Say I want to launch a vm with 8GB reserved memory. On a 10-12 GB machine I would have 2 to 4GB of memory left to actually allocate to the system. I don't see how unified memory magically fixes this. It's actually worse because even more memory has to be shared with the GPU. This is like saying a 8GB disk is actually like a 10-12GB disk elsewhere.
