Re: [ovirt-users] Changing video memory size

Is there a way to change it for all os in a row ? something like
"os.all.devices.display.vramMultiplier.value = 2"
Try `os.other.devices.display.vramMultiplier.value'.
How is that memory used on the hypervisor ? Will this use the
physical vram for
the same amount or will it use the physical RAM ? i.e. if I set all VM to 32,
can I reach the limit of the resources from my hypervisor quickly ?
It depends on how the video RAM is used in the guest OSes and their
drivers. The allocated memory is unlikely to be used all immediately
but it's available to the guest OS and it can use it for many different
purposes, up to the amount you provided. So it's better not to set
unnecessarily large video RAM values and limit them just to the amount
needed (and that optimum value may differ for different OSes or even
different versions or configurations of the same OS).
So basically, I must create a 01-defaults.properties file ? Will it
ovewrite
only parameters I change in that file, or will it totally replace the whole
configuration with my new file ?
I think it should just add/override the specified parameters, not
replace the whole configuration.
