Occasional out of memory shuts down VM.

[bobbintb]

This deals with Docker and VMs but is mostly general. I have 128GB of RAM, 64 of which is allocated to a VM. I don't have many Dockers but a few times when trying new containers or doing some dev stuff, my VM was stopped Unraid reported it was out of memory. It always shuts off the VM, and not cleanly. That's the last thing I want. Is there some way to set it to never do that? I would have thought it would just allocate the remaining 64GB as needed but it seems to be over allocating.
