How to add a network interface to centos?

Question

linux

I installed centos and did not choose DHCP when configuring the network card. ifconfig only shows this. What to do?

Answer 1

ip link
or the deprecated
ifconfig without options doesn't show all existing interfaces. Yes, and it is recommended not to use them whiter.
Or maybe the driver is not loaded.

Answer 2

I see that this is a virtualbox virtual machine. Have you installed the support package? Firewood on the virtualbox card, in my opinion, is in it.
