Hi.<br class="gmail_msg">
<br class="gmail_msg">
I'm facing a problem related to dns_name and dnsmasq.<br class="gmail_msg">
<br class="gmail_msg">
Nova and Neutron can create a port with dns_name and dnsmasq it's correctly updating "/addn_host".<br class="gmail_msg">
<br class="gmail_msg">
The problem is when Nova boot an instance using a new or previusly created port. The port has the correct dns_name but dnsmaq (dhcp_agent) it's using the generic (ex. host-10-0-0-16) names.<br class="gmail_msg">
<br class="gmail_msg">
If I restart dhcp_agent or do a port-update on the port, the correct name is added to addn_host.<br class="gmail_msg">
<br class="gmail_msg">
Any ideas?<br class="gmail_msg"></div></div>

<br class="gmail_msg">
Probably a bug in Mitaka where Neutron controller does not notify DHCP agent about an update. I think it should be solved in Newton with <a href="https://review.openstack.org/#/c/355117/" rel="noreferrer" class="gmail_msg" target="_blank">https://review.openstack.org/#/c/355117/</a> and <a href="https://review.openstack.org/#/c/375189/" rel="noreferrer" class="gmail_msg" target="_blank">https://review.openstack.org/#/c/375189/</a> plus other related patches that belong to push-notifications blueprint.<br class="gmail_msg">
<br class="gmail_msg">
Note that those patches are not safe to backport back to Mitaka, so if we get a bug reported against Mitaka for the behaviour you describe, we may need to solve it in some other way.<br class="gmail_msg">
