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。
