The Quick Start VM has a Notice: These are 64-bit VMs, and require a 64-bit host OS and a virtualization product that can support a 64-bit guest OS.
It is not enough just to have a 64-bit host OS, but the host OS is required to support hardware virtualization. Installing the Quick Start VM on Oracle VirtualBox installed on a 64-bit host OS might still generate an error.
To be able to install the Quick Start VM the following two requirements are prerequisite.
Some software tools are available to test if a platform supports Intel Virtualization Technology. The Intel Processor Identification Utility (http://www.intel.com/support/processors/tools/piu/sb/CS-014921.htm) may be used to test if the CPU supports Intel Virtualization Technology. On Windows systems hardware support for virtualization may also be tested with Microsoft Hardware-Assisted Virtualization Detection Tool (http://www.microsoft.com/en-us/download/details.aspx?id=592).
Virtualization support must also be enabled in the BIOS. Some Windows systems that do not support hardware virtualization in the processor may have a “Virtualization” option in the BIOS, which is not the same as the Virtualization Support option for Intel Virtualization Technology
