Help me understand Device Dependencies

Hi,
I’ve got a proxmox node and several vm’s running on it. All of this monitored by LNMS. I’ve set up the proxmox node as a parent for each vm in LNMS settings, yet when I reboot the node, I get an alert for the node reboot, and then an alert for each vm regardless. I would’ve thought none of the “children” would alert if “parent” rebooted.

Am I understanding the Device Dependencies wrong, and if so what are they for?

Thanks for any advice!
