Wrote a VboxShutdown Service to shutdown my VirtualBox guests in a savedstate prior to the backup battery being consumed.

VboxShutdown Service
VboxShutdown Service shuts down VirtualBox Guests in a savedstate prior to a power outage event when using CyberPower's UPS Battery Backup.

It provides 15 minutes of runtime to shutdown the system gracefully before total power loss. With their Power Panel software, the shutdown process can be automated.
Although the Power Panel software is able to shutdown the host successfully, it doesn't invoke the script to shutdown my VMs.
So bottom line, I wrote my own systemd service that will automatically shutdown each VM in a savedstate before the host is shutdown.
I'll follow this up with a blog reference once the documentation is completed.
