Dang! it is Intel's fault for requiring HW VT support to run 64bit guests.
Intel EM64T CPUs do not have segmentation support in long mode. If the Intel EM64T CPU is VT-capable, it comes with hardware virtualization support (Intel's Virtualization Technology). This hardware virtualization support allows Workstation and VMware Server to work around the lack of segmentation, making it possible to run 64-bit guest operating systems on Intel EM64T VT-capable CPUs.

Vista_X64 and Srv08_X64 took a few start attempts to recognize the Virtualbox setting changes but it worked.

Cheers for the IOACPI tip Guys :D

Thanks to Nille02, it appears that the approach adopted by VBox is broadly the same as VMware, and that both can only support 64-bit guests if the processor supports VT-x (Intel) or AMD-V (AMD) and the BIOS hasn't disabled Virtualisation. See the VMware paper Processor Check Utility for 64-Bit Compatibility which references the utility which does this check.

It works, but... From time to time, the host crash with the following blue-screen:
Host: Intel Core 2 Duo E8400 3.0GHz, 8GB, Vista x64 SP1, VirtualBox 2.
Client: Vista x64 SP1, 2GB.

Any idea?!?

:cry:

Yanew, Please don't cross post. We're having difficulty enough coping without you asking the same Q multiple times because we're overloaded. I've deleted the duplicate. Read the 70 odd tickets raised so far on 2.0 bugs. 64-bit support is new in 2.0 and is pretty unstable. Hopefully it will be better in 2.0.2

Nah, there is a Vista x64 driver for AC97. Below is a link that leads to the driver download from the Realtek site, but I'm sure there are other sources. I've tested this on Vista x64 and it works.

Hey, I didn't post that, it was Stefan.becker. Use the proper quote box next time! :evil: :P

I will update your post to reflect the correct poster. Same goes for Stefan's.

Hi,

I am getting that same problem trying to install Vista 64 on Kubuntu 64.
