I need to catch up to 2009 and want to start using / experimenting with virtualization. there's 3 flavors of microsoft virtualization, right? Vertual server (runs on a server OS as an app to virtualize server or desktop OSs?), virtual PC (runs on a desktop OS as an app to virtualize desktop OSs?) and hyper V (this is where I get lost).
am I right with my descriptions of the software out there? Please correct me if I am wrong on the first 2. AS I chose zones, I saw hypervisor mentioned - that's also virtualization?
what type of machine do I need for good performance? RAM? if I go above 4 GB, I need 64 bit apps to get access to the ram over 4 GB so win 7 or Server 2008 would be needed as the host?
