How can I test S3 without qxl? I tried using cirrus and the Sleep option 
was disabled on windows 7.
I also tried the older qxl (without the patches that support s3), and 
disabled off-screen surfaces (in order to allow s3 to work), and the 
same problem occured.

my command line:
qemu-system-x86_64  -L pc-bios/ -m 1024 -hda <img> -boot c  -vga qxl 
-spice port=5678,disable-ticketing,streaming-video=all -net 
nic,macaddr=00:1a:4a:01:00:e0,model=rtl8139 -net 
tap,ifname=WIN7,script=/local/scripts/lan-ifup -nographic -global 
qxl-vga.debug=1  --enable-kvm -snapshot
