Package: libvirt-daemon-system Version: 1.2.9-9+deb8u1 In /etc/default/libvirt-guests the default timeout for guests shutting down or suspending on host shutdown/reboot is 300 seconds. However, systemd has timeouts for service units to stop. The default is 90 seconds, as viewable by: systemctl show libvirt-guests | grep Timeout
We should specify a timeout in the libvirt-guests.service file, ideally take directly the configured timeout from /etc/default/libvirt-guests . As workaround, I created a systemd drop-in file: /etc/systemd/system/libvirt-guests.service.d/local-timeout.conf: [Service] TimeoutStopSec=300 The bug was already reported to Fedora, see https://bugzilla.redhat.com/show_bug.cgi?id=1195544 for further details and consequences.
