Hi just had a look at this page - but it looks as if I cannot use this for 
a real hardware display:
""
Client

To connect to a virtual machine using SPICE, you need a client application.
""

Is a hardware monitor capable to display the QXL format? And for my remote 
clients - can I still use VNC?
A change in the guest would be okay, but I still must be able to use the 
existing client environment...

Best regards,

Erik
