又过了一年了，红帽已经发布了RHEV 3.0的正式版本，详细的可以看这个链接 https://www.redhat.com/apps/store/rhev/
先说一下我的环境吧，RHEL 6.2 （CentOS 6.2我也试过了，可以使用），配好YUM源，然后运行脚本，然后用ifconfig 把一块网卡的IP临时配置成固定的，最后用启动DHCP服务就可以了。
为了实验的方便，我是在VMWARE虚拟机中做的实验。
脚本是根据RHEVH光盘里面的脚本改写的，执行格式是
sh pxe.sh ISO镜像

脚本的主要内容：
#!/bin/bash
#author suzezhi
#based on RedHat livecd-iso-to-pxeboot script
