好了，下面就可以新建虚拟机了，只需要注意选择安装方式和内存分配合理就可以了。装好一个，可以克隆另一个。
不使用图形界面启动虚拟机方法一:# cd/etc/xen# vimtestKernel="/tmp/vmlinuz-2.6.18-308.el5xen" //虚拟机启动后/boot目录下的文件，需要虚拟机安装完成后去复制Ramdisk="/tmp/initrd-2.6.18-308.el5xen.img" //虚拟机启动后/boot目录下的文件，需要虚拟机安装完成后去复制Name="test"Memory=512Vcpus=2Root="/dev/vol0/rootro"Extra="rhgbquiet"Vif=['bridge=xenbr0']Disk=['file:/var/lib/libvirt/images/test.img,xvda,w']# xmcreate test# xm list# xm console test //查看启动过程，推出"ctrl+]"
方法二:# vimtest2Bootloader="/usr/bin/pygrub" //不需要用到引导内核，直接使用虚拟机自己的内核Name="test2"Memory=512Vcpus=2Vif=['bridge=xenbr0']Disk=['file:/var/lib/libvirt/images/test.img,xvda,w']On_reboot='restart'On_crash='destroy'Vfb=['vnc=1,vnclisten=0.0.0.0,vncpasswd=vpass'] #定义帧缓冲# xm create -c test2 //-c 立即链接到控制台
domu中按装运行Redhat 5，要使用images，/etc/xen目录下的专用内核,redhat5没有收录xen的模块 kvm虚拟化
Kvm只能在64位系统上运行一、检验cpu是否支持硬件虚拟化# grep -o -E 'svm|vmx'/proc/cpuinfoSvm AMD的cpuVmx intel的cpu二、加载两个模块
如果是intel的cpu# modprobe kvm# modprobe kvm_intel如果是amd的cpu# modprobe kvm# modprobe kvm_amd# lsmod | grep kvmkvm_intel 53484 0kvm 316506 1 kvm_intel# ls /dev | grep kvmkvm #虚拟的设备文件，kvm的api，对虚拟机的操作都要通过这个接口此时，说明系统已经可以虚拟化了。
kvm跟qemu结合起来才能更好地完成虚拟化# yum -y groupinstall“Virtualization”# yum groupinfo"Virtualization"Loaded plugins:fastestmirrorSetting up GroupProcessLoading mirrorspeeds from cached hostfile

qemu命令可以创建，启动，安装虚拟机# qemu -img 创建映像文件# service libvirtd start# ifconfigEth0LoVirbr0# yum -y installbridge-utils# virsh iface-bridge eth0 br0#ifconfigBr0Eth0LoVirbr0
遇到报错，cant find eth0 or br0 already exsit只了到错误不要急，解决办法如下：重新编写eth0网卡信息，将br0网卡备份，然后再执行命令virsh iface-bridge eth0 br0 问题解决。接下来装操作系统
错误问题解决：利用Xshell安装虚拟机的时候，很多按键都会错乱，这时，我们可以选择使用putty和Xming两个软件结合使用来完成安装。Putty+Xming=Xshell+XmanagerWindows上安装putty和Xming
