Usage with libvirt

Network-manager think if there is one running libvirt that he run this before. To fix conflicts between other dnsmasq, eg: used in libvirt, you must run it externally.

We do not want change our resolv.conf automaticly.

/etc/NetworkManager/NetworkManager.conf
[main]
...
dns=none

We put it manually here.

/etc/resolv.conf.head
nameserver 127.0.0.1

The interface to bind and bind it even if there is second dnsmasq runned on computer.

/etc/NetworkManager/dnsmasq.d/bind-interface.conf
interface=lo
bind-interface

This start service if interface is up. This service can start only once before stop which will be initiate by systemd on restart/shutdown.

/etc/NetworkManager/dispatcher.d/10_dnsmasq
#!/bin/sh
if [ -n "$2" ] && [ "$2" = "up" ]; then # $INTERFACE is up
	systemctl start NetworkManager-dnsmasq.service
fi
