--- fixes: - Prior to Mitaka, name resolution in instances requires specifying DNS resolvers via the 'dnsmasq_dns_servers' option in the DHCP agent configuration file or via neutron subnet options. In this case, the data plane must provide connectivity between instances and upstream DNS resolvers. Omitting both of these methods causes the dnsmasq service to offer the IP address on which it resides to instances for name resolution. However, the static dnsmasq '--no-resolv' process argument prevents name resolution via dnsmasq, leaving instances without name resolution. Mitaka introduces the 'dnsmasq_local_resolv' option, default value False to preserve backward-compatibility, that enables the dnsmasq service to provide name resolution for instances via DNS resolvers on the host running the DHCP agent. In this case, the data plane must provide connectivity between the host and upstream DNS resolvers rather than between the instances and upstream DNS resolvers. Specifying DNS resolvers via the 'dnsmasq_dns_servers' option in the DHCP agent configuration overrides the 'dnsmasq_local_resolv' option for all subnets using the DHCP agent.
