1 vmware克隆虚拟机
2 修改mac和uuid
1 删除网络规则
# rm -f /etc/udev/rules.d/70-persistent-net.rules
2 注释掉HWADDR和UUID
vi /etc/sysconfig/network-scripts/ifcfg-eth0
#HWADDR=00:0C:29:D6:47:C4
#UUID=91cdd450-a791-42c4-8a45-ef676b8c5cb1
3 重启网卡
# service network restart
4 查看Mac
ifconfig -a 可以看到分配的mac是00:50:56:37:E1:BE
5 配置对应ip，重启网卡，即可上网。
vi /etc/sysconfig/network-scripts/ifcfg-eth0

#HWADDR=00:0C:29:D6:47:C4
