Shotdown VMs in specific order when UPS initiates shutdown of the node

Hello,

i'd like to connect my UPS (APC) to the Proxmox node and manage it with apcupsd via the USB port. Is there a way to configure an automatic shutdown for the VMs in a specific order when the UPS is drained within five minutes and to shutdown the node afterwards.

I'm not running a cluster so far, but it might be interesting to migrate specific VMs to another node when the UPS gets drained. Is that possible?

Does anybody have such a setup?

Regards,
minas

p.s.: Sorry for the typo in the title ;) - should be shutdown, of course. :D
