here all was right, juste 01:00.0 and 01:00.1 doesn't work

with Xen 4.4 and last linux kernel from :
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git

Please use the Linus one.
After make an flash bios with an little cable between (+/-)
All is right, I trie to make an pci/vga passthrough
with an Nvidia Nvs 4200m
so for that, I try to give me all chance to have
an pci passthrough in linux kernel.
Why do you thing, it's better to use linus one?
Yes less unstable, but more advanced for Visualization? no?

      

        
that was good until 10-15minutes,
when an moment, .... shutdown...


      

      
Did you launch any guests?

    

    Yes, 2 guest,

    1 ubuntu installation (from disk iso, the lastest in destkop amd64)
    => but after boot no screen on my nvidia (gfx_passtrought try in
    1 and 0)

    01:00.0 and 01:00.1 try in pci passthrough successfully, so just
    "black screen" :) (and other like usb but no disk controller)

    I have the sound but no screen.

    So, Before I used to install linux, I had an windows 7 on the
    computer,

    And after the crash of the first ubuntu boot

    I have try to emulated this win7, but nothing, For the moment It's
    an another problem,

    but is not the subject and not xen problem. (mbr boot I have to
    learn more about)

    

    

      

        
and never can reboot.
no bios access, sadly, I thing the laptop is dead.


      

      
What are some of the PCI devices you passed in? As, in what
does lspci show?

Did you by any chance pass in also your disk controller?

thanks for heard me.
good luck and fine jobs.


      

    

    I think in the end, I can't use pciback or pcistub with nvidia
    Quadro nvs 4200M

    I'm ready to try :

http://wiki.xen.org/mediawiki/images/6/63/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.pdf

    But no nvflash work for save the bin rom nvidia :

    
nvflash.exe
      âsave vgabios.rom => echec unknow rom

      

    

    Just If someone know where I can find the rom for nvidia Quadro nvs
    4200M

    or an generic rom, I'm ready now to make in the end the tutorial
    from :
