I have Windows 7, and I need to setup a dev environment consisting of multiple server OSes: I need a PerformancePoint 2007 server, a MOSS server, and a SQL Server, and a domain controller (might be my SQL Server, not sure yet). This is just to replicate a bug in production.
Anyway, what should I be using for my virtualization needs? I have Windows Virtual PC, but can it have 64-bit guests? I need a free solution, even if it's a free trial.
