Bug detailed description:
--------------------------
With latest kvm, device assignment can not work. Run qemu command with
"-pcidevice" option has no error but we can not see device in guest.

The command I use is like following:

qemu-system-x86_64  -m 256 -smp 1  -pcidevice host=01:00.0 -net none -hda
/share/xvs/var/tmp-img_VTD_ASS_01_1255597645_1

Guest can boot up well but can not find device after boot up.

There is no such issue with commit, d0892e13..-148aa7fb..
