Starting with version 2.0, VirtualBox supports 64-bit guest operating
systems. Starting with version 2.1, you can even run 64-bit guests on a
32-bit host operating system. The hardware prerequisites are identical
for both cases.

In particular, 64-bit guests are supported under the following conditions:

   1.

      You need a 64-bit processor with hardware virtualization support
      (see the section called “"Acceleration" tab: hardware vs. software
      virtualization”
      <http://www.virtualbox.org/manual/UserManual.html#hwvirt>).

   2.

      You must enable hardware virtualization for the particular VM for
      which you want 64-bit support; software virtualization is not
      supported for 64-bit VMs.

   3.

      If you want to use 64-bit guest support on a 32-bit host operating
      system, you must also select a 64-bit operating system for the
      particular VM. Since supporting 64 bits on 32-bit hosts incurs
      additional overhead, VirtualBox only enables this support upon
      explicit request.

      On 64-bit hosts, 64-bit guest support is always enabled, so you
      can simply install a 64-bit operating system in the guest.

Добрый вечер.

P.S. У меня нет аппаратной виртуализации, а без нее в VirtualBox
невозможно достичь требуемого результата. О чем я и писал.
