1. What is the problem The current Nova_APIGW does not support microversion function, the service controller uses a fixed API version number to initialize novaclient 2. What is the solution to the problem When the service controller receives an API request, it will get the microversion number from request headers , and use this to initialize novaclient. For how to get the microversion number, please refer to: https://specs.openstack.org/openstack/nova-specs/specs/kilo/implemented/api-microversions.html The microversion supported range is 2.1 to latest version 3. What the features need to be implemented to the Tricircle to realize the solution Nova_APIGW microversion support added Change-Id: Idf44c91100e5cb8ad0355164c9be991aa54a652b
