libvirt-guests.service doesn't work, but manually running libvirt-guests.sh stop does

[james harvey <jamespharvey20@xxxxxxxxx>]

Using libvirt 1.2.18 (-1 Arch) and QEMU git-master (2.4.0.r40384.2d69736).  pm-utils 1.4.1-6.  acpid 2.0.23-4

Installed using Q35 chipset.

I can perform virsh # shutdown <vmname>, and watching the client VM console see a graceful shutdown.

On host:
=====

# systemctl reboot

{{{ client VM console immediately blanks out - I do NOT see a graceful shutdown }}}
libvirt-guests.sh: Running guests on default URI: <vmname>
libvirt-guests.sh: Shuitting down guests on default URI...
libvirt-guests.sh: Starting shutdown on guest: <vmname>
libvirt-guests.sh: Waiting for 1 guests to shut down, 300 seconds left
A stop job is running for Suspend Active Libvirt Guests... libvirt-guests.sh: Waiting for 1 guests to shut down
=====
In about 85 seconds, it moves past this, but guest was not suspended or gracefully shutdown.  Guest's "last" shows a crash.  And, watching on the VM console, the minute systemctl restart runs on the host, the VM console disconnects.

# systemctl status libvirt-guests

A virsh # shutdown <vmname> or an in-guest systemctl poweroff takes a few seconds (3-5?)

Strangely, manually running "/usr/lib/libvirt/libvirt-guests.sh stop" lets me see a graceful shutdown on the VM console and shows (executing in a few seconds):

Running guests on default URI: <vmname>
Shutting down guests on default URI...
Starting shutdown on guest: <vmname>
Waiting for 1 guests to shut down, 300 seconds left
Shutdown of guest <vmname> complete.
