Hi all,

I found out what crashed kvm when I increased VGA_RAM_SIZE in pc.h. The
crash was caused by a really _dirty_ hack in a kvm specific part of
vga.c (it took me at least an hour to find this amazing piece of code...
at least the HACK ALERT was a good hint ;-) ).
Ow, that really does qualify as a dirty hack. :) Thanks for finding
that! I currently don't have the time to skim through pages of code, so
sorry for my non-involvement on this issue...
@Arne: Could you please test the patch with your setup? I hope it works
this time...
Yesno. It does (at least kvm does not crash), but it shows the same
dialog problems as reported by Leslie:
I've attached the patch. It works for me (tested with windows xp as
guest os @ 1680x1050). As always, please test the patch. I'd highly
appreciate it if somebody could test it with linux as guest os.
BTW, Leslie: Which patch did you use? I attached a second patch as
Andreas forgot to include the changes in hw/pc.h.
Cheers Good morning to the europeans ;)
Arne
