<p>Hi Brian,</p>
<p>The lease does have the two Google nameservers in it, however a
new VM is still somehow getting the old values as well. That is
what is confusing me. If it helps we are using Queens still
currently.</p>
<p>Is there any database entry that I can change? <br>
</p>
<p>Many thanks for your help.</p>

We have a bit of a weird issue with resolv.conf for instances.
We have changed our subnets in neutron to use googles
nameservers which is fine. However it seems that when instances
are launched they are still getting the old nameserver settings
as well as the new ones. If I look at the metadata networking
service it returns the old nameservers as well as the new ones
below:
<br>
<br>
curl -i
<a class="moz-txt-link-freetext" href="http://169.254.169.254/openstack/2017-02-22/network_data.json">http://169.254.169.254/openstack/2017-02-22/network_data.json</a>

{"services": [{"type": "dns", "address": "178.18.121.70"},
{"type": "dns", "address": "178.18.121.78"}, {"type": "dns",
"address": "8.8.8.8"}, {"type": "dns", "address": "8.8.4.4"}]
<br>
<br>
In our neutron dhcp-agent.ini file we have the correct dnsmasq
nameservers set:
<br>
<br>
dnsmasq_dns_servers = 8.8.8.8, 8.8.4.4
<br>
<br>
Are there any database tables I can change or clear up to ensure
the old nameservers no longer get set? I can't seem to find any
reference in our config any more of the old nameservers, so I
assume one of the services is still setting them but I can't
figure out what is.

<br>
So does the DHCP response on lease renewal just have the two
Google nameservers in it? If so, does a new VM booted on the
subnet have the correct metadata values reported? Just trying to
narrow-down if this is in the neutron code or not.
