That means: if gfx passthroughed, disable emulated VGA. For another question about loading VGA bios, given you have saved the VGA B= IOS of your card to vgabios-pt.bin, you should first put it at xen-unstable= .hg/tools/firmware/vgabios/, and also you needs following changes, at last,= you still need to pass BDF of gfx to rombios per firmware spec. diff -r 494be76c1ad9 tools/firmware/hvmloader/Makefile --- a/tools/firmware/hvmloader/Makefile Thu Aug 27 16:54:33 2009 +0800 +++ b/tools/firmware/hvmloader/Makefile Thu Aug 27 17:22:01 2009 +0800 @@ -50,6 +50,7 @@ roms.h: ../rombios/BIOS-bochs-latest ../ roms.h: ../rombios/BIOS-bochs-latest ../vgabios/VGABIOS-lgpl-latest.bin \ ../vgabios/VGABIOS-lgpl-latest.cirrus.bin ../etherboot/eb-roms.h sh ./mkhex rombios ../rombios/BIOS-bochs-latest > roms.h + sh ./mkhex vgabios_pt ../vgabios/vgabios-pt.bin >> roms.h sh ./mkhex vgabios_stdvga ../vgabios/VGABIOS-lgpl-latest.bin >> roms.h sh ./mkhex vgabios_cirrusvga \ ../vgabios/VGABIOS-lgpl-latest.cirrus.bin >> roms.h diff -r 494be76c1ad9 tools/firmware/hvmloader/hvmloader.c --- a/tools/firmware/hvmloader/hvmloader.c Thu Aug 27 16:54:33 2009 +0800 +++ b/tools/firmware/hvmloader/hvmloader.c Thu Aug 27 17:23:00 2009 +0800 @@ -688,9 +688,9 @@ int main(void) vgabios_sz =3D round_option_rom(sizeof(vgabios_stdvga)); break; case VGA_pt: - printf("Loading Gfx Video BIOS from 0xC0000 ...\n"); - vgabios_sz =3D - round_option_rom((*(uint8_t *)(VGABIOS_PHYSICAL_ADDRESS+2)) * = 512); + printf("Loading Gfx Video BIOS from file ...\n"); + memcpy((void *)VGABIOS_PHYSICAL_ADDRESS, vgabios_pt, sizeof(vgabi= os_pt)); + vgabios_sz =3D round_option_rom(sizeof(vgabios_pt)); break; default: printf("No emulated VGA adaptor ...\n"); Teo En Ming (Zhang Enming) wrote: > Dear Weidong, > > I have read through the technical papers on VGA passthrough presented > by the University of Amsterdam and the University of Michigan and > thus gained a better understanding of VGA passthrough in Xen. > > For my preferred setup, I would not be able to adopt the guidance > provided by the University of Amsterdam.
