Windows2008r2系统中hyper-v虚拟机安装CentOS

1、在Hyper-V控制台新建虚机，注意虚机的网卡先选择“旧版网络适配器”，主要是方便有关服务的网络在线安装。

2、到微软网站下载支持包，Linux Integration Services v2.1 for Windows Server 2008 Hyper-V R2
http://www.microsoft.com/downloads/zh-cn/details.aspx?displaylang=zh-cn&FamilyID=eee39325-898b-4522-9b4c-f4b5b9b64551
解压得到LinuxIC v21.iso文件

3、以最小化方式安装Centos，除了必要的组件，其它不安装。

4、Centos安装完成后根据自己的网络环境配置网络，配置好后要能顺利的访问外网资源
（1）配置IP
vi  /etc/sysconfig/network-script/ifcfg-eth0
根据自己的环境来配置IP和子网掩码
（2）配置网关
在ifcfg-eth0添如如下命令
GATEWAY=你的网关地址
（3）配置DNS
编辑/etc/resolv.conf文件，添如如下命令
nameserver  你的DNS服务器地址
（4）重启网络服务，测试外网的访问。
service network restart

5、网络安装以下组件命令如下：
yum  install  make  kernel-devel  gcc  perl  ?y

6、加载Hyper-v支持文件

7、把光盘的文件复制到硬盘进行编译，我的环境如下
mount /dev/cdrom /mnt
mkdir /root/hyper-v
cp ?R  /mnt/*  /root/hyper-v
cd  /root/hyper-v
rm /lib/modules/2.6.18-164.el5/build
ln ?s /usr/src/kernels/2.6.18-128.1.16.el5-x86_64/ /lib/modules/2.6.18-128.el5/build
make
make install
reboot

8、安装成功后把“旧版网络适配器”删除，添加新的“网络适配器”在Centos下重新配置网络环境，以达到最佳性能。
Hyper-V 虚拟机的 Linux 集成服务 v2.1 新特性有
Driver support for synthetic devices: Linux Integration Services supports the synthetic network controller and the synthetic storage controller that were developed specifically for Hyper-V.
Fastpath Boot Support for Hyper-V（Fastpath 引导支持）: Boot devices take advantage of the block Virtualization Service Client (VSC) to provide enhanced performance.
Timesync（时间同步）: The clock inside the virtual machine will remain synchronized with the clock on the host.
Integrated Shutdown（集成关机）: Virtual machines running Linux can be gracefully shut down from either Hyper-V Manager or System Center Virtual Machine Manager.
Symmetric Multi-Processing (SMP) Support（对称多线程处理支持）: Supported Linux distributions can use up to 4 virtual processors (VP) per virtual machine.
Heartbeat（运行状态）: Allows the host to detect whether the guest is running and responsive.
Pluggable Time Source（可插入的时钟源）: A pluggable clock source module is included to provide a more accurate time source to the guest.
