I have found that playing video is not fluent in the virtual machine.
So I thought maybe too small video memory in virtual machines led to this. Some parameters
have been found when I was trying to check some information. So I wonder where to modify
them and if it works to do this.
-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.
