Solve Problems Related to the inability to access the Internet when cloning VM hosts in centos
1. Production Environment

VMWare: 12.1.1

Centos: 6.6 64-bit

2. Requirements

Because we often need to build an environment and conduct experiments, and it takes too long to redeploy the host, the VM clone host function has become the best choice.

3. Problem Description

The host cannot access the Internet after cloning.

4. Solutions

① Run the ifconfig command to check the network card on which the cloned host runs. The eth1 network card is displayed here.

② Cd/etc/udev/rules. d. Run the cat command to view 70-persistent-net.rules and find the MAC address of the corresponding Nic.

2, cd/etc/sysconfig/network-scripts vim ifcfg-eth0

So far, the problem has been solved.
