Hi,

you can only use 64-bit guests if you have a cpu which supports hardware
acceleration.

>From VirtualBox manual:
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.)
