Solution 1

Applicable situations: the problem that the cloned virtual machine cannot access the Internet

Analysis: In this case, it is probably because the network MAC address of the virtual machine has not been modified after cloning the virtual machine.

solve:

1. Enter in the terminal: vi /etc/sysconfig/network-scripts/ifcfg-ens33 (The bold part is the name of your own network card, you can view it with the ifconfig command);

2. Modify or add HWADDR="XXXX" in the file. XXXX is the MAC address of your own network card. You can use the ip addr command to view it.

Solution 2

Applicable situations: solution one cannot solve the problem

Solution: Start a service named NetworkManager-wait-online after booting (command: systemctl enable NetworkManager-wait-online.service)

Solution Three

Applicable situations: Solution 2 cannot solve the problem

Analysis: I don’t know why, but Baidu has a solution to my problem. You can also try it.

solve:

1. Turn off network management in configuration (chkconfig NetworkManager off)

2. Turn on network management in configuration (chkconfig network on)

3. Close network management in the service (service NetworkManager stop)
