To get two monitors you need to run the vm with two qxl devices. The first
one gets created by the "-vga qxl", the second (and more - you can have
up to four) gets created with "-device qxl". The client should pick them
up automatically, the old client knows to close or open a window if the guest
disables or reenables the screen, the spice-gtk client doesn't do that yet
so you will get a number of windows with it anyway.
