kvm虚拟化之kvm虚拟机克隆
kvm虚拟机的克隆分为两种情况，本文也就通过以下两种情况进行克隆，克隆虚拟机为OEL5.8X64。
(1) KVM主机本机虚拟机直接克隆。
(2) 通过复制配置文件与磁盘文件的虚拟机复制克隆(适用于异机的静态迁移)。
1. 本机虚拟机直接克隆
(1) 查看虚拟机配置文件
[root@node1 ~]# cat /etc/libvirt/qemu/oeltest01.xml <!--

OVERWRITTEN AND LOST. Changes to this xml configuration should be made using:
virsh edit oeltest01
or other application using the libvirt API.

虚拟机磁盘文件: /data/test01.img
虚拟机名称：oeltest01
(2) 开始克隆
# virt-clone -o oeltest01 -n oeltest02 -f /data/test02.img
说明：以oeltest01做为源，克隆oeltest01虚拟机，并创建名称为oeltest02虚拟机，使用磁盘文件/data/test02.img
(3) 启动虚拟机并配置主机名，IP地址等
[root@node1 data]# virsh console oeltest02

2. 复制配置文件与磁盘文件克隆
(1) 导入kvm虚拟机配置文件
这里采用oeltest01做为模板，进行克隆。
# virsh shutdown oeltest01
# virsh dumpxml oeltest01 > /etc/libvirt/qemu/oeltest03.xml
(2) 复制kvm虚拟机磁盘文件
本系列文章都是采用虚拟磁盘文件进行测试，没有使用lvm卷。
通过查看配置文件：虚拟磁盘位置<source file='/data/test01.img'/>
(3) 直接编辑修改配置文件
修改name,uuid,disk位置,vnc端口
此时还是将该配置文件注册进来，无法通过virsh edit进行编辑。
[root@node1 data]# vi /etc/libvirt/qemu/oeltest03.xml

(4) 定义新虚拟机配置文件
[root@node1 data]# virsh define /etc/libvirt/qemu/oeltest03.xml
启动虚拟机
[root@node1 data]# virsh start oeltest03
域 oeltest03 已开始
(5) 登录虚拟机进行主机名，IP等修改
[root@node1 data]# virsh console oeltest03
连接到域 oeltest03

本文到此通过两种方式进行kvm虚拟机克隆，其实各有用处。
再次说明：本文克隆的虚拟机是oel5.8,如果克隆的虚拟机是RHEL/CentOS/OEL6.x操作系统，还需要修改/etc/udev/rules.d/70-persistent-net.rules文件。
