克隆虚拟机之后更改ip报错Bringing up interface eth0: Error: No suitable device found: no device found for connection 'System eth0'.

Bringing up interface eth0:  Error: No suitable device found: no device found for connection 'System eth0'.

 

原因是由于 /etc/udev/rules.d/70-persistent-net.rules文件中的HWaddr和/etc/sysconfig/network-scripts/ifcfg-eth0的HWaddr与新机器的HWaddr不符

解决方法，删除/etc/udev/rules.d/70-persistent-net.rules之后重启机器，然后更改/etc/sysconfig/network-scripts/ifcfg-eth0的HWaddr与70-persistent-net.rules中的相等即可
