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.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
