Thanks for the clarification.  All of this is somewhat known to me 
although I did not know there are recent kernel patches that may be 
missing from F20 qxl.ko.

My situation is: dual monitors works (with qxl.ko loaded in the F20 
guest of course) when the guest desktop environment is gnome3, but does 
not work when the guest desktop environment is mate or fluxbox.

I am trying to identify what is different between these two environments 
so I'd like to be able to trace the messages going back and forth to 
some degree.

How can I see the messages being generated/received by spice-vdagentd in 
the guest?

FYI: Host, guest and client are all F20 fully updated (and running on 
the same machine).

Thanks,
David
