本文详细介绍了如何解决在克隆CentOS虚拟机时遇到的网络设备不存在的问题，包括删除持久化网络规则、更新MAC地址和UUID、重启系统以及可能的设备名称调整步骤。

clone a centos vm, there is no ethX device. To fix the problem,following the steps

1.# rm -f /etc/udev/rules.d/70-persistent-net.rules
2.# vim /etc/sysconfig/networking/devices/ifcfg-ethx
//the obove file doesn't exist in my system
/etc/sysconfig/network-scripts/ifcfg-ethx
    update MAC and UUID //or delete them
3.#reboot
4.#service network restart

Note:there maybe another situation that the ifcf-eth1 is existed but the device
is eth0, so change ifcfg-eth1 ---> ifcfg-eth0, or othewise.
