Verified Combinations

This section describes different combinations of OpenStack and Open vSwitch versions that are expected to work with with different OpenDaylight versions. Using combinations outside this list may work but have not been verified.

Note

A verified combination is defined as a combinations that is actively tested and maintained. OpenDaylight, OpenStack and Open vSwitch are very active and quickly adding new features that makes it difficult to verify all the different release combinations. Different combinations are likely to work but support will be limited.

The following table details the expected supported combinations.

Supported Version Matrix
OpenDaylight OpenStack Open vSwitch Sync Notes
Carbon Ocata 2.7   Combination drops when Pike releases
Carbon Pike 2.8 S  
Nitrogen Ocata 2.7   Combination drops when Pike releases
Nitrogen Pike 2.9 S  
Oxygen Pike 2.8   Combination drops when Queens releases
Oxygen Queens 2.9 S  
Fluorine Queens 2.9   Combination drops when Rocky releases
Fluorine Rocky 2.11 S  
Neon Rocky 2.11   Combination drops when Stein releases
Neon Stein 2.11 S  
  • (S): in the Sync column indicates the final supported combination for that OpenDaylight release.
  • Differing release schedules will lead to short-lived combinations that will drop as the releases line up. An example is with Carbon that releases before Pike so for a period of time Carbon is supported with Ocata.
  • The current OpenDaylight version and the previous will be supported. Boron support will drop when Nitrogen releases; Carbon support will drop when Oxygen releases.
