Hi, 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. Frediano
