Adding a new vgamem attribute looks good to me. Things will be more consistent then and it will certainly be less confusion than trying to use vram instead. The vgamem attribute makes sense for vga, vmvga and qxl. Please leave out cirrus. It is pointless to assign more memory to cirrus, guests would not use it anyway. Removing the confusing vram=9216 default which gets added for cirrus and stdvga and which is never ever used would be nice too. While touching the vga code anyway you might consider adding support for the new '-device secondary-vga' (currently in master / will be in qemu 2.1). That is simliar to stdvga (i.e. it has a vgamem_mb property too). It doesn't occupy the standard vga ports though, so it can be used as secondary display device, like qxl. cheers, Gerd -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
