Fairly; I was able to reproduce the mismatch even without designate; specifically:
/etc/neutron/plugins/ml2/ml2_conf.ini [ml2] extension_drivers = port_security,dns_domain_ports /etc/neutron/neutron.conf [DEFAULT] dns_domain = jamespage.example. I then updated the dns_domain on the private network: openstack network set private --dns-domain designate.example. and booted a couple of instances: $ dnsmasq --no-hosts --pid-file=/opt/stack/data/neutron/dhcp/e2637497-2ed8-4a08-9cca-9b2cd86accd1/pid --dhcp-hostsfile=/opt/stack/data/neutron/dhcp/e2637497-2ed8-4a08-9cca-9b2cd86accd1/host --addn-hosts=/opt/stack/data/neutron/dhcp/e2637497-2ed8-4a08-9cca-9b2cd86accd1/addn_hosts --dhcp-optsfile=/opt/stack/data/neutron/dhcp/e2637497-2ed8-4a08-9cca-9b2cd86accd1/opts --dhcp-leasefile=/opt/stack/data/neutron/dhcp/e2637497-2ed8-4a08-9cca-9b2cd86accd1/leases --dhcp-match=set:ipxe,175 --dhcp-userclass=set:ipxe6,iPXE --local-service --bind-interfaces --dhcp-range=set:tag1,10.0.0.0,static,255.255.255.192,86400s --dhcp-option-force=option:mtu,1450 --dhcp-lease-max=64 --conf-file= --domain=designate.example. $ cat /opt/stack/data/neutron/dhcp/e2637497-2ed8-4a08-9cca-9b2cd86accd1/host fa:16:3e:9f:cf:f8,host-10-0-0-1.jamespage.example.,10.0.0.1 fa:16:3e:c3:0e:f7,host-10-0-0-2.jamespage.example.,10.0.0.2 fa:16:3e:4d:fc:2f,testserver-1.jamespage.example.,10.0.0.10 fa:16:3e:41:f8:61,testserver-2.jamespage.example.,10.0.0.32 you can clearly see that the entries in the host file are based on the configured jamespage.example. but that the domain is set to designate.example. as configured on the network. This generates the forward/reverse DNS lookup mismatch from an instance perspective. The dns_assignment of one of the servers ports looks like: | dns_assignment | fqdn='testserver-1.jamespage.example.', hostname='testserver-1', ip_address='10.0.0.10' | this is used to populate the dnsmasq host file. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1826419 Title: dhcp agent configured with mismatching domain and host entries To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1826419/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
