Fix Issues with Networking for Ubuntu VirtualBox Server
Networking stopped working for my Ubuntu VirtualBox Server (running on Mac OS X) and it couldn't seem to get it working again. Tried running:
sudo /etc/init.d/networking restart
only to get errors about "Failed to bring up eth0..." until I found a workaround on howtogeek.com, which worked to solve my issues like a charm! Thanks How-To-Geek
Quick Summary:
Run this command to edit the interfaces file, and then change eth0 to eth1.
sudo vi /etc/network/interfaces
Run this command to restart networking and everything should likely start working again:
sudo /etc/init.d/networking restart
You should be able to run a ping command and validate the connection is working. One thing to note... this worked the first time the Virtual Machine was moved, but then I exported it again to another Mac and had to modify what I did slightly. I ran:
ifconfig -a
and noticed that the system now labeled the ethernet connection I needed to use as eth2, so I edited /etc/network/interfaces file one more time using eth2 as the interface.
