 That's what I'm showing right now, but I don't have as many VM's running at the moment. There are currently 8 running and I was getting that issue yesterday when I got around the 15 vm mark.

I'm getting the following error trying to start a VM. I have 64 gb of

problem went away. Below is the error when trying to start a VM and
below that is what my output from "free -g". I don't see why I'm getting
a swap file error when there's plenty of it available.
