克隆了一台Linux 虚拟机，在vbox中充值了网卡的MAC地址，启动OS后网络无法连接。http://www.cndba.cn/dave/article/3548

修改了网络配置文件中的HWADDR 和 rules中的配置信息：http://www.cndba.cn/dave/article/3548http://www.cndba.cn/dave/article/3548

[dave@www.cndba.cn network-scripts]# cat ifcfg-eth0

BOOTPROTO=none
HWADDR=08:00:27:a5:28:1b

[dave@www.cndba.cn network-scripts]# cat ifcfg-eth1
DEVICE=eth1

但重启网络后还是报错：

使用ifconfig -a 查看后发现网卡的名称并没有修改过来，还是之前的旧名称：

这里实际上之前rule 规则没有生效，可以通过重启操作系统或者重启UDEV来解决：http://www.cndba.cn/dave/article/3548http://www.cndba.cn/dave/article/3548http://www.cndba.cn/dave/article/3548

重启UDEV后，在重启网络恢复正常：

人的一生应该是这样度过的：当他回首往事的时候，他不会因为虚度年华而悔恨，也不会因为碌碌无为而羞耻；这样，在临死的时候，他就能够说：“我的整个生命和全部精力，都已经献给世界上最壮丽的事业....."
