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

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!
