Trying to install Virtual OS of XP 64bit on Vista 64bit, ERROR stating CPU is not 64bit

Reported by: dhitchner Owned by:
Component: other Version: VirtualBox 2.1.0
Keywords: x64 error CPU installing Cc:
Guest type: Windows Host type: Windows

Description (last modified by Frank Mehnert)

The message I am getting is:

"Attempting to load an x64 operating system, however this CPU is not compatible with x64 mode. Please install a 32-bit X86 operating system.

Setup cannot continue. Press any key to exit."

My host operating system is Windows Vista 64-bit. My CPU is definitely a 64-bit CPU. I've even had XP 64bit on this computer before. As far as I know, I did everything fine up to this point. I selected XP 64bit as the opperating system to be installed. I gave it 4 Gb of RAM and 125Gb of HD space.

As is clearly documented in the manual you need to enable AMD-V or VT-x on your host system. If you don't have a cpu with either feature, then you're out of luck.

Replying to sandervl73:

Hi

If the hardware vendor (in my case IBM) says (atleast their product leaflets and website) that they support INTEL VT or AMD-V but I get an error "attempting to load an x64 Operating System" then I guess either the problem is at the firmware level (because intel can provide hooks to their CPU to OEM BIOS and it is upto OEM to use those features but if BIOS don't recognize those features then you cant really do anything) or the problem can be that host operating system us not able to propagate the INTEL - VT to virtualbox and hence to the guest OS (in my case windows xp 64bit).

Is there any command at the host OS level (other than BIOS GUI) to know that at the BIOS level if INTEL-VT is enabled or not.

cheers and thanks in advance

Sanjeev

If you attach the VBox.log from such a session, then I can tell you what's wrong.

leifeng, you are running VirtualBox as guest of another VMM, most likely Hyper-V. This is not supported by VirtualBox.
