開発中バージョンのリリースノート¶
27.0.0-54¶
新機能¶
Add the extension
extraroute-atomicto the ML2/OVN router plugin. This extension does not require any specific implementation.
Removed support for OVN versions under v20.03.0. The "ha_chassis_group" field is expected in the "Logical_Router_Port" Northbound table. For more information, see commit ovn: Support a new Logical_Switch_Port.type - 'external'.
The new
router-enable-snatextension API definition has been added. This extension makes public the router "enable_snat" boolean field. This field can be set during the router creation or updated when adding/updating the router gateways. Although the API allows to define a different value per gateway port (a router can have multiple gateways), only the first one will apply (this is a router level configuration flag).
An new option name
trunk_enabledhas been added toneutron-openvswitch-agentunderOVSgroup. This new option can be set toFalsein order to disable loading thetrunkextension on agent side. The default value for this option isTrueto keep backward compatibility with previous deployments. The recommendation is to set this option toFalseif you do not use thetrunkextension, 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-apihas 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.wsgiscript themselves if not (mod_wsgi).
廃止予定の機能¶
Usage of
tenant_idin the API policy rules is deprecated and will be removed in the 2027.1 release. Please useproject_idinstead.
バグ修正¶
The configuration parameters
ovn_dhcp4_global_optionsandovn_dhcp6_global_optionsallow multiple values per key, separated by a semi-colon character. E.g.: ntp_server:1.2.3.4,wpad:1.2.3.5;1.2.3.6
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.
