I'm taking another look and it looks like the tools may be under another name... xen-tools

I may be going blind at this point if I've missed it this many times.

@kulmacet Can you recreate this with other VMs, or just this specific oracle linux VM? I would spin up a new debian VM for example and shut this problematic VM off, and see if the issue happens with this VM as well. Outside of that, it's really looking like a hardware issue. Also, double check the ILO and BIOS firmware are at the latest. I can almost guarantee it shipped with ancient versions, and many issues like this have been patched relatively recently.
