Cloudstack安装配置脚本
安装cents 6.3 ，配置yum，ip地址 且可以连接互联网
注意事项：
配置完整的hostname，这个是重点，用hostname -f可以解析出来主机名
本文仅仅是一个脚本，更多详细配置安装请参看cloudstack专业人士，我同事写的文档，http://clovemfong.blog.51cto.com/3297559/1310505，属于高质量的文档，应该是目前国内最专业的cloudstack文档，足以出一本书了。话说我学习cloudstack，就是同事一点一滴教的，非常感谢。大家可以多去看看他写的博客，这里说一下，他以前写过书的，书名这里就不提了。
其实shell脚本也可以写的，但是为了方便写成saltstack的模块，还是转换成了python的
#python cloudstackInstall.py
#cat cloudstackInstall.py
#!/usr/bin/env python
#coding=utf8
#author：itnihao
#date：2013-11-28
#version：1.0
#mail: itnihao@qq.com
'''
功能说明:
系统环境为rhel[centos]6.3或者6.4，目前6.3运行正常，6.4未测试
脚本自动下载cloudstack-management
虚拟化采用kvm，需要你的CPU支持虚拟化kvm
cloudstack-management和kvm为同一台机器
