[systemd-devel] Cannot get Shutdown Script to Run (Libvirt Virtual Machine Shutdown)

[Alexander Groleau]

Thanks for the reply :) The libvirt-guests.service was the very first thing
I had tried. It, however, did absolutely nothing and I believe it to be
broken in arch linux. I have given up on trying to get a shutdown/reboot
script to run for now.
