1、virsh dumpxml win7 | grep mac   #查看win7虚拟机mac

2、arp -a   #显示mac与ip对应关系

示例：

[root@localhost ~]# virsh dumpxml ubuntu-yusen | grep mac
    <partition>/machine</partition>
    <type arch='x86_64' machine='pc-i440fx-rhel7.0.0'>hvm</type>
      <mac address='52:54:00:11:c5:4e'/>
[root@localhost ~]# ping 192.168.0.19

? (192.168.0.19) at 52:54:00:11:c5:4e [ether] on br0
[root@localhost ~]#

说明：

1、ubuntu-yusen是虚拟机名称；

2、arp -a | grep 52:54:00:11:c5:4e 是找mac对应的ip。
