删除一个实例：

   +--------------------------------------+----------------------+--------+------------+-------------+------------------+
   | ID                                   | Name                 | Status | Task State | Power State | Networks         |
   +--------------------------------------+----------------------+--------+------------+-------------+------------------+
   | 84c6e57d-a6b1-44b6-81eb-fcb36afd31b5 | myCirrosServer       | ACTIVE | None       | Running     | private=10.0.0.3 |
   | 8a99547e-7385-4ad1-ae50-4ecfaaad5f42 | myInstanceFromVolume | ACTIVE | None       | Running     | private=10.0.0.4 |
   | d7efd3e4-d375-46d1-9d57-372b6e4bdb7f | newServer            | ERROR  | None       | NOSTATE     |                  |

2. Use the following command to delete the newServer instance, which is in ERROR state:

   当实例的状态为ERROR时，使用下面的指令删除指定的服务器实例：

   $ nova delete newServer

   $ nova list

   +--------------------------------------+----------------------+--------+------------+-------------+------------------+
   | ID                                   | Name                 | Status | Task State | Power State | Networks         |

   | 8a99547e-7385-4ad1-ae50-4ecfaaad5f42 | myInstanceFromVolume | ACTIVE | None       | Running     | private=10.0.0.4 |
   +--------------------------------------+----------------------+--------+------------+-------------+------------------+ 

   The deleted instance does not appear in the list.
