экземпляр не работает из-за ошибки подключения взгляда

Я настраиваю пример архитектуры из http://docs.openstack.org/newton/install-guide-rdo/

Я в главе Запустить экземпляр

Когда я запускаю экземпляр, я получаю следующее сообщение об ошибке, отображаемое в информации об экземпляре:

Build of instance bcaa06fe-99ca-4db7-baf3-633f21b16f61 aborted: Connection to glance host http://controller:9292 failed: Error finding address for http://controller:9292/v2/images/41dc78dd-963d-4a84-a872-35d1d3cb3f7c/file: HTTPConnectionPool(host='control

Когда я просматриваю журналы своего вычислительного узла в /var/log/nova/nova-compute.log, я замечаю следующие два сообщения об ошибках:

• ConnectFailure: невозможно установить соединение с http://127.0.0.1:9696/v2.0/networks.json?id=b4fb8e4a-cbbc-43e8-9e80-4abede8e4d56
• CommunicationError: Ошибка при поиске адреса для http: // контроллер: 9292 / v2 / images / 41dc78dd-963d-4a84-a872-35d1d3cb3f7c / file:

Как отладить и решить эту проблему?
