KVM gust 模板安装
主要用到 virsh 命令
本次以用模板安装 vm00002 ，安装路径/data1/domains/vm00002/
准备工作
根据之前用图形安装的vm00001为模板，这个虚拟机是标准的rhel5.3系统
获取正在运行的vm00001的模板文件vm00001.xml 和vm00001的系统盘root.img
#显示正在运行的虚拟机
[root@localhost vm000001]# virsh list
Id Name State
----------------------------------------------------
52 vm00001 running
1.导出vm00001的xml格式的模板 命名为vm00001.xml
[root@localhost ~]# virsh dumpxml vm00001 >vm00001.xml
[root@localhost ~]# ls
anaconda-ks.cfg install.log install.log.syslog vm00001.xml
2.把这个模板放到/data1/domains/vm00002/ ,并改名为vm00002.xml
[root@localhost ~]# mkdir /data1/domains/vm000002 -p
[root@localhost ~]# mv vm00001.xml /data1/domains/vm000002/vm00002.xml
3.把vm00001的系统盘复制到/data1/domains/vm00002/
[root@localhost ~]# cp /data1/domains/vm000001/root.img /data1/domains/vm000002/
[root@localhost ~]# ls /data1/domains/vm000002/
root.img vm00002.xml
4.修改vm00002.xml 4个参数：name 、uuid、source file、mac分别在 第2、3、24、45行，因为这4个参数与别的虚拟机不能冲突，保存。
[root@localhost ~]# vim /data1/domains/vm000002/vm00002.xml
1 <domain type='qemu' id='52'>
2 <name>vm00001</name> #修改name为vm00002
3 <uuid>1b77f768-d75b-60bc-0b4c-27b108cc1155</uuid>#修改uuid,在最后一位数5变成6即可

5.启动vm00002
[root@localhost ~]# cd /data1/domains/vm000002/
[root@localhost vm000002]# virsh create vm00002.xml
Domain vm00002 created from vm00002.xml
6.查看运行的虚拟机状态
[root@localhost vm000002]# virsh list
Id Name State
----------------------------------------------------
52 vm00001 running
53 vm00002 running
7.virt-manager图形查看
[root@localhost vm000002]# virt-manager
Xlib: extension "RANDR" missing on display "localhost:12.0".
双击vm00002，查看是否正在启动
启动完毕后，这个vm00002与vm00001除了那4个参数不一样，其他都是一样的
结束。
