If you are interested in a proof of concept for Microsoft's VDI solution, all you need is a single physical server. People often ask how easy it is to install a complete MS VDI solution and how many servers does it take. George Zhu put together a quick video showcasing just how easy it is to setup all you need on a single physical Windows Server 2008 R2 box. The video uses Windows 7 for the guest. The video is short and to the point, unfortunately, it is a little hard to see at the broadcast resolution. Fortunately, George also posted links to step-by-step guides and scripts used.
