virtualbox复制centos虚拟机

Bringing up interface eth0:  Device eth0 does not seem to be present,delaying initialization.

3.解决方案

a.删除/etc/udev/rules.d/70-persistent-net.rules中eth0整行，看哪一行的mac地址和virtualbox（网络的高级选项中可以看见）分配的一样，就把那一行的eth* 改为eth0

b.运行start_udev

c.注释/etc/sysconfig/network-scripts/ifcfg-eth0文件HWADDR信息

d.重启network服务
