Re: Patches for VGA-Passthrough XEN 4.2 unstable

[komkon555 <komkon555@freenet.de>]

Hi. Windows starts with xen4.2 normally as far as pci-passthrough for
VGA-Card is disabled. PCI-passthrough works perfect with other  pci-devices
(lan, sound and s.o.). With pci-passthrough enabled for VGA-Card (meters not
if GFX=0/1) Windows XP crashes. There is my configs:
HVM-client:

#  -*- mode: python; -*-
#============================================================================
# Python configuration setup for 'xm create'.
# This script sets the parameters used when a domain is created using 'xm
create'.
# You use a separate script for each domain you want to create, or
# you can set the parameters for the domain on the xm command line.
#============================================================================

#----------------------------------------------------------------------------
# Kernel image file.
kernel = "hvmloader"

# The domain build function. HVM domain uses 'hvm'.
builder='hvm'

memory = 1024

# A name for your domain. All domains must have different names.
name = "winxpvm1"

vif = [ 'type=ioemu, bridge=xenbr0' ]

disk = [ 'phy:/dev/data/vm01,ioemu:hda,w' ]

device_model = 'qemu-dm'

sdl=0

opengl=0

vnc=1

vncdisplay=1

stdvga=0

serial='pty'

tsc_mode=0

pci=[ '08:00.0' ]

gfx_passthru=1

/boo/grub/grub.cfg:

"xen-pciback.permissive xen-pciback.hide=(08:00.0)
pci=resource_alignment=08:00.0"

Thank you.
