[Libguestfs] Windows 2003 BSOD, 0X0000007B bug

Hello, In last November, Richard helped me and succeed in P2V-converting a windows 2003 server towards an oVirt/RHEV image. Recent upgrades solved many ssh issues https://bugzilla.redhat.com/show_bug.cgi?id=1167774, and conversion seems OK now. The server I converted is now booting and running fine every time. I used the very same procedure on two others 2003 servers (one in x86 and one in 64 bits), and both are showing BSOD and the very well known 0x...7B bug. As it is a very known bug, I tried all that is available on earth to try to cope with it : - before P2V, log as local admin, merge the mergeide.reg into the registry, reboot, then halt and P2V - before P2V, boot and install the different libraries viostor, net, ballooning, and so on... then reboot, then P2V - in the P2V iso GUI, disabled the conversion of every device except the disk (remove floppy, NICs, CDROM) - once converted and imported into oVirt, set the disk driver as virtio, ide, iscsi... BSOD remains... I could give you every version of every parts used in the process, but to make it short, let say that everything is up to date, nothing may be more aged than two months. I don't know what I could try next, as I think I tried everything I read about. -- Nicolas Ecarnot
