二、修改内核为xen的内核，重启
　　cat /proc/cpuinfo |grep flags
　　amd的cpu，如果有svm，或者intel的cpu 如果有vmx则可以开启完全虚拟化，即hvm的选项
　　三、安装centos
　　网络安装
　　virt-install --paravirt --name tapas_os --ram=3072 --file=/opt/xen/dianxin.img --file-size=40 --nographics --location http://centos.scalethink.com/centos/5.5/os/x86_64/
　　四、安装ubuntu
　　镜像安装，只能使用hvm
　　virt-install --hvm --name tapasos127 --ram=3072 --os-type=linux --file=/opt/xen/tapas.img --file-size=40 --vnc -c /opt/ubuntu-10.04.1-alternate-amd64.iso
　　安装后需要在别的机器上装virt-manager连这宿主机来监控安装
　　网络安装
　　virt-install --paravirt --name tapas_os --ram=3072 --file=/opt/xen/dianxin.img --file-size=40 --nographics --location http://mirrors.163.com/ubuntu/dists/natty/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/
　　ubuntu这个路径太恶心了。。。
