Linux Logs looking for shutdown

Hello Friends

I run a couple virtual machines from my home computer, and I noticed at work today that I couldn’t access my file server.

Came home to find my computer had turned off.

Started looking through the logs and I noticed a log gap from 12pm until 5 sometime when i got home and turned it on.

Could anyone dummy check these logs for me to see why it might have been shut down? I don’t see any obvious reasons so I’m guessing a power outage. Although I’m also wondering if one of my roomates came in and shut off my computer lol.

I’ll paste a portion of the logs below.
you all are saints and gods

Look in /etc/fstab (or equivalent) and see what 22F09203F091DD7B is. If that’s your root partition then somehow your root partition got unmounted. That could explain a shutdown/crash.

!
I think you’re right about that. Not sure how I missed it.
Requires further investigation but thank you!

Is this from journalctl or /var/log/messges?

What are you using as your VM Hypervisor?
