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

From: Julio Faracco <jcfaracco(a)gmail.com&gt; 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'\>
