Openstack 启动一个实例(九)

创建一个提供者网络：

# 创建一个提供者网络：
openstack network create  --share --external --provider-physical-network linux36 --provider-network-type flat linux36

--external                           # 声明是一个外部网络
--provider-physical-network linux36  # 自定义的网络名, ```/etc/neutron/plugins/ml2/ml2_conf.ini``` 中，flat_networks = linux36定义.
--provider-network-type flat linux36 # flat 单一扁平网络(就是桥接).

[ ~]# source admin.sh 
   ~]# openstack network create  --share --external --provider-physical-network linux36 --provider-network-type flat linux36
