Centos下yum安装
Foobar2000 W
首先，vps要ovz或者xen
以下例子为centos 5.X 32/64系统，其它系统需要对应修改。
1.清理不必要的文件和关闭不必要的服务提升效率
yum -y remove httpd

yum clean all
2.安装Linux GUI图形界面(这里以GNOME为例，也可以装KDE等等)
yum -y groupremove "GNOME Desktop Environment"
yum -y update
yum clean all
3.安装VNCSERVER，让Linux可以远程连接图形界面
这里省略，详情参考 CentOS安装轻量级桌面Fluxbox+VNC
4.安装QEMU虚拟机(CentOS5.X以外的系统建议直接下载所需的rpm，再根据提示补完组件。)
#安装所需的组件
yum install libICE.so.6 libImlib.so.1 libORBit-2.so.0 libSM.so.6 libX11.so.6 libXext.so.6 libXft.so.2 libXinerama.so.1 libXrandr.so.2 libXrender.so.1 libart_lgpl_2.so.2 libatk-1.0.so.0 libbonobo-2.so.0 libbonobo-activation.so.4 libbonoboui-2.so.0 libcairo.so.2 libfontconfig.so.1 libfreetype.so.6 libgconf-2.so.4 libgdk-x11-2.0.so.0 libgdk_pixbuf-2.0.so.0 libgnome-2.so.0 libgnome-desktop-2.so.2 libgnome-keyring.so.0 libgnomecanvas-2.so.0 libgnomeui-2.so.0 libgnomevfs-2.so.0 libgtk-x11-2.0.so.0 libpango-1.0.so.0 libpangocairo-1.0.so.0 libpangoft2-1.0.so.0 libstartup-notification-1.so.0 libungif.so.4 gtk+ libgdk-1.2.so.0 libglib-1.2.so.0 libgmodule-1.2.so.0 libgtk-1.2.so.0 libSDL-1.2.so.0 libX11.so.6 libasound.so.2 libbluetooth.so.2 libesd.so.0 curl ncurses -y
#安装QEMU所需RPM包
wget http://pkgs.repoforge.org/qemu/qemu-0.14.1-2.el5.rfx.i386.rpm
wget http://pkgs.repoforge.org/qemu/qemu-img-0.14.1-2.el5.rfx.i386.rpm
wget http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/imlib-1.9.13-1.el5.rf.i386.rpm
rpm -i imlib-1.9.13-1.el5.rf.i386.rpm
rpm -i qemu-img-0.14.1-2.el5.rfx.i386.rpm
rpm -i qemu-0.14.1-2.el5.rfx.i386.rpm
5.创建虚拟机镜像文件
#2k3.img为镜像文件名称，10G为镜像文件大小
qemu-img create -f qcow 2k3.img 10G
6.启动VNC(已启动可以跳过此步)
vncserver
7.连接VNC
8.加载ISO文件到虚拟光驱并启动镜像
#system.iso为ISO文件名，2k3.img为虚拟机镜像文件
qemu -cdrom system.iso -m 512M -boot d 2k3.img
安装完成之后，就可以使用了。
这个是直接启动虚拟机的命令
#启动虚拟机，禁用usb，转发3389端口到宿主系统;389为主机端口，3389为虚拟机端口
qemu -hda 2k3.img -boot c -m 512M -k de -usb -redir tcp:389::3389
