Re: [libvirt] [PATCH] qemu: Support ram bar size for qxl devices

Adds a qxl-ram attribute globaly to the video.model element, that changes the resulting qemu command line only if video.type == "qxl". That attribute gets a default value of 64*1024 only if model.type is "qxl". In effect not changing any xml or argv for non qxl devices. For qxl devices a new property is set: -global qxl-vga.ram_size=<ram>*1024 or -global qxl.ram_size=<ram>*1024 For the main and secondary qxl devices respectively. The default for the qxl ram bar is the same as the default for the qxl vram bar, 64*1024. --- I've added a qxl-ram attribute. There is no precedent for adding am attribute prefixed like this, so I'm open for any other suggestion on how to do it.
