  I don't remember how the check is exactly done but basically the
agent is complaining that you have more than 1 cards.
How many Gpu cards did you assign to the guest and with which types?
Looking at the code the error string is in
src/spice-streaming-agent.cpp checking the response of
get_device_display_info call to the plugin.
The agent can load multiple plugins and choose the best one based on
client codecs and other information. By default there's a mjpeg plugin
(mainly for fallback) and installed a GStreamer plugin. If I remember
(but maybe I'm wrong) they use Xorg/X11.
