Volete avere Virtual Server a 'gratis'... e vi siete lasciati sfuggire il download su MSDN Universal?
Se comprate Visual Studio Team Edition for Software Testers, ce l'avrete!!! 
Testing
One of the benefits in Visual Studio Team Edition for Software Testers is that it comes with a licensed copy of Microsoft Virtual Server 2005. See this interview on Channel 9 with Tony Donno to see why this is a good thing. Virtual PCs are good for development, too. See this blog article by Mark DiGiovanni for Optimizing Development with Microsoft Virtual PC 2004.
