Comment 6 for bug 1473483

Reproduced on MOS 7.0 ISO #295

Add section

dhcp-range=alpha,10.109.1.68,10.109.1.127,255.255.255.0,120m
dhcp-option=net:alpha,option:router,10.109.1.65
dhcp-boot=net:alpha,pxelinux.0,boothost,10.109.1.2

into dnsmasq.template

dockerctl shell cobbler vi /etc/cobbler/dnsmasq.template

reboot

Section disappears :)

Notes

1 There is cool script for converting dnsmasq.template but it is can be used only during rpm upgrade
2 There is support for additional parameters extra_admin_net but there is no reference or example in

https://docs.mirantis.com/openstack/fuel/fuel-master/file-ref.html#dnsmasq-template-ref
and
https://docs.mirantis.com/openstack/fuel/fuel-6.1/file-ref.html#astute-yaml-master-ref

about second doc was created bug https://bugs.launchpad.net/fuel/+bug/1496884
