Some updates on the original issue. I checked a lot and I found out that the
issue continued with any version of spice and guest qxl drivers.

I finally digged down to the point that, the qemu comment line which states
"   -global qxl-vga.vram_size=9xxxxxx  " parameter is the problem. When the
guest is started with 9 MB of video memory given as comment line parameter
to qemu, the guest qxldd driver crashes with BSOD.

In my configuration, I changed the video memory parameter to reflect the
following:
-vga qxl -global qxl-vga.vram_size=56623104

Now, it never crashes. My guest resolution is around 1440x900 32bit color.
