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.

[ovirt-users] video memory in virtual machine

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.
