-device qxl-vga,id=video0,ram_size=67108864,vram_size=8388608,vgamem_mb=16
Anyone can help?
You cannot directly set ram and vgamem, but you can modify vram size through vram multiplier. The defaults are as follows: vram_size = 8192 * vram multiplier (2) ram_size = 16384 * 4 vgamem = 16384 * 1 (hopefully got them right) Modifying osinfo[1] property vramMultiplier allows you to change vram size.
