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

[Alexander Groleau]

I have tried the following script as well during my adventures with no
success:

[Unit]
Description=Start/Stop Libvirt Windows Guest
Documentation=man:libvirtd(8)
Documentation=http://libvirt.org
After=libvirtd.service

[Service]
ExecStart=/usr/bin/libvirt-windows.sh start
ExecStop=/usr/bin/libvirt-windows.sh stop
RemainAfterExit=yes
Type=oneshot
StandardOutput=journal+console

[Install]
WantedBy=multi-user.target

This works for boot (my sh script is run right after libvirtd is started);
however, the libvirtd daemon, started by libvirtd.service, is always
terminated well before my sh is run on shutdown/reboot. The reverse order
is not happening as it logically should. I will post the journal for this
script shortly.

So, still no luck :/

Thanks,
Alex
