Looking on the VirtualBox web site, it states this for running 64 bit guest OS's:<br />
<br />
64-bit-VT or AMD-V capable CPU<br />
Ensure AMD-V is enabled in BIOS

This topic area includes legacy versions of Windows prior to Windows 2000: Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions including Windows Mobile.

Windows OS

Windows Vista is an operating system created by Microsoft as the successor to Windows XP. It was intended for PCs, workstations and laptops, and shares the same code base as its successor, Windows 7. New features included an updated graphical user interface (GUI) and visual style dubbed Aero, a new search component called Windows Search, redesigned networking, audio, print and display subsystems, and new multimedia tools. Vista aimed to increase the level of communication between machines on a home network, using peer-to-peer technology to simplify sharing files and media between computers and devices. Windows Vista included version 3.0 of the .NET Framework, allowing software developers to write applications without traditional Windows APIs.

Windows Vista

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.
