 ==== Graphical Overview ====
 As a picture paints a thousand words, let us look at what we are dealing with graphically.
+\\
+\\
+Imagine for simplicity, you wanted each Physical Interface to map to an interface in your VM. Lets say you have 3 Interfaces in your VM, you would have something like this.

+\\
+{{ :single_int.jpg?450 |}}
+\\
+Now while this is valid, consider that I am passing data from VM1 to VM2, I would need, with 2 data ports per VM, four data ports. What would be better is if I put the data out of VM1 and data in of VM 2 in a port group, that shared a single interface.
+\\
+\\
+In the example below we can see that the third physical interface is connected to both VMs (the yellow lines) and both of these interfaces are in the same Port Group. This means we shared data between the two VMs using only a single port.

+==== Three Server Example ====
 Consider my example below, I three servers, all connected to a switch, and I am passing multicast traffice between them, that is being processed in a particular way at each stage. Basically I want an input, two processing stages, a storage device and an output.

 There are three Network Adapters that have been added to each VM (this is for the MFEL VM). Each network has then been assigned to a Port Group (so you need to create your Port Groups and Switches before your VMs).
