Using a 64bit guest in a 64bit host isn't possible without hardware virtualization on the host processor. Will this be changed in future versions of Virtualbox ?
(i.e. Windows-7 XP-mode showed the same behaviour in the first revision, but has been changed by now)

Unlikely.
Two reasons:
1. Developing software virtualization for 64-bit guests is very difficult task
2. Nearly all modern CPUs support hardware virtualization

Re: 64bit Host - 64bit Guest without hardware virtualization ?
There is quite a significant family of Intel Atom processors that support Intel 64 (x64) and not VT-x. In fact, currently there are no Atom processors that support both Intel 64 and VT-x (there are some that support VT-x and some that support Intel 64 however).Technologov wrote:2.

Re: 64bit Host - 64bit Guest without hardware virtualization ?
Actually, Windows Virtual PC has never supported 64-bit guests. It only supports 32-bit XP, Vista and 7. I believe that hardware virtualization is required for 64-bit guests in any virtualization solution.gusgan wrote:(i.e. Windows-7 XP-mode showed the same behaviour in the first revision, but has been changed by now)

That's right, only 32-bit guests are possible, but hardware virtualization is no more needed mandatory.
