用命令测试安装好的OpenStack环境
OpenStack三个节点icehouse-gre模式部署一文部署了一套OpenStack环境，接下来使用命令测试一遍。首先要明确几个概念：
外网：可分配floating ip绑定到虚拟机，外部就可以访问虚拟机。
虚拟网络（内部网络，私有网络）：虚拟机的虚拟网卡所在的私有网络。
子网：用户创建的每个网络至少要有一个子网（也可以有多个子网）
路由：用户创建的每个网络至少有一个路由，该路由的接口要关联这个网络
fixed ip:虚拟机网卡在虚拟网络上的ip
floating ip:虚拟网络对应的外部网络上的ip
interface:一个网络接口
端口：子网有多个端口（一般会有MAC地址和IP地址），在GRE模式中子网中一般会有qdhcp端口，qrouter端口和为虚拟机实例分配的端口，它们的ip地址属于这个子网

四、安全组规则
安全组规则会影响到外面ping虚拟机和ssh登录虚拟机，所以在controller节点中为openstack设置好ICMP和TCP规则。
这里设置安全组规则相当于打开防火墙端口，允许ssh和ping虚拟机，这是个重点，不设置这个将无法访问虚拟机。
获得TenantA的default安全组规则
# neutron --os-tenant-name TenantA --os-username UserA --os-password password --os-auth-url=http://localhost:5000/v2.0 security-group-list
root@controller:~# neutron --os-tenant-name TenantA --os-username UserA --os-password password --os-auth-url=http://localhost:5000/v2.0 security-group-list
