Image Creation Tutorial

This tutorial will cover building a new image for use within FIREWHEEL. This requires two steps. First, building a new virtual machine disk from an ISO file. Second, creating a new model component so that the image can be included in a topology file. Lastly, there is an optional step to optimize the image size. This step speeds the process of transferring images around the FIREWHEEL Cluster and saves disk size by ensuring that the VM disk size is as small as possible.
