Querying API Versions (Native OpenStack API)


This interface is used to query all available Nova versions.

To support function extension, Nova APIs can be distinguished by version. There are two types of versions:

  • Major version: independent URL
  • Microversion: Used by the HTTP request header X-OpenStack-Nova-API-Version. Since microversion 2.27, the new microversion header OpenStack-API-Version has been supported.
