Ubuntu Server Does Not Recognize VirtualBox Adapter

| Comments

As we know, VirtualBox provides several adapters that we can add and be used by OS guest. At the time of writing this post, I have an OS X (host) and Ubuntu Server 16.04.1 LTS (guest). The needs are, I want to be able to remote my Ubuntu from OS X terminal. I also want my Ubuntu guest can connect to internet. I have configured two network adapters for the guest (NAT and host-only).

When I run

1
$ ifconfig

The first/default adapter (NAT) enp0s3 is recognized without any problems by the guest. But not the second one (host-only). To make the second adapter visible, I have to run a command

1
2
$ sudo dhclient
$ ifconfig

Now I got both adapters enp0s3 (NAT) and enp0s8 (host-only) visible on terminal. And now I can ping and run ssh from host (OS X) to guest (Ubuntu server).

In order to make it permanent, we need to edit /etc/network/interfaces with the following lines

1
2
3
# The second network interface
auto enp0s8
iface enp0s8 inet dhcp

Then restart the network service by running

1
$ sudo /etc/init.d/networking restart

That’s my note for now and thanks for reading.
