fb2025ede9 libvirt-guests.service: Add Requires=libvirtd.service
Having After=libvirtd.service merely ensures that, if both
services are asked to start, libvirtd.service will start
first.

What we really want is for libvirtd.service to be started
whenever libvirt-guests.service is asked to start. Adding a
Requires= relationship guarantees that will happen.

7fbe9fa575 libvirt-guests.service: Split After= relationship
We use a separate line for each After= relationship in other
unit files: do the same here for consistency's sake, and also
to make future changes nicer to diff

f4bbbe35f3 libvirt-guests.service: Improve description
libvirt-guests.service does both suspend *and* resume guests,
depending on whether it's being started or stopped: the
description should reflect this, to avoid confusing messages
during startup.

Replace "active" with "running" (to match virsh list's output)
and don't capitalize libvirt.

ba08d16d6c libvirt-guests: Disable shutdown timeout
Since we can't know at service start how many VMs will be running we
can't calculate an apropriate shutdown timeout. So instead of killing
off the service just let it use it's own internal timeout mechanism.

a9bad1a337 libvirt-guests: run after time-sync.target
When libvirt-guests is configured to start guests on host
boot, it is possible for guests start and read the host
clock before it is synchronized.  Services such as
libvirt-guests that require correct time should use the
Special Passive System Unit time-sync.target

1b9f5aa7fe Add Documentation fields to systemd service files
We point to the manpages where available and redirect to libvirt's
homepage as a last resort.

3c9e40a1e8 Don't depend on syslog.service
Syslog is socket activated since at least systemd v35 so we can drop
this dependency. Debian's linitian otherwise complains about it.

d13155c20c tools: Only install guests init script if --with-init=script=redhat
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

c18dc28b1f output status information during guest shutdown again
Since the move to systemd libvirt-guests doesn't output this progress
information anymore. This patch brings back this feature.

It is helpful to show the admin what the system is waiting for and what
is left of the timeout (e.g. for calibrating the shutdown timing of a ups).

Rewriting the current line with \r doesn't work anymore in the context
of systemd. So always write new lines, but move to 5 second intervals
to avoid flooding the console.

79ca7e4e57 libvirt-guests: systemd host shutdown does not work
I originally postet this into the Fedora bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=843836

Currently gracefully shutting down guest vms on host shutdown does not work on
Fedora 17, the guests are killed hard on system shutdown.

The reason is systemd considers libvirt-guests.service to be stopped when the
system is running:

$ systemctl status libvirt-guests.service
libvirt-guests.service - Suspend Active Libvirt Guests
          Loaded: loaded (/usr/lib/systemd/system/libvirt-guests.service;
enabled)
          Active: deactivating (stop) since Fri, 27 Jul 2012 15:47:31 +0200;
2min 48s ago
         Process: 1085 ExecStart=/etc/init.d/libvirt-guests start
(code=exited, status=0/SUCCESS)
         Control: 1150 (libvirt-guests)
          CGroup: name=systemd:/system/libvirt-guests.service
                  └ control
                    ├ 1150 /bin/sh /etc/init.d/libvirt-guests stop
                    └ 2257 sleep 1

libvirt-guests.service is defined as type "simple" in systemd (the default).
That means systemd will shut down the service when the start executable is
terminated after starting is done. Systemd will not call stop again on system
shutdown because it thinks it is already stopped.

The solution is to define it as type "oneshot" and set the flag
"RemainAfterExit". Then systemd will consider the service as active after
startup and will call the stop function on host shutdown.

4789fb2e4e Add support for systemd init service
This patch adds support for a systemd init service for libvirtd
and libvirt-guests. The libvirtd.service is *not* written to use
socket activation, since we want libvirtd to start on boot so it
can do guest auto-start.

The libvirt-guests.service is pretty lame, just exec'ing the
original init script for now. Ideally we would factor out the
functionality, into some shared tool.

Instead of

  ./configure --with-init-script=redhat

You can now do

  ./configure --with-init-script=systemd

Or better still:

  ./configure --with-init-script=systemd+redhat

We can also now support install of the upstart init script

* configure.ac: Add systemd, and systemd+redhat options to
  --with-init-script option
* daemon/Makefile.am: Install systemd services
* daemon/libvirtd.sysconf: Add note about unused env variable
  with systemd
* daemon/libvirtd.service.in: libvirtd systemd service unit
* libvirt.spec.in: Add scripts to installing systemd services
  and migrating from legacy init scripts
* tools/Makefile.am: Install systemd services
* tools/libvirt-guests.init.sh: Rename to tools/libvirt-guests.init.in
* tools/libvirt-guests.service.in: systemd service unit
