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.
