Windows QXL Display Driver

[Geoffrey McRae]

Hi Gerd,

Over the past few weeks I have been adding spice display support to 
Looking Glass as a fallback mechanism for during system boot (or diags) 
before our application is loaded in the guest VM. The idea is to have 
the VFIO GPU duplicate it's output to the QXL device, which works fine 
until you load the QXL display driver.

The issue is that once the driver is loaded windows removes the option 
to duplicate the output. Is this something that needs to be tweaked in 
the driver to allow this? or is there a technical reason why this can't 
be done?

Kind Regards,
Geoffrey McRae
