Looks like we use API_MAX_VERSION and DEFAULT_OS_COMPUTE_API_VERSION with wrong way. This isn't broken with rackspace only, this broken novaclient runing with nova legacy v2 api(legacy v2 api's behavior is no version exposed).
API_MAX_VERSION is the max version of client supported, currently it should be '2.5' DEFAULT_OS_COMPUTE_API_VERSION is the default value of CLI option of '--os-compute-api-version', ti should be '2.latest' which means let CLI to negotiate with server side choice most recently version. Not sure whether we need revert, but at least a new fix should come after that.
