Re: [Xen-devel] Dear Tobias Geiger, I Need Help with Xen VGA Passthrough to Windows 8 Consumer Preview / XP (Xen 4.2-unstable)

["Teo En Ming (Zhang Enming)" <singapore.mr.teo.en.ming@xxxxxxxxx>]

Dear Tobias Geiger,

You mean my problem cannot be solved at all (as regards to the yellow exclamation mark with NVIDIA Geforce 8400 GS and CANNOT run 3D graphics benchmarks)? I DO NOT have this problem back when I was doing Xen VGA Passthrough to Windows XP HVM domU with Xen 3.5-unstable. Yes, 3 years ago, back in the year 2009, with Xen 3.5-unstable. Back when Han Weidong was still around in Intel Corporation.

I am surprised that you are unable to open my Xen VGA Passthrough Version 1.6 PDF documentation. I have tried opening the file attachment myself and it is not empty.

To solve the problem with your email client, I am providing the Xen Wiki link to my Xen VGA Passthrough Version 1.6 PDF documentation.

Xen WIKI link: http://wiki.xen.org/wiki/Xen_VGA_Passthrough_to_Windows_8_Consumer_Preview_64-bit_English_HVM_domU_and_Windows_XP_Home_Edition_SP3_HVM_domU_with_Xen_4.2-unstable_Changeset_25070_and_Linux_Kernel_3.3.0_in_Ubuntu_11.10_oneiric_ocelot_amd64_Final_Release_Dom0

You can also watch a Youtube video of my partially successful Xen VGA Passthrough to Windows 8 Consumer Preview HVM virtual machine.

Xen WIKI link: http://wiki.xen.org/wiki/Video:_Xen_VGA_Passthrough_to_Windows_8_and_Ubuntu_11.10_with_Xen_4.2_and_Kernel_3.3

Please do help to read through my Xen VGA Passthrough Version 1.6 documentation to see if there are any mistakes, ESPECIALLY MMIO BARS pBAR:vBAR 1:1 mapping.

Thank you very much for your prompt response and kind assistance.

Dear Teo,

your problem is "known". unfortunatly no "known" solution exists.
of course you can try to find one - but that involves much try-and-error on 
your side. 
The "easy" solution would be: replace your NVIDIA card with a recent ATI one.

Besides the fact that i can't open your PDF (empty file...) it's really really 
annoying - for various reasons; first: nobody can edit the PDF except you. 
second: now your pdf is stored in thousands of mailboxes in various versions - 
if it were a wiki-article or anything else web-based, it would be there only 
once. i love things which have a definite place...
please consider the suggestion many others already made to bring your good 
intended documentation effort to a technical state and place where everybody 
has the maximum profit of it: WIKI

Thanks and Greetings to Singapore!
Tobias

Dear Tobia Geiger and Xen users and developers,

My Xen VGA Passthrough to Windows 8 Consumer Preview and Windows XP HVM
domU is only *_partially_* successful. There is a yellow exclamation
mark besides NVIDIA Geforce 8400 GS in Device Manager. Device Manager
reports:

Windows has stopped this device because it has reported problems. (Code 43)

This device isn't using any resources because it has a problem.

I suspect the above problem has to do with MMIO BARs pBAR:vBAR 1:1 mapping.

Could you read through my attached "Xen VGA Passthrough - Version
1.6.pdf" documentation carefully to see if there are any mistakes in
this area? Of concern are Sections 3, 4, and 6 in my Xen VGA Passthrough
documentation.

I am using Xen 4.2-unstable changesets 25070 and 25099 and Linux Kernel
3.3.0.

Thank you very much for your kind assistance.
