Doc Text: |
This version introduces support for internal DNS resolution in networking-ovn. Although there are two know limitations,
one is bz#1581332 which prevents proper resolution of internal fqdn requests via internal dns.
Please note that the extension is not configured by default by tripleo on the GA release. See bz#1577592 for a workaround.

Some examples of how to configure it at OVN level: https://github.com/openvswitch/ovs/blob/adabd65ddd8217cf1a27f654136ff74d4fd544bf/tests/ovn.at#L6598 As per @numans explanation, this feature works by capturing any DNS request, and responding locally on OVN controller if we have an answer, otherwise the packet is released back to the openflow pipeline and will reach the normal DNS server if that was configured via DHCP. One thing that we could have here missing compared to neutron is the ability to do inverse resolution, but that could be easily added to core-ovn later. https://review.openstack.org/#/c/522215/ is merged It was verified, but two bugs were opened: 1581332 and 1577592 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
