Welcome to the Hub Community Dean. Another resource that we just launched will help you get started is our Unified Search page (see "Search Extreme" box at top of the page").
As Stephen suggested, there's a fair amount out there on how to set up Virtual EXOS on the Extreme GitHub site:
http://extremenetworks.com/search/#q=virtual%20exos&t=All&sort=relevancy.
Unified Search let's you query not only GTAC Knowledge (as Payton points out), but also the Hub Community, Product Documentation, GitHub, etc.
