Hi, Paolo && Stefan:

When I test the dataplane feature with qemu master, I find= that
Windows (Windows 7 and Windows 2003) VM will hang if data= plane is
enabled. But if I try to start a =46edora VM, it can s= tart normally.

The command I boot QEMU is:
=
x86=5F64-softmmu/qemu-system-x86=5F64 -enable-kvm -m 1024 -smp 2 -dr= ive
file=3Dwin7.img,if=3Dnone,id=3Ddrive-virtio-disk,format=3Dr= aw,cache=3Dnone,aio=3Dnative
-device virtio-blk-pci,config-wce=3D= off,scsi=3Doff,x-data-plane=3Don,drive=3Ddrive-virtio-disk,id=3Dvirtio-di= sk

I found the similar bug has reported some day= s ago:
http://lists.nongnu.org/archive/html/qemu-devel/2013-03/= msg02200.html
. And a patch for this bug has already committed = by Paolo at Mar 13:
http://lists.nongnu.org/archive/html/qemu-d= evel/2013-03/msg02200.html
.

But it ca= nnot work under my environment. Could you give me some advise
t= o debug this problem =3F I can provide more information if need.

I sent a fix and CCed you on the patc= h. Please test it if you have
time.
