Hi "My Work",

With Xspice and Linux X qxl driver, it's easier if only
a single device is used. It supports (given enough memory)
up to 4 monitors per device.

See below for my suggestions on configuration file modifications.

Replace this

with
            Device       "Card1"

My OS is RHEL-6
xorg, spice-server and xspice are built from git (with some minor 
modifications). git describe shows:
xorg-server-1.16.99.901-42-g3e7218a
spice-v0.12.5-45-g69f3f86
xf86-video-qxl-0.1.3-14-gbed5968 (Xspice)

I'm running with spice-vdagent(d) connected to the Xspice session.

After connecting with remote-viewer, click on menu: View -> Displays
and check "Display 2"

Hope that helps,
     Uri.
