Vitrualbox Copy the CentOS system network card settings

1. Make sure that the copied system is in a closed state and not in hibernation, or that there is only one eth0 in the/etc/udev/rules.d/70-persistent-net.rules file under the new system that is being copied. The eth0 and eth1 two NICs are duplicated in the off state.

2. After the copy is complete, vi enters the/etc/udev/rules.d/70-persistent-net.rules

At this point, you can see two ETH

Delete the eth0, the contents of the following eth1 eth1 instead of Eth0,wq save to exit, reboot restart.
