安装guest：
yum install gcc gcc-c++ vim wget lrzsz ntpdate sysstat dstat wget man unzip -y #安装常用包
mkdir /data
cd /data/ 用xshell的Xftp把iso上传过来（大于4G用Xftp，小于4G可以用lrzsz）
mount -o loop -t iso9660 /data/CentOS-6.5-x86_64-bin-DVD1.iso /mnt
配置网卡：
cp /etc/sysconfig/network-scripts/ifcfg-p3p1 /etc/sysconfig/network-scripts/ifcfg-br0

下一步开启vnc
"Start VNC"
，（其实字符界面也可以，至少速度快）步骤可以参考我博客KVM里面系统安装的操作

这里一步步 安装后，重启的时候会关机（因为配置文件 on_reboot = "destroy"）
现在修改配置文件
