Hi All,

What is the correct way to set an instances DNS search suffix via DHCP, 
currently all instances receive the default openstacklocal  DNS search space.  
We are using OpenStack Newton with Neutron Networking.

Setting dhcp_domain in dhcp_agent.ini will set the value globally for all 
networks, which is of little use as we host many Windows VMs with their own 
domains and DNS servers. Whatever is set as dhcp_domain is passed to Neutron 
DHCP Agent dnsmasq subprocess via a --domain=<DOMAIN> parameter.

With the Neutron DNS extension enabled, you can set the a networks dns_domain 
attribute with "neutron net-update --dns-name", though this attribute appears 
to be ignored by the DHCP server. Can this be used to specify the DNS search 
space, if so how can it be configured? I need to be able to configure this on a 
per network/subnet level.

Regards,
Oisin
