[PATCH v2 03/10] conf: Adding resolution property for model element

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Julio Faracco <jcfaracco@xxxxxxxxx>

New element 'resolution' with parameters 'x' and 'y' were added to
support this settings for VGA, QXL, Virtio and Bochs XMLs. A new
structure was created as Acceleration element has. It is easy to parse
this property. Example:

    <model type='qxl'>
      <resolution x='800' y='600'\>
    </model>
