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

#增加一个IP（非dhcp段）
1.查找子网段ID
neutron subnet-list
2.查找网络段ID
neutron net-list
3.增加一个未使用的IP
neutron port-create --fixed-ip subnet_id=1817a471-e8a3-4029-8468-1a1a6cb1bf86【子网段ID】,ip_address=192.168.200.232 c5bc18ea-cfda-4e76-adb8-0d38d1b7663d【网络段ID】
#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
neutron port-list | grep '192.168.200.44'
2.修改该端口，允许通过IP（面板操作为：添加可用地址对）
neutron port-update c1a258f9-b75c-45b3-b772-6396f763b56b --allowed-address-pairs type=dict list=true ip_address=192.168.200.231
2.1.也可修改通过一个网段
neutron port-update 1effb238-d49b-4679-91b9-d843a8ff3e30 --allowed-address-pairs type=dict list=true ip_address=172.16.8.0/24
