The API reference [1] certainly seems to indicate that there should be a /v2.1/ endpoint for Nova (e.g. it lists "/v2.1/​{tenant_id}​/servers") but my recollection was that we were trying to avoid this so that you would instead continue to use a /v2/ endpoint and the nova API server would determine which version the client supported based on whether or not it exposed a X-OpenStack-Nova-API-Version header, and if it did then by evaluating the version specified [2].

Have you tried just calling / on the /v2/ endpoint and seeing what it returns [3] - I'd expect it will say that the endpoint currently supports v2.1 without any new endpoint being required (basically the contents of nova version-list).
