How can I allocate a fixed IP address for an Ubuntu Server 12.04 guest OS running in Virtual Box?

I've seen this question but it doesn’t address using a “Bridged Adapter.”

The virtual machine is currently getting an IP in the range 192.168.10.x and I want it always to be

You could literally copy and paste that answer but substitute 'Host-only' for 'Bridged'. – Tanner Faulkner Jul 31 '12 at 23:44
Does the VM get its IP address via DHCP from the router? If so, what model router is it? – Paul Aug 1 '12 at 6:55

When you give a VM a Bridged Adapter, its affectingly like giving it its own NIC connected directly to your network.

The Ubuntu installation inside of the VM needs to be set to use a static IP address. This is done in the /etc/network/interfaces file. Some information about the interfaces file can be found on this page:

Here is an example interfaces file configured to match your question:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static

After making modifications to /etc/network/interfaces, restart your VM for the changes to take effect.
