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

[Unit]
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.

Description=Suspend/Resume Running libvirt Guests
libvirt-guests: Weaken dependency on libvirtd The Requires relationship is very strong, in that it prevents a unit from running unless all the units it Requires are running as well. This turns out to be a problem because we want to be able to restart libvirtd at any time without having libvirt-guests suspend or shutdown running guests. Turn the Requires relationship into a Wants relationship: this way starting libvirt-guests will cause systemd to (attempt to) start libvirtd as well, but stopping or restarting libvirtd will not alter libvirt-guests' running state.

libvirtd: systemd: add special target for system shutdown It is already discussed in "[RFC] daemon: remove hardcode dep on libvirt-guests" [1]. Mgmt can use means to save/restore domains on system shutdown/boot other than libvirt-guests.service. Thus we need to specify appropriate ordering dependency between libvirtd, domains and save/restore service. This patch takes approach suggested in RFC and introduces a systemd target, so that ordering can be built next way: libvirtd -> domain -> virt-guest-shutdown.target -> save-restore.service. This way domains are decoupled from specific shutdown service via intermediate target. [1] https://www.redhat.com/archives/libvir-list/2016-September/msg01353.html

# Hack just call traditional service until we factor
# out the code
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 Required to fix https://bugzilla.redhat.com/show_bug.cgi?id=789747

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.

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.

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. References: http://bugs.debian.org/803714 https://bugzilla.redhat.com/show_bug.cgi?id=1195544
