如果实例保持在中间状态，如 deleting，您可以使用 nova reset-state 命令来手动重置实例的状态为 error 状态。然后您就可以将实例删除。例如：
$ nova reset-state c6bbbf26-b40a-47e7-8d5c-eb17bf65c485
$ nova delete c6bbbf26-b40a-47e7-8d5c-eb17bf65c485
您也可以使用 --active 参数来强制实例回到 active 状态而不是 error 状态。例如：
$ nova reset-state --active c6bbbf26-b40a-47e7-8d5c-eb17bf65c485

3.增加一个未使用的IP

#把增加的IP分配给虚拟机（或者给新虚拟机分配该IP）：在面板操作为连接IP或新建虚拟机并选择此IP。
#允许新IP通过该虚拟机（openstack每个端口默认只允许一个Ip的数据报文通过）。
1.查看该虚拟机原来的IP的网卡所在的端口ID

2.修改该端口，允许通过IP（面板操作为：添加可用地址对）
