The only thin I found about it in that file is :
os.rhel_7x64.devices.display.vramMultiplier.value = 2
That's right. You can add similar lines for other OSes as needed.
I am not sure this file is what I want : from what it seems to only
affects
some parameters at the creation of the OS.
i.e. if I take an ubuntu but I set it up as RHEL7, it won't have more vram.
Video RAM settings should be applied when a VM is started. So if you
set your Ubuntu VM as RHEL7 and then start it, it should get 32 MB of
vram (it works for me).
With centOS7 however (that I have set as RHEL7 at its creation), it
has more vram, but not 2*, really more :
centOS has : "vram_size=33554432" from what qemu says
and all others VM have 8 instead of...33
If vramMultiplier is not present then a fixed value of 8 MB is used.
If it is present then the formula above applies -- note that vgamem is
16 MB, so vram = 2 * 16 MB = 32 MB is indeed the expected value.
