Автопилот OpenStack - не Может присоединить объем к экземпляру

Мне удалось развернуть OpenStack на 6 машинах с помощью Альбомного Автопилота. Я могу создать экземпляры (без объема) и другие вещи.

Это кажется работами хорошо, пока я не пытаюсь присоединить объем к экземпляру через клиент Горизонта или OpenStack CLI. Это всегда перестало работать. В Горизонте нет никаких сообщений об ошибках.

Подобная проблема происходит, когда я пытаюсь создать экземпляр с, 'Создают новый объем', включил (в Горизонте). В этом случае было сказанное сообщение об ошибке:

"Error: Failed to perform requested operation on instance "xxxxxx" the instance has an error status: Please try again later [Error: No valid host was found. There are not enough hosts available]"

Для получения дополнительной информации я использовал Ubuntu 16.04 LTS, версия 2.1.3 МААСА, версия 2.1.2 Амулета и колдование как инструменты для развертывания OpenStack.

Пожалуйста, помогите мне. Это был 1 месяц, с тех пор как мне удалось развернуть OpenStack, эта проблема не была решена вообще.

Обновленный
вот nova-compute.log (тот, который обнаружился, когда я пытался присоединить объем к экземпляру),
