[RFE] Prefer SPICE over VNC when both are configured for a guest
Sometimes it's useful to manage a local box from the cockpit interface without requiring a SPICE client by using the embedded HTML5 VNC client. By adding to the libvirt XML file an additional monitor to have both SPICE and VNC, boxes may use VNC to display the machine instead of SPICE, which is not the best experience due to protocol limitations (no dynamic resizing, no audio, no USB bridging...).
