1: Because you are cloning virtual machine or directly to use someone else's CentOS operating system directly open to their local virtual machine, network card may be eth1 instead of eth0, below simply write how to change eth1 to Eth0, the steps are as follows;2: If you are cloned, then the MAC address shown below will be different, if it is directly open the CentOS operating system of others, MAC address is the same. In fact, this network card with eth1 or eth0 influence is not very big, look a
