5     bjape01-ngx1                   running

8     bjape01-ngx2                   running

9     bjape01-ngx3                   running

13    bjape01-app-b1                 running

22    bjape01-con-b24                running

74    bjape01-core-b1                running

88    bjape01-wgw-b1                 running

89    bjape01-biz-b1                 running

91    bjape01-apache                 running

-     bjape01-ac-b1                  关闭

-     test                           关闭

2.关闭虚拟机

[root@bjape01-kvm1 ~]# virsh  shutdown bjape01-apache

域 bjape01-apache 被关闭

3.导出xml文件

cd /etc/libvirt/qemu

virsh dumpxml bjape01-apache.xml > bjape01-glb-a1.xml

4.编辑bjape01-glb-a1.xml文件

vi bjape01-glb-a1.xml

将bjape01-apache修改为bjape01-glb-a1

###name  虚机名字

###img    虚机磁盘文件

5.重定义

[root@bjape01-kvm1 qemu]# virsh undefine bjape01-apache

域 bjape01-apache 已经被取消定义

###取消原虚机的定义

[root@bjape01-kvm1 qemu]# virsh define bjape01-glb-a1.xml

定义域 bjape01-glb-a1（从 bjape01-glb-a1.xml）

###重新定义虚机

[root@bjape01-kvm1 qemu]# virsh list --all
