          Hi,

            
            when I start qemu with "-device virtio-vga,max_outputs=2"
            and connect 

            using spice, I get two windows representing two monitors as
            expected.

            
            However, only one of these works. The other shows "Display
            output is not 

            active.". xrandr says "Virtual-2 disconnected" (consistent
            but not helpful).

            
            Is this supposed to work? If so, what am I missing? Or do I
            have to use 

            QXL in order to use two monitors?

          
          It should work.
          Works for me with Fedora 40 host and Fedora 38 guest.
          Make sure the guest has enough memory.

          
            Better have spice-vdagent installed.
          
          Make sure both monitors are enabled either from inside
            the guest (settings->displays)
            or from the remote-viewer's monitor-icon at the top of
              the window.
          
        
        Try to disable and enable the second
          monitor.
        

    Thanks! Works for me as well now. I shouldn't have tried with
      spicy but with remote-viewer from the beginning.
