Regression in latest git-HEAD

Regression in latest git-HEAD

[Gregory Haskins]

Hi All,
  FYI: It appears that recent checkins have regressed VMX for running linux.  As of May 1st I could boot 64 bit SLED.  As of yesterday, it exceptions immediately in the bootloader.  This happens both with and without my APIC patches applied.

Any idea of what checkin was the cause?  At least, which release was the

Can you provide a link to an image (or an installer)?  I'd like to debug 
this.

%esp is 0x87bdc, beyond the 16-bit limit.

Anyone have an idea as to what is going on?  Does isolinux (at least the 
version in the SLED installer) look at the acpi tables?  I find it hard 
to believe.

Re: Regression in latest git-HEAD

[Makoto Dei]

Hello,

I have the same problem with Linux which is using isolinux,
such as Ubuntu.  I checked the BIOS in the latest KVM and
I found that it seemed to be missing the following change.

http://bochs.cvs.sourceforge.net/bochs/bochs/bios/rombios.c?view=log#rev1.172


I can boot isolinux on the latest KVM with the BIOS with this change.


Thanks,
Makoto Dei

Thanks for the hint.  I regenerated the bios from the latest bochs 
sources, hopefully this is an improvement.

The SLED installer (which detects it is being virtualized and disables 
bootsplash?!) still doesn't get very far, but it isn't any different to 
the old bios.
