Please see the Manual chapter 1.6 or VirtualBox FAQ. You need virtualisation and a few other options. Without that, you can't run 64 bit Guests.

For laptops, this is indeed a tricky thing, but it's for workstations too. My laptop has a VT-x enable CPU, but my mainboard does not support nor provide a Virtualisation function. It might support it, but there isn't in the BIOS. Keep that in mind too.Dest wrote:Not all laptops have virtualization support, you'll have to do some research to find out if yours does.
However if it does, there usually is a setting in BIOS that needs to be turned on. On my D830 it was in the "Posting" section of Bios and was listed as "Virtualization Extension"

Do you have any other virtualisation programs installed, like MS VPC? Only one virtualisation program can use the virtualisation extention at a time (run several VMs with one program can, but not in different programs with VT-x/AMD-V enabled for them).

I am having this issue, as well.
I am using VirtualBox v2.0.2 x64. Virtualization is enabled in the BIOS. VT-x is enabled in VBox.
Here is an image of my settings:

I have ran that VMware tool that checks compatibility and it reports:
"This host is capable of running a 64-bit guest operating system under this VMware product."
Here is a link to my VBox.log:

You missed the link to the Manual/FAQ. It clealy states that you also need I/O APIC and PAE enabled for it to be available. Enable those settings and you're good to go.Dopefish wrote:I am having this issue, as well.

Indeed, but I quote from the manual:Dopefish wrote:I've tried either of those, too, and neither work.
I had actually tried those first. The manual actually states that IO ACPI is only recommended for Windows, it's not required.
So you should enable it. It's advised, though not a dependency for 64 bit support.Warning
You should enable the I/O APIC for virtual machines that you intend to use in 64-bit mode. This is especially true for 64-bit Windows VMs.
If VB is unable to use it, then I would guess that you don't have full virtualisation. But that is strange, as the VMWare tool checks for that.

Well, whether I use those options or not, it does not seem to affect whether I can use 64-bit guests or not.
I filed a bug report here:
http://www.virtualbox.org/ticket/2440
It seems like my BIOS might have broken support for it. :/
