The libvirt list is not quite the right mailing list for your
question. This list is for discussion about libvirt
development. Better ask at the qemu *user* list when you have problems
with the qemu guest agent.
BTW, 0xc000007b means STATUS_INVALID_IMAGE_FORMAT, which indicates
that either your file is not a valid PE executable or that it's a 32
bit app and tried to load a 64 bit DLL, but that's just a wild guess.
You could use Dependency Walker to track this down.
