The network card cannot be started after the VMware virtual machine clones the CentOS operating system

First, the simulation environment:

VMware virtual Machines

CentOS Source Operating System

Cloning the CentOS operating system

Second, the problem: After the VM cloning the operating system, the network card does not function

Third, the solution / steps:

#vim/etc/udev/rules.d/70-persistent-net.rules

Delete the original eth0 command line and change the name of the new eth1 command line to Eth0

#shutdown – R Now

That is, after the operating system restarts, the network card runs normally.

Description: Why cloning? I think there are several aspects of the meaning:

1. Equivalent to good backup system, the source system is out of the question, the clone system can be put into use immediately;

2. When you need to use the system to do simulation experiments, do not need to start from scratch, to use, high efficiency;

3. The experimental environment is quite complex, it is not possible to implement all the experiments in a system environment, so it is necessary to clone multiple system environments to avoid the experimental environment conflict and experiment pertinence.
