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

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.

Yours sincerely,

Mr. Teo En Ming (Zhang Enming)

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!

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

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

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

Thank you very much for your kind assistance.
