              I tried to setup a
                multi-head guest, but I’m having trouble getting

                multiple displays to work correctly

                
                For Jonathon, the part that I had trouble with was
                adding “heads =

                ‘4’" to the video / QXL configuration. I don’t see it
                documented in

                https://www.spice-space.org/spice-user-

                manual.html#_multiple_monitor_support.

              
              Yep, it's a fairly new feature. I'm working on additional
              multi-monitor 

              documentation and will be sure to include that.

            
            Yep, we totally missed it
              when 'heads' support was added :( virt-manager

            UI needs to be able to set
              this too..

            
        Ah, that was my next question ;-)

        
                For Christophe F, what I get with the configuration
                file http://paste

                bin.com/FEXbjaE3 is shown in the
                following picture https://redskincat

                .wordpress.com/2017/02/27/learning-more-about-mesa/#jp-carousel-1224.

                As far as I remember, this is pretty much a default
                configuration of

                Fedora 25 after install from the live CD. If I
                understand correctly,

                the difference with you is that I actually installed.

                
                Does anybody else see this? If not, what could be wrong
                with my

                setup?

                
              I don't see anything obviously wrong with the
              configuration. If you

              close the spice client and immediately re-connect does it
              still show

              the same thing in both windows?

              
              Can you capture the debug output of running virt-viewer
              with the --

              debug and --spice-debug options while you enable the
              second monitor?

              That might give a clue about what's happening.

            
            Also, what window manager are
              you using on the client? The window

            decorations don't look like
              default GNOME setup? The linux client is

            running on bare-metal, not in
              an osx VM?

          
        This is Cinnamon. The Linux client is running on the same
          Fedora 25 host.
      
    
    My client is on cinnamon too...   i forgot to mention it :-[

    
        So I thought I’d test with Gnome. It did not let me log-in.
          Tried with Gnome on Xorg. Same. Could not log in in Cinnamon
          anymore either… So I rebooted. And my machine landed in the
          emergency shell. My journalctl log is full of btrfs errors.
          The machine seems pretty sad.
        

        Of note, this was my “stable” Linux machine so far, the
          only one that did not have some flaky component… I have three
          hosts (four if you include the Mac), they all have something
          wrong:
        

        - The “Shuttle” machine is unstable, always have been. I
          hoped it would improve by swapping RAM or graphic card, but
          did not.
        

        - The “Big” machine has new “bad sectors” on the boot hard
          disk daily. I have bought a new disk, did not have time to
          install it yet.
        

        - The “Muse” machine I was using here was the most stable
          one, if the oldest. So far, it had performed flawlessly. Grrr.
        

        If I can bring Muse back up, I’ll tell you if the result is
          different on Gnome. Meanwhile, I’ll try the heads=4 setup on a
          new VM on Big (which is Gnome by default)
