Un altro passo (giusto) nella direzione dei 64 bit. Se ora anche i prodotti della serie Live, i prodotti di Microsoft Hardware e tante altre cose (come i driver della mia scheda UMTS...) fossero disponibili a 64 bit... sarei felice.
Looks like there is some confusion about our Hyper-V product. The Microsoft Hypervisor is called Hyper-V (as announced today). It will only be available for 64-bit SKUs of Windows Server 2008. Also the Hyper-V standalone SKU is only available for 64-bit.
To take advantage of the Microsoft Hyper-V technology you will need hardware supporting virtualization (Intel VT or AMD-V) and the 64-bit version of Windows Server 2008.
