################# Detail of CPU ############
软件信息：
OS: Centos-5.4 64位 DVD.iso { [CentOS.5.4.].CentOS-5.4-x86_64-bin-DVD.iso }
Xen版本：xen-4.0.1.tar.gz
下载地址： (xen-4.0.1.tar.gz)
编译内核版本：2.6.34.8
Xen-patch下载地址：
第一周任务具体步骤如下：
1. 首先安装系统，在安装过程中设置root密码cloudisgood 新建cloud用户，密码cloudisgood
网络方式选择DHCP,自动获取到222.24.10.0/24网段的IP地址…
硬盘分区情况如下：
250GB硬盘
200MB -à /boot
248GB à / (为了简单先可以这样，等一切OK,就可以专门留出一个200GB分区存放虚拟机)
2GB à swap
安装过程中需要自定义安装哪些软件包..有些是必须的，有些则可以去掉，以节省硬盘空间；
以下软件包选择原则：
桌面环境选择->gnome 桌面环境
应用程序选择-> 图形，图形化互联网，编辑器
开发 -> 开发库，开发工具，Ruby
服务器-> 网络服务器
基本系统-> X窗口系统，基本，管理工具，系统工具
虚拟化->不选
集群-> 集群
集群存储->集群存储
语言->中文支持
2. 安装完系统以后就可以先使用系统自带的内核2.6.18-(164|195|***)进入系统，把准备好的xen-4.0.1.tar.gz和linux-2.6.34.8.tar.bz2的内核源码包，还有xen-patch-2.6.34.tar.gz的内核xen补丁包也一起放在/usr/src/目录下
3. 下面就使用命令来说明
tar xvf linux-2.6.34.8.tar.bz2
tar xvf xen-4.0.1.tar.gz
mkdir patch
tar xvf xen-patch-2.6.34.tar.gz –C ./patch
ln –s linux-2.6.34.8 linux
cd linux
make clean
make mrproper
接下来用一个小脚本将xen内核补丁打上，如下：
for i in `ls ../patch/*
do
patch –p1 < ../patch/$i
done
然后可以使用find . –name *.rej看看有没有被reject没打上的补丁，有时候会有。
现在需要一个.config文件,直接使用我已经配置好的拷贝过来，放在此目录下/usr/src/linux/.config
然后还需要make menuconfig看看内核配置选项的一些情况，有可能需要再调整一些，在这里配置这个内核选项是详单花费时间和精力的，大部分默认即可，有些很清楚的可以自己调整。
make menuconfig如下图：
配置xen相关信息：
配置完以后可以看看相关的XEN的配置信息，如下图：
配置基本可以OK了，但是需要修改一点点代码才能一直顺畅的编完整个过程，修改代码如下:
a) ./arch/x86/kernel/cpu/cpu.h 中36行需要改成如下
b) vim arch/x86/kernel/cpu/common-xen.c 将其中576-615行对get_cpu_cap函数的实现放在 vim arch/x86/kernel/cpu/intel.c 的前面,如下效果：
其实也就是说，必须在intel.c代码中队get_cpu_cap函数的具体实现进行定义,否则会出现错误终端编译过程;
到了这一步基本就可以开始make了，但是为了加快速度，可以让他多线程的跑着;
make –j4 四线程
make –j2 双线程
在编译过程中最好的就是什么问题都不要出现，内核编完就可以
make –j4 (-j2) modules编译模块了
两部都没有问题就可以make modules_install安装模块，再接着make install安装内核了（这一步必须得先安装模块，在暗转内核，我碰到了这个问题）
4. 编完了内核就可以开始编译xen了，当然也可以先编译xen,在编译内核，都是可以的，我们选择了先编译xen。在编译xen的过程中会遇到一些包依赖的问题，有些可以yum安装，有些需要源码安装，有些也可以rpm包安装。
所以最好在编译xen之前就先解决这些依赖关系:
以下是xen源码包里面README.txt里面提出的requirements,除此之外还有一些需求，可以在以后继续补充。
编译xen的命令如下：
make xen
make tools
make stubdom (在编译这个的过程中会需要联互联网，所以必须在这之前保证网络通畅)
安装时需要注意make install-tools 后面的参数
make install- xen
make install-tools PYTHON_PREFIX_ARG=
make install- stubdom
如果没有问题，那么就算把xen安装完了。
5. 现在把xen和内核都安装好了，再修改一下grub.conf配置文件，添加如下信息即可：
