目前系统为REHL6，内核为2.6.32-71.el6.x86_64版本，安装之后需要在此平台上使用KVM。GCC和KVM安装是必需的步骤，如果已经自带，则不必另行手动操作。本次是为手动安装过程，简单记录一下：

一.GCC安装：

1.获取相关的依赖包：

-rwxr-xr-x. 1 root root  1612992 Feb 23 09:20 libstdc++-devel-4.4.4-13.el6.x86_64.rpm
2.按照顺序安装GCC：

rpm -ivh glibc-common-2.12-1.25.el6.x86_64.rpm                                                        
rpm -ivh kernel-headers-2.6.32-131.0.15.el6.x86_64.rpm                                                         
rpm -ivh libgcc-4.4.5-6.el6.x86_64.rpm                                                                          
rpm -ivh glibc-2.12-1.25.el6.x86_64.rpm                 
rpm -ivh libgomp-4.4.5-6.el6.x86_64.rpm                 
rpm -ivh nscd-2.12-1.25.el6.x86_64.rpm                  
rpm -ivh glibc-headers-2.12-1.25.el6.x86_64.rpm         
rpm -ivh glibc-devel-2.12-1.25.el6.x86_64.rpm           
rpm -ivh mpfr-2.4.1-6.el6.x86_64.rpm                    
rpm -ivh ppl-0.10.2-11.el6.x86_64.rpm                   
rpm -ivh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm            
rpm -ivh cpp-4.4.5-6.el6.x86_64.rpm                     
rpm -ivh gcc-4.4.5-6.el6.x86_64.rpm                     
rpm -ivh libstdc++-4.4.5-6.el6.x86_64.rpm               
rpm -ivh libstdc++-devel-4.4.5-6.el6.x86_64.rpm         
rpm -ivh gcc-c++-4.4.5-6.el6.x86_64.rpm   

3.安装GCC-G++顺序如下：

rpm -ivh libstdc++-4.4.5-6.el6.x86_64.rpm       
rpm -ivh libstdc++-devel-4.4.5-6.el6.x86_64.rpm 
rpm -ivh gcc-c++-4.4.5-6.el6.x86_64.rpm        

注：如果存在报错或者依赖，需要根据提示寻找相关包或者提示查找并安装，过不去的包可以尝试采用加参数 --nodeps形式安装。

二.KVM安装：

1.下载KVM内核包qemu-kvm-0.14.1.tar.gz，并传至目标机器：

http://www.linux-kvm.org/page/Downloads

2.解压 tar -xvf qemu-kvm-0.14.1.tar.gz

解压之后开始安装：

./configure --prefix=/usr/local

make
make install

完成之后检查命令：qemu-system-x86_64 --help，可以查到帮助信息即表明OK。

为了方便起见可以： alias kvm="qemu-system-x86_64"
并写入vi ~/.bashrc ，source ~/.bashrc

接下来上传镜像，就可以使用了。
