DNS for instances

Hi all,

I am having a bit of an issue with DNS for instances. We are wanting to 
update our DNS servers that all instances use. I have tested this by 
using google's nameservers for now and set both of our subnets to use 
"8.8.8.8 & 8.8.4.4", I have also changed the "dhcp_agent.ini" on our 
Neutron nodes to have:

dnsmasq_dns_servers = 8.8.8.8, 8.8.4.4

I have restarted the dhcp agents on both nodes, however whenever a new 
instance is launched, it is still using the old DNS server setup.

Is there anything else I need to do or anything I have missed to make 
sure instances use the updated DNS servers?

Many thanks,

Grant
