[libvirt] [PATCH v2 04/10] qemu: Include {xres, yres} for QEMU command line

[jcfaracco at gmail.com]

From: Julio Faracco <jcfaracco at gmail.com>

Display devices can use now properties 'xres' and 'yres' by QEMU
command line. Only models specified by their QEMU capabilities. This
commit includes VGA, QXL, Virtio and Bochs.
