開発中バージョンのリリースノート

27.0.0-42

新機能

  • Add the extension extraroute-atomic to the ML2/OVN router plugin. This extension does not require any specific implementation.

  • An new option name trunk_enabled has been added to neutron-openvswitch-agent under OVS group. This new option can be set to False in order to disable loading the trunk extension on agent side. The default value for this option is True to keep backward compatibility with previous deployments. The recommendation is to set this option to False if you do not use the trunk extension, so that the number of queues created by the RPCServer will reduce. This can have a very good impact on large-scale scenario using RabbitMQ message broker.

アップグレード時の注意

  • The WSGI script neutron-api has been removed. Deployment tooling should instead reference the Python module path for this service, neutron.wsgi.api, if their chosen WSGI server supports this (gunicorn, uWSGI) or implement a .wsgi script themselves if not (mod_wsgi).

廃止予定の機能

  • Usage of tenant_id in the API policy rules is deprecated and will be removed in the 2027.1 release. Please use project_id instead.

バグ修正

  • Use of DHCPv6 option 59 (bootfile-name) is now supported with OVN. See bug: 2125715.

  • When OVS agent is restarting, it is now correctly restoring the tunnel outputs openflow rules so tunnels are still working correctly between computes. See bug 1978088 for details.

その他の注意点

  • It is assumed now that OVN supports external ports. This functionality was added in OVN v20.03.0.
