The SPICE Streaming Agent is a guest-side daemon which captures the guest video output, encodes it to a video stream,and forwards the resulting stream to the host to be sent through SPICE. The capture and encoding are done through the use of plugins, so a variety of video format and capture/encoding methods (hardware/software) can be used. For now, spice-streaming-agent only provides software encoding to MJPEG.
In order to set up streaming, qemu needs to expose a
org.spice-space.stream.0 virtio port, associated with a
corresponding Spice port.
In the hardware details, click on "Add Hardware", then select "Channel". Add a "Spice port" device type with the "org.spice-space.stream.0" name. You also need to set "Channel" to "org.spice-space.stream.0"
