以映像文件方式保存的虚拟机复制非常方便. 只要拷贝xen vm的img镜像文件和配置文件，并修改相应配置文就可以了
1.关闭虚拟机 xm shutdown vm1
2.复制虚拟机映像文件和配置文件 \cp /opt/vm1/vm1.img /opt/vm1/vm2.img \cp /etc/xen/vm1 /etc/xen/vm2
3.修改虚拟机配置文件 vi /etc/xen/vm2
name = “vm1” uuid = “85386e79-9f79-e243-9b62-3c9da736ae9f” maxmem = 2048 memory = 2048 vcpus = 2 bootloader = “/usr/bin/pygrub” on_poweroff = “destroy” on_reboot = “restart” on_crash = “restart” disk = [ “tap:aio:/opt/vm1/vm1.img,xvda,w” ] vif = [ “mac=00:16:36:47:a2:89,bridge=virbr0,script=vif-bridge” ]修改name,uuid,mac保持唯一,通常将最后一位加1,修改disk路径. 修改后的配置
name = “vm2” uuid = “85386e79-9f79-e243-9b62-3c9da736ae0f” maxmem = 2048 memory = 2048 vcpus = 2 bootloader = “/usr/bin/pygrub” on_poweroff = “destroy” on_reboot = “restart” on_crash = “restart” disk = [ “tap:aio:/opt/vm1/vm2.img,xvda,w” ] vif = [ “mac=00:16:36:47:a2:80,bridge=virbr0,script=vif-bridge” ]4.启动并进入虚拟机 vm create vm2 -c
5.修改主机名 5.1 hostname vm2
5.2 vi /etc/sysconfig/network
5.3 vi /etc/hosts
6.修改网卡ip和mac,和xen配置对应 vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0 BOOTPROTO=static BROADCAST=192.168.122.255 HWADDR=00:16:36:47:A2:80 IPADDR=192.168.122.12 NETMASK=255.255.255.0 NETWORK=192.168.122.0 ONBOOT=yes7.重启网络,完成修改 /etc/init.d/network restart
8.测试 8.1 ctrl+]退出虚拟机 8.2启动”vm1″虚拟机 8.3测试vm1网络 ping 192.168.122.11 8.4测试vm2网络 ping 192.168.122.12 8.5测试虚拟机之间的网络 vm console vm2 ping 192.168.122.11
ps:随宿主启动及服务相关iptables不要忘记
用virt-clone 命令不是更方便一点嘛，只需要进到新的虚拟机中改个ip就行了
