Subject: [PATCH] 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.
