I checked DomU with and without msi and with msi i saw bluescreen and
turning it off, and DomU again start normally. Like I wrote, I also
have different kernel for Dom0, with 3.3-rc7 i had error 43 and today
first time installed xen 4.2.1-pre( from source). Yesterday and days
before that i had xen 4.2-rc2 -- 4.2-rc4. Im not 100% sure what
(kernel or new xen) fixed problem and for now i will play with windows
7, maybe tommorow or day or two later i will again reinstall Dom0 to
check which one solved problem. In mean time at least we know that its
possible to pass vga to windows 7 DomU, and how. Im sure that You and
maybe other users will try on her own system with settings I
described. There was also few more things i did just before i had
success, but i think it has nothing to do with it. Just mention it:
- removed opencl libraries under windows system,
- removed cuda libraries under windows,
- reinstall nvidia drivers to version 275.33 (there was 306.xx or
something, dont remember)
