For Windows VMs, up to four qxl devices can be specified on the command 
line. Linux VMs will see 4 heads on the single qxl device.

You need to specify multiple devices for Windows VMs. This is what 
libvirt gives me (via 'virsh domxml-to-native qemu argv DOMAIN_XML'): 
<...> -vga qxl -global qxl-vga.ram_size=67108864 -global qxl-vga.vram_size=33554432 -device qxl,id=video1,ram_size=67108864,vram_size=33554432 -device qxl,id=video2,ram_size=67108864,vram_size=33554432 -device qxl,id=video3,ram_size=67108864,vram_size=33554432 

For Linux VM, just one qxl device is OK but then it's advisable to 
increase the available RAM: 
<...> -vga qxl -global qxl-vga.ram_size=134217728 -global qxl-vga.vram_size=33554432 

If you don't turn off surfaces, then you should increase vram size to 
say 64 MB from current default of 32 MB.
