I've seen windows XP hanging on reboot/shutdown like this so many countless times I'd not bother with this at all. At least, does clean install of winXP shows the same behavour?

At that point qemu is using 100% of one host CPU, about 85% user, 15% system. (Core 2 Quad 2.66GHz) This is the command line I use to start qemu: qemu-system-x86_64 -hda winxp.img -k en-us -m 2048 -smp 2 -vnc :3100 -usbdevice tablet -boot c -enable-kvm &
