Tsirkin" , Gerd Hoffmann , Igor Mammedov , Paolo Bonzini , Andreas =?iso-8859-1?Q?F=E4rber?= , Richard Henderson The BIOS that we ship in 1.6 does not use pci info from host (yet). Several issues turned up (e.g. around winXP boot crashes). So it's safest to disable that interface for 1.6 machine types for now, leave it on for 1.7 so we have enough time to figure out the right way to fix issues if any.
