之前自己按照指南上裝了好幾次都出錯了，後來發現了redhat RDO packstack 方式，安裝成功了。
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 -y
sudo yum install -y http://rdo.fedorapeople.org/rdo-release.rpm
reboot.
sudo yum install -y openstack-packstack
packstack --allinone
installation successful

登錄，
已經有了一個public network （172.24.4.224/28），這個網絡是連在主機的br-ex上的，
添加一個private網絡（172.16.0.1/24），這個是給VM使用的，
然後添加一個路由器，網關設置爲public network 172.24.4.228
然後給這個路由器添加Private網絡的接口，172.16.0.1
然後在鏡像那裏啓動實例，網絡選擇private_subnet, 下載私鑰。
在網絡拓撲那裏顯示就是這樣的：
public - 172.24.4.228 - router10 - private 172.16.0.1 - vm 172.16.0.3
打開console
Sudo vi /etc/resolv.conf 設置dns，ping baidu 通了。
