RDO Packstack 安装 Openstack Icehouse CentOS 6.5 单网卡
http://jasonyu37.blog.51cto.com/8877469/1421176CentOS 6.5 使用Redhat RDO packstack 安装openstack Icehouse
上一篇实际是有点问题的，就是没有办法访问vm，哈哈。
基本配置： vmware workstation 安装CentOS6.5，单网卡（eth1），桥接到笔记本的无线网卡上，
参考了陈沙克的文章：http://www.chenshake.com/centos6-4-single-card-all-in-one-install-havana/
就是把br-ex 桥接到 eth1 上，然后就可以设置笔记本用的无线网络的floating IP给vm使用，这样就可以访问VM了。

登录到dashboard.
1, 添加外部网络（就是我的无线网络） External_Network
添加 External_Subnet 192.168.1.0/24
2, 添加私有网络（就是VM所使用的网络） Private_Network
添加Private_Subnet 172.16.1.0/24
3, 添加路由器，router, 设置网关gateway为外部网络External_Subnet.
在路由器router上, 添加 172.16.1.0/24 网络的接口
4, 启动实例, 选择 Private_Subnet.
5，设置 floating IP. (192.168.1.131)
6，设置安全规则，允许icmp和ssh对内部网络的访问.
打完收工。
