6f4a0ebe8c Configuring systemd to restart libvirt on failure
This will create a respawn behaviour in case libvirt
process exits due to nonzero exit code, is terminated
by a signal, an operation times out or the configured
watchdog timeout is triggered.

443ec5c8c3 libvirt does not logout of iscsi targets, causing system hang on shutdown
There's a quite old bug entry here:

https://bugzilla.redhat.com/show_bug.cgi?id=700010

I just stumbled over that very issue on F18. Doing a little bit
debugging of the shutdown sequence, it turns out that - at least on my
F18 installation - libvirtd is shutdown *after* iscsid, which makes it
impossible for libvirt to perform the logout of the iscsi session properly.

This patch simply adds another startup dependancy on iscsid.service
which in turn delays iscsid shutdown until after libvirtd has stopped.
Having that applied, the system shuts down properly again.

c748037f2a systemd: require dbus service
https://bugzilla.redhat.com/show_bug.cgi?id=830201

The initscript and upstart services depend on dbus starting
before libvirtd.  When we first wrote the systemd script, we
tried to do the same, but we depended on dbus.target (which
does not exist) in comparison to network.target (which does
exist), so we removed that in commit 4c7973e.  But we still
need dbus up and running first, especially now that we want
to support shutdown inhibition via dbus (whereas we originally
needed dbus only for firewall control).

http://www.freedesktop.org/software/systemd/man/systemd.target.html
explains how a target (such as network.target) is just a collection
of common services bundled together, and why we want network.target
but dbus.service.

* daemon/libvirtd.service.in (Unit): Depend on dbus starting
first.

4036aa91bf systemd: start libvirtd after network
Domains configured with autostart may fail to start if the host
network stack has not been started.  E.g. when using bridged
networking autostarting a domain can fail with

libvirtd[1403]: 2012-06-20 13:23:49.833+0000: 1485: error :
qemuAutostartDomain:177 : Failed to autostart VM 'test': Cannot get
interface MTU on 'br0': No such device

4c7973e184 Remove more bogus systemd service dependencies
Adding syslog.target is obsolete, avahi.target does not
exist and dbus.target is also obsolete

6cfc3f8f4f Remove bogus udev.target dep from libvirtd unit
There is no 'udev.target' unit in systemd (only 'udev.service')
yet libvirtd's unit file had a dep on one. There's no compelling
reason for a dep on udev, so remove it altogether.

cb640543c8 Leave all child processes running when stopping systemd service
Currently the libvirt.service unit file for systemd does not
specify any kill mode. So systemd kills off every process
inside its cgroup. ie all dnsmasq processes, all virtual
machines. This obviously not what we want. Set KillMode=process
so that it only kills the top level process of libvirtd

* daemon/libvirtd.service.in: Add KillMode=process

d7320e799f daemon: Allow overriding NOFILES ulimit for the daemon as well
One of my latest patches (d8db0f9690) created support for setting
the limit for the maximum of opened files by qemu user. However,
since libvirtd keeps one FD opened per domain (well, for qemu at least)
it will likely hit this limit on huge scenarios.

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
