For more details on this topic refer to the chapter entitled An Overview of VirtualBox 2.

Enable VT-x/AMD-V - Defines whether VirtualBox will take advantage of the hardware virtualization features present in Intel-VT and AMD-V capable processors.

I/O APIC must be enabled when installing 64-bit guest operating systems. This latest generation of interrupt controllers eliminate the 16 Interrupt Request (IRQ) limit present in old Programmable Interface Controllers (PIC).

Enable I/O APIC - Enables support for Advanced Programmable Interrupt Controllers (ACIP).Enable ACPI - Enables and disables Advanced Configuration and Power Interface (ACPI) support for the virtual machine allowing the guest operating system to perform power management tasks on the virtual machine's virtual devices and hardware.Boot Order - Specifies the order in which the virtual machine will search storage devices and the network (using PXE) to locate a bootable operating system image.The Advanced page allows the following settings to be configured: Note that this feature requires that the VirtualBox Guest Additions be installed on the guest operating system (see Understanding and Installing VirtualBox Guest Additions for more details). This page also provides the option to enable OpenGL accelerated 3D graphics for the video adapter.

The basic settings page allows the name, guest operating system type, base memory and the amount of memory assigned to the virtual graphics adapter for the selected virtual machine to be altered. The General category of virtual machine settings consists of four groups of settings arranged on tabbed pages labeled Basic, Advanced, Description and Other:
