# Init script for libvirtd on Slackware
# Written by Matteo Bernardini <ponce@slackbuilds.org>
#
# Note that a dnsmasq daemon is started by libvirtd itself to serve
# its virtual network, and possibly can conflict with a dnsmasq
# already running on the system, see
# http://wiki.libvirt.org/page/Libvirtd_and_dnsmasq
# Note also that the tun, vhost_net and kvm related modules are
# automatically loaded at start and removed at stop: edit the
# script if this behaviour conflicts with anything else running
# on your setup
