本文记录了OpenStack环境中Nova服务出现自动禁用的问题及解决过程。控制节点显示Nova服务因连续10次构建失败而被禁用，在确认计算节点服务仍运行后，通过命令重新启用服务。

### 一开始还是可以创建的，突然出现这个问题

###在控制节点查询nova 的服务状态是不可用的，提示

openstack nova disabled  Auto-disabled due to 10 build failures

### 状态时 disabled 但是查看该计算节点的服务状态是Running 的

###查看nova 的命令

[root@controller12 nova]# nova  service-enable 883ed54e-8837-4d12-b201-c3c9127918d2

+--------------------------------------+-----------+--------------+---------+
| ID                                   | Host      | Binary       | Status  |
+--------------------------------------+-----------+--------------+---------+
| 883ed54e-8837-4d12-b201-c3c9127918d2 | compute14 | nova-compute | enabled |
+--------------------------------------+-----------+--------------+---------+

### 再次查看服务enable

[root@controller12 nova]# nova service-list
