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, 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

00:00:28.334 ******************** End of CPUID dump **********************
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,
David Losada (Ringmaster)
