OpenStack neutron删除网络设备出错解决办法
目标：要删除外网Ext-Net2
直接删网络也会出错：因为有一个或多个端口在使用该网络

直接删port会出错，因为端口有浮点IP所以不能直接删除

通过horizon查看，发现该浮动IP，没有被分配，但是用命令却查不到
root@controller:~# nova --os-tenant-name TenantA --os-username UserA --os-password password --os-auth-url=http://localhost:5000/v2.0 floating-ip-list ERROR: The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-294eb77b-1615-46fb-93de-d10660a46b70)
没办法，只能手动从horizon释放掉浮动IP了。登录UserA，手动释放掉浮动IP10.100.0.3，现在就可以正常删除了。
现在删除Ext-Net2就没问题了。

总结：用admin删除网络时注意，admin看不到租户分配的浮动IP，所以得用租户登录释放掉浮动IP。
目标：删除租户的网络

路由接着外网和私网的子网。
所以先删路由上的网关
root@sc-ctrl01:~# neutron router-gateway-clear TenantB-Router Removed gateway from router TenantB-Router
再删路由上的接口，删除某个路由的某个接口
root@sc-ctrl01:~# neutron router-interface-delete TenantB-Router TenantB-Net-SubNet Removed interface from router TenantB-Router. root@sc-ctrl01:~#
port是关联路由和子网的。所以清掉路由上的接口，那port就没有了。
root@sc-ctrl01:~# neutron router-delete TenantB-Router Deleted router: TenantB-Router
接着删子网
root@sc-ctrl01:~# neutron subnet-delete TenantB-Net-SubNet Deleted subnet: TenantB-Net-SubNet
最后网络就可以删掉了
root@sc-ctrl01:~# neutron net-delete TenantB-Net Deleted network: TenantB-Net
