两步：第一步导出XML：[root@ok ~]# virsh dumpxml centos02 >12c.xml第二步磁盘文件[root@ok virhost]# cp centos02.img 12c.img看看两个文件的不同：[root@ok ~]# diff /etc/libvirt/qemu/centos02.xml ~/12c.xml 1,10c1,3< 
     < < 
     
      <   
      
       centos02

[root@ok ~]# virsh define 12c.xml Domain 12c defined from 12c.xmlroot@ok ~]# virsh start 12cDomain 12c started[root@ok ~]# virsh list Id    Name                           State---------------------------------------------------- 1     win7                           running 2     centos02                       running 3     12c                            running

 可以把/etc/sysconfig/network-script/ifcfg-eth0里面的MAC UUID都可以删除了

#pwd#/etc/udev/rules.d#rm  -f 70-persistent-net.rules然后重启[root@ok virhost]# virsh list Id    Name                           State---------------------------------------------------- 1     win7                           running 2     centos02                       running 3     12c                            running
