Re: [Xen-devel] Requesting Assistance from Intel Engineers on Intel Integrated Graphics (IGD) VGA Passthrough for Xen 4.0.1-RELEASE and pv-ops dom0 kernel 2.6.32.x

["Mr. Teo En Ming (Zhang Enming) 张恩鸣 of Singapore" <space.time.universe@xxxxxxxxx>]

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". Full details of the error are in the short video clip.

Please watch my Youtube video at the following link:

At the time of this writing, there are 24 uploaded videos in my Youtube account.

Please let me know what you think after watching the short video clip.

Thank you very much.

Dear Intel Engineers,

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
messages in threads in the xen-devel mailing list in August 2010 and
September 2010.

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.
