVN to identify nodes that are eligible for scheduling OVN's external ports. Prior to this patch, external ports were always scheduled on centralized networked nodes tagged with the "enable-chassis-as-gw" flag in the OVN CMS Options but, when it comes to deploying OpenStack on OpenShift requiring services such as the OVN Metadata Agent or DHCP Agent to serve those external ports and running them on control plane nodes are not ideal. This is where this patch comes handy allowing these ports to have more flexibility in where they are scheduled. The patch is also backward compatible and if the new configuration is not present on the OVN CMS Options, ML2/OVN will continue to schedule the external ports on nodes configured with the previous configuration like always. Documentation will be updated on a follow up patch.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/2037294 Title: [OVN] Allow scheduling external ports on non-gateway nodes Status in neutron: Fix Released Bug description: Currently, external ports are always scheduled on nodes centralized networked nodes tagged with the "enable-chassis-as-gw" flag in the ovn-cms-options. When it comes to deploying OpenStack on OpenShift, requiring services such as the OVN Metadata Agent or DHCP Agent to run on control plane nodes are not ideal, ideally we would like to be able to deploy these services on EDPM compute nodes. This LP proposes adding a new configuration to ovn-cms-options to tag nodes eligible for scheduling external ports. This work should be 100% backward compatible and if the new tag is not present in any node, ML2/OVN should continue to schedule external ports on nodes tagged with the "enable-chassis-as-gw" configuration, just as-is today. Also note that, this work does not involve changing the L3 scheduler. The gateway ports are still going to be schedule as they are today using the "enable-chassis-as-gw" configuration. This work only affects the external ports.
