commit 161212ef02312c0681d2d809c8ff1e1f0ea6f6f9 Author: Fabio Fantoni <fabio.fantoni@m2r.biz> Date: Wed Apr 29 11:20:28 2015 +0200 libxl: Add qxl vga interface support for upstream qemu Usage: vga="qxl" Qxl vga support many resolutions that not supported by stdvga, mainly the 16:9 ones and other high up to 2560x1600. With QXL you can get improved performance and smooth video also with high resolutions and high quality. Require their drivers installed in the domU and spice used otherwise act as a simple stdvga.
