[ale] VMs sharing native GPU

[Jim Kinney]

There's some new NVidia stuff that supports virtual GPUs. It works
similar to have VMs work, carve a big system into smaller systems. It's
supported in Ovirt so it's supported by KVM. It does require rather new
GPU and cuda 9+

Every time you stop a school, you will have to build a jail. What you
gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
