Решение проблемы

Проблема возникает в том случае, если запись resource provider не соответствует хосту - то есть она существует, но неверная. А новую ресурсную запись nova создать не может, т.к. она уже существует - Conflicting.. already exist. Чтобы исправить, необходимо сначала найти и удалить провайдер ресурса для данного хоста: 

# openstack resource provider list --name cmpt-c01z03-a4002
+--------------------------------------+-------------------+------------+
| uuid                                 | name              | generation |
+--------------------------------------+-------------------+------------+
| a7c08f67-a39c-4dba-a688-8b2f08b16a67 | cmpt-c01z03-a4002 |         19 |
+--------------------------------------+-------------------+------------+

Удаляем: 

openstack resource provider delete a7c08f67-a39c-4dba-a688-8b2f08b16a67
Создаем новый: 
systemctl restart nova-compute
Проверяем: 
# openstack resource provider list --name cmpt-c01z03-a4002
+--------------------------------------+-------------------+------------+
| uuid                                 | name              | generation |
+--------------------------------------+-------------------+------------+
| 5658771b-93e7-42f2-9646-e0e932a2ff40 | cmpt-c01z03-a4002 |          2 |
+--------------------------------------+-------------------+------------
После этих действий все заработало.
