说明：eth0,eth0:6 的HWaddr地址是一样，跟vif0.0不能一样，如果一样就是有问题了。
      上述结果已说明存在问题，HWaddr地址都一样，MAC地址重复，所以才会出现满屏的错误。

#手动指定一个一个MAC地址
vi /etc/ sysconfig/network-scripts/ifcfg-eth0
#重启网卡
service network restart
or
/etc/init.d/networt  restart

这种只是对当前会话有效，如果要设置成永久，最好设置开机启动：
在 /etc/rc.d/rc.local 中加入以下三行(也可在/etc/init.d/network中添加)
ifconfig eth0 down
ifconfig eth0 hw ether 01:20:0A:10:FD:FF
ifconfig eht0 up
