Hello,

how is it possible to inject another search domain as openstacklocal in the resolv.conf of a VM. We use Newton with neutron.

Or use cloud-init. Open http://cloudinit.readthedocs.io/en/la... and scroll down to Configure an instances resolv.conf.

Of course, the image must have cloud-init enabled. Note that Cirros doesn't, but you can inject shell scripts into Cirros instances.

I just had the same problem and I found a quick&dirty solution:

Just edit the /etc/neutron/dnsmasq-neutron.conf file and add at the bottom

domain=yourdomain.example.com

and then, restart the dhcp-agent by executing:

systemctl restart neutron-dhcp-agent

From now on, your instances should be getting that search domain on new dhcp requests.

I also tried the "dns_domain =" option on /etc/neutron/neutron.conf but it does not work. If some neutron guru has a more "openstack"-y solution, that would be great.
