How does one change the DNS for a network created via nova-network / FlatDHCP without deleting the network (impossible with 20+ VMs)?

Thanks, JMS

The Compute service uses dnsmasq as the DHCP server when running with the Flat DHCP Network Manager.

The behavior of dnsmasq can be customized by creating a dnsmasq configuration file. Specify the config file using the dnsmasq_config_file configuration option.

Add your DNS server in the dnsmasq conf, restart nova-network and it should do what you want.
