VMs Crashing after years of working well

Featured Replies

Recently my VMs (Windows 11, Ubuntu, and Home Assistant) have begun crashing and won't stay running for more than a few minutes. The logs to me are unhelpful, and I would be greatly appreciative of anyone that can assist me in determining the issue that I am having with my home server.

I attached the diagnostics from the machine with the VMS failing to start.

Not seeing anything relevant logged this time, does a newly created VM using the default settings also crash?
