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.
