# 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
