It isn't that simple. The vga framebuffer can be used as as video memory in non-vga mode too. Guest driver can choose whenever it uses the vga framebuffer or vram bar. Traditional behavior is to use the vga framebuffer, in fact very old qxl device revisions don't have a vram pci bar in the first place. Because of that vgamem_mb should be configurable on qxl too. cheers, Gerd -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
