fixes:
|
||||
- |
|
||||
Previously a network's dns_domain attribute was ignored by the DHCP agent.
|
||||
With this release, OpenStack deployments using Neutron's DHCP agent will
|
||||
be able to specify a per network dns_domain and have instances configure
|
||||
that domain in their dns resolver configuration files (Linux's
|
||||
/etc/resolv.conf) to allow for local partial DNS lookups. The per-network
|
||||
dns_domain value will override the DHCP agent's default dns_domain
|
||||
configuration value. Note that it's also possible to update a network's
|
||||
dns_domain, and that new value will be propogated to new instances
|
||||
or when instances renew their DHCP lease. However, existing leases will
|
||||
live on with the old dns_domain value.
