在CentOS 6.5 上 使用redhat RDO packstack安装 openstack icehouse
之前自己按照指南上装了好几次都出错了，后来发现了redhat RDO packstack 方式，安装成功了。http://openstack.redhat.com/Quickstart
Please name the host with a fully qualified domain name rather than a short-form nameto avoid DNS issues with Packstack.
# vi/etc/hosts
# 127.0.0.1
#
127.0.0.1 hostname
sudo yum update -ysudo yum install -y http://rdo.fedorapeople.org/rdo-release.rpm reboot.
sudo yum install -y openstack-packstackpackstack --allinone installation successful

登录，
已经有了一个public network （172.24.4.224/28），这个网络是连在主机的br-ex上的，
添加一个private网络（172.16.0.1/24），这个是给VM使用的，

然后添加一个路由器，网关设置为public network 172.24.4.228

然后给这个路由器添加Private网络的接口，172.16.0.1

然后在镜像那里启动实例，网络选择private_subnet, 下载私钥。
在网络拓扑那里显示就是这样的：
public - 172.24.4.228 - router10 - private 172.16.0.1 - vm 172.16.0.3
