本文主要是介绍Bringing up interface eth0: Error: No suitable device found: no device found for connection ‘System，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

解决Bringing up interface eth0: Error: No suitable device found: no device found for connection 'System eth0’报错

#service network restart
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:  Error: No suitable device found: no device found for connection ‘ System eth0′.[FAILED]

报错原因：在克隆虚拟机时连同它的物理地址也克隆了，当在一台新的虚拟机中打开时与原本虚拟机的物理地址冲突

解决方法

1、打开虚拟机设置→网络适配器→高级并且复制物理地址
在这里插入图片描述

2、替换虚拟机ifcfg-eth0网卡中HWADDR(即MAC)地址
在这里插入图片描述
3、保存并且退出重启网卡→成功

# service network restart
