# 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
