"Bug" on Virtualbox 1.5 with Via C7 CPU: Can't run XP guest

[ringmaster]

It was discovered in february this year as Heike C. Zimmerer wrote (see: ​http://www.mail-archive.com/vbox-users@virtualbox.org/msg00423.html ), but it's still a problem. When I install Win XP SP2 as guest on Kubuntu 7.10 host with a C7 Esther processor it refuses to install.

With my previous C3 Samuel without cmov Virtualbox 1.4 WinXP run perfectly (vmplayer complained), but now with C7 (it's like a i686) I can't run it...

Description of the problem: I think that Virtualbox passes a CPUID that this broken XP misunderstands with another CPU, so refuses to continue:

| Windows requires certain processor features that are not available | on the processor in this computer. Specifically, Windows requires the | following instructions. | | CPUID | CMPXCHG8B | | Setup cannot continue. Press any key to exit.

I know that probably it is a problem of buggy windows, but natively it runs, so please change the reported CPUID to make it run. Thank you for your attention. I usually support the projects that I enjoy, with money or help, and this project will have a brilliant future (virtualization will be a must soon).

Kind regards from Spain,

I wrote bug #4874 describing what is happening. It is NOT VirtualBox's bug, you need to go into your BIOS.
