问题分析

在linux下的虚拟机出现了这个问题，问题的产生是因为之间做过部分的修改，clone等操作。 克隆之后的MAC地址也是之前的，所以说要修改成自动获取的MAC地址。

1.修改Centos虚拟机克隆机的HWADDR为ifconfig -a的MAC地址 
形如：HWADDR="00:0C:29:90:A7:23" 
2.然后再做以下操作 
[root@c1node01 ~]# rm -rf /etc/udev/rules.d/70-persistent-net.rules 
[root@c1node01 ~]# reboot 
……………… 
[root@c1node01 ~]# service network restart
