Xen 安装指南
+-----------------------------------------------------------------------------------------------------------------------+
|Xen windows installation precondition is: CPU must support virutalization technology, |
| AMD: more /proc/cpuinfo | grep pae |
| |
|Detail installation steps:
| 1. Install kernel package for Xen:
| yum -y install xen*
| yum -y install kernel-xen*
| Goto /boot/grub/grub.conf
| default=1 => default=0
| Make sure Xen kernel is the first one
此处可以重新启动机器使用ifconfig 来列出所有的网卡来验证虚拟网卡的安装是否成功。如果需要加多个虚拟网卡，可在此操作，具体步骤请参见：给 Xen 虚拟机添加一个网络接口
|2. Install vnc-server module:
| -> yum -y install vnc-server*
| -> As root:
| # useradd vncuser
| # passwd vncuser
| -> Login to each user(IMPORTANT), and run vncpasswd. This will create a .vnc directory.
| -> Edit /etc/sysconfig/vncservers, and add the following to the end of the file.
| VNCSERVERS="1:vncuser"
| VNCSERVERARGS[1]="-geometry 640x480"
| VNCSERVERARGS[1]="-geometry 800x600"
| ->start the VNC service by following command line:
| service vncserver start

| 3. Install Xen GUI management tool(can be used to generated the vm config):
| yum -y install virt-manager
| 4. Shutdown iptables service temporary to avoid the ip block for VNCServer, after installation done, we can resume it. |
| 5. In the GUI configuration, generate the necessary configuration file and then start the windows installation process.|
| 安装过程中如果停止在如下画面或者不断重启：
| 画面主要停止在starting windows...的蓝色界面上
| 此种问题一般是由于ACPI的问题，请在引导光盘启动后提示按F2或者F6的时候按下F7，禁用ACPI
