Current Series Release Notes

21.0.0.0rc1-87

New Features

  • Introducing clean_devices, a new DHCP driver’s API that can be called to clean stale devices.

Upgrade Notes

  • The default value for the metadata_workers configuration option has changed to 0 for the ML2/OVN driver. Since [OVN] Allow to execute “MetadataProxyHandler” in a local thread, the OVN metadata proxy handler can be spawned in the same process of the OVN metadata agent, in a local thread. That reduces the number of OVN SB database connections to one.

Bug Fixes

  • 1996677 When the fixed_ips of metadata port is modified, the ip address of tap device in metadata agent is modified.

Other Notes

  • Since OVN 20.06, the “Chassis” register configuration is stored in the “other_config” field and replicated into “external_ids”. This replication is stopped in OVN 22.09. The ML2/OVN plugin tries to retrieve the “Chassis” configuration from the “other_config” field first; if this field does not exist (in OVN versions before 20.06), the plugin will use “external_ids” field instead. Neutron will be compatible with the different OVN versions (with and without “other_config” field).
