VirtualBox Networking Configuration

VirtualBox has its own way of Networking that is a bit different than other virtualization platforms.

It's important to understand the distinctions between the types and kinds of networks that are out there and available.

Note: There is a pesky NIC that shows up in "ifconfig", called virbr0. This is a virtual network driver that shows up if you are running libvirtd. You will need to stop and disable libvirtd if this interface is resident, and often times you will need to reboot the box or VM after you do this for the interface to completely disappear from the ifconfig interface listing.
