  * https://www.linux.com/learn/intro-to-linux/2018/2/advanced-dnsmasq-tips-and-tricks

====== Troubleshooting ======
===== - DNSMASQ =====

    # dnsmasq --no-daemon --log-queries --log-facility=/var/log/dnsmasq.log

===== - IPTABLES =====
On fedora 28 iptable seem to prevent dhcp request to reach dnsmasq.

    iptables -F

Add rules:
    sudo /sbin/iptables -A INPUT -p udp --dport 53 -j ACCEPT
    sudo /sbin/iptables -A INPUT -p tcp --dport 53 -j ACCEPT

Recreate network (TODO test this):    
    sudo ansible-playbook -i inventory/vi_nodes quicklab_kvm_openstack.yml --tags network -vvvv
