→Running 64-bit VirtualBox Guest Operating Systems
Before looking at the supported guest and host operating systems it is important to first cover some requirements related to running 64-bit guest operating systems in VirtualBox virtual machines.
Firstly, 64-bit guests require that the host hardware support hardware virtualization in the form of AMD-V or Intel-VT capable CPUs (see [[An Overview of VirtualBox 2]] for more information on hardware virtualization).
In addition, if a 64-bit guest operating system is to run within a virtual machine on a 32-bit host (a feature now supported by VirtualBox), the option to install a 64-bit guest must be specifically selected for the target virtual machine.
