Dear James Harper,

I had Xen GPL PV drivers uninstalled but the system was still very unstable.

Can you try it on a machine that has never had gplpv installed? That 'Xen pci 
device #0' device looks like GPLPV is trying to handle the PCI passthrough, 
which it shouldn't.

Engineers on Intel Integrated Graphics (IGD) VGA Passthrough for Xen 4.0.1-
RELEASE and pv-ops dom0 kernel 2.6.32.x

( EDIT: In case my email attachments are too big, I have uploaded my
screenshots to image sharing sites.

Here are the links:

Dear All,

I have barely managed to install Intel Graphics Media Accelerator (GMA)
Drivers because the system is unstable and Windows XP Home Edition HVM domU
keeps crashing with a BSOD after a short while. I have attached three
screenshots of the Device Manager in this email. You may refer to these
screenshots (JPEG images). These screenshots indicate that Intel integrated
graphics (IGD) VGA passthrough with Xen 4.0.1-RELEASE and pv-ops dom0 kernel
2.6.32.21 is successful (albeit the system is very unstable).

I have also uninstalled an older version of Xen GPL PV drivers for Windows XP
and installed gplpv_XP_0.11.0.213_debug.msi.

At the moment, the system is very unstable and Windows XP HVM domU keeps
crashing with a BSOD after a short while. It also takes at least three minutes
for Windows XP HVM domU to start booting after the "xm create" command is
executed. Sometimes, Windows XP HVM domU may not even start after the "xm
create" command is executed, so I will just have to keep rebooting.

I have tried memtest86 scan with 2 passes and the test results indicate that
there are no hardware memory errors. I have also performed a bad sector scan
in Windows XP HVM domU and the results are negative.

        Dear Pasi, Intel engineers, and Xen developers,

        I have just made and uploaded a video to Youtube. The length of the
video is only 1 minute and 37 seconds. The video demonstrates the successful
bootup of Windows XP Home Edition HVM domU/virtual machine, indicating an
initial successful Intel integrated graphics (IGD) VGA passthrough, and
followed by a BSOD shortly thereafter. The error in the BSOD is
"IRQL_NOT_LESS_OR_EQUAL

the short video clip.

        Please watch my Youtube video at the following link:

                                I am unable to get Intel integrated graphics 
(IGD)
VGA passthrough to
                                work with Xen 4.0.1-rc6-pre, Xen 4.0.1-RELEASE, 
pv-
ops dom0 kernel
                                2.6.32.19 and 2.6.32.21. The moment the command 
"xm
create<Windows XP
                                HVM guest>" is executed, the screen immediately 
goes
blank with the
                                label "NO SIGNAL". It may take anywhere from 
3-10
minutes before Windows
                                XP Home HVM domU starts booting. The HVM guest 
will
subsequently crash
                                with a BSOD.

                                I have posted configuration files, scripts, 
logs and
kernel debug

                                Please assist.



                        A couple of questions:

                        - I assume the IGD is the primary graphics?


                Yes, the IGD is the primary display adapter.


                        - Do you have other graphics adapters in the same 
machine?


                Yes, I have NVIDIA GeForce 8400 GS PCI Express x16 graphics card
in the same machine.


                        - Can you please paste "lspci -vvv" from dom0.
