Adding ethernet port to the virtualbox on ubuntu os?

Question

I am using VirtualBox with Ubuntu version 14 installed in it. I have created 4 virualbox ports vboxnet0,1,2,3.

I would like to add 2 new ethernet ports in Ubuntu to assign each ethernet port to a vboxnet , I am already having eth0 and eth1, I would like to add 2 more ethernet ports, please help?

Answer 1

They should already be there - just unplumbed. Add suitable stanzasin /etc/network/interfaces.

When you run ifconfig in the guest OS, do you see the extra interfaces?

And just to clarify, do you mean that your VM has four ports, and you would like Ubuntu, which is the guest OS installed on the VM, to be able to use all four ports, so that you have something like eth0, eth1, eth2 and eth3? Bear in mind that for some kinds of virtual port - such as bridged - you need to have actual real ethernet ports on the host machine!
