Microsoft Hyper-V Server: How to Get It
Microsoft Hyper-V Server 2008 R2 is a stand-alone product that will be available via the Microsoft Download Center free of charge.
Microsoft Hyper-V Server 2008 R2 does not require CALs for the product itself.
Micro$oft is determined to match VMware at all cost :)
If hyper-v only supported mapping of USB ports,
every windows computer should have this!
Imagine "web browsing" VM, or "freeware software" VM.
Used as "disposable", revert to clean state every time they are used...
In fact Windows 7 (pro) does have Windows XP VM embedded,
but I think it does not provide mentioned "revert to clean" options...
