Right now, libvirt-guests gives awkward output. It's possible to
force faster failure by setting /etc/sysconfig/libvirt-guests to use:
ON_SHUTDOWN=shutdown
PARALLEL_SHUTDOWN=0
SHUTDOWN_TIMEOUT=1
ON_BOOT=ignore
at which point, we see:
$ service libvirt-guests restart
Running guests on default URI: a, b, d, c
Shutting down guests on default URI...
Starting shutdown on guest: a
Shutdown of guest a failed to complete in time.Starting shutdown on guest: b
Shutdown of guest b failed to complete in time.Starting shutdown on guest: d
Shutdown of guest d failed to complete in time.Starting shutdown on guest: c
Shutdown of guest c failed to complete in time.libvirt-guests is configured not to start any guests on boot
* tools/libvirt-guests.sh.in (shutdown_guest): Add missing newline.
Reported by Xuesong Zhang.
Most of this deals with moving the libvirt-guests.sh script which
does all the work to /usr/libexec, so it can be shared by both
systemd and traditional init. Previously systemd depended on
the script being in /etc/init.d
