问题导读

1.如何使用neutron命令？
2.如何查看具体某个命令的参数解释？
3.如何查看ovs创建网桥

创建实例失败：
首先用下面命令查看服务是否正常

nova-manage service list
复制代码

如果不正常，则使用下面命令重启，如果还不行，则查看日志，

service nova-api restart
service nova-cert restart
service nova-consoleauth restart
service nova-scheduler restart
service nova-conductor restart
service nova-novncproxy restart
复制代码

对网络的判断：

可以查看网桥

 ovs-vsctl show
复制代码

如果不会使用ovs，则可以使用

 ovs-vsctl  --help
复制代码

如果看不懂，则查看openstack Juno neutron必读系列文章：

网络流量查看：

udhcpc eth0
复制代码

neutron命令的使用

neutron --help
复制代码

关键这些命令该如何使用：
例如我们想查看网络

neutron net-list
复制代码

如果我们查看某个特定的信息，则使用show命令
比如我们想查看上述网络的 demo-net具体信息。其他的依次类推

neutron net-show  demo-net
复制代码

而有些比较复杂，比如我们想删除路由的某个端口，
我们不知道后面跟什么参数，只看到了命令，该如何处理

 router-interface-delete
复制代码

使用下面命令

neutron  router-interface-delete --help
复制代码

列出下面参数：
也就是需要一个路由的id，以及SUBNET|subnet=SUBNET|port=PORT这些参数都是可以的

usage: neutron router-interface-delete [-h] [--request-format {json,xml}]
                                       router-id INTERFACE

Remove an internal network interface from a router.

positional arguments:
  router-id             ID of the router.
  INTERFACE             The format is "SUBNET|subnet=SUBNET|port=PORT". Either
                        a subnet or port must be specified. Both ID and name
                        are accepted as SUBNET or PORT. Note that "subnet="
                        can be omitted when specifying a subnet.

optional arguments:
  -h, --help            show this help message and exit
  --request-format {json,xml}
                        The XML or JSON request format.
