VirtualBox's 64-bit guest support (added with version 2.0) and multiprocessing (SMP, added with version 3.0) both require hardware virtualization to be enabled. (This is not much of a limitation since the vast majority of today's 64-bit and multicore CPUs ship with hardware virtualization anyway; the exceptions to this rule are e.g. older Intel Celeron and AMD Opteron CPUs.)

Processor Support for 64-Bit Guest Operating Systems
When you power on a virtual machine with a 64-bit guest operating system, VMware Player performs an
internal check. If the host CPU is not a supported 64-bit processor, you cannot power on the virtual machine.
VMware Player supports virtual machines with 64-bit guest operating systems, running on host machines with
the following processors:

• Most AMD64 processors (except the earliest revision C Opteron processors)
  
• Intel Pentium 4 and Core 2, and Core i7 processors with EM64T and Intel Virtualization Technology
  

VMware also provides a standalone utility that you can use without VMware Player to perform the same check
and determine whether your CPU is supported for VMware Player virtual machines with 64-bit guest operating
systems. Download the 64-bit processor check utility from the downloads area of the VMware Web site.
