Subject: [openstack-dev] [nova] Static IPAddress configuration in nova.conf file

Nova-compute in Compute nodes send fanout_cast to the scheduler in Controlle Node once every 60 seconds.  Configuration file Nova.conf in Compute Node has to be configured with Management Network IP address and there is no provision to configure Data Network IP address in the configuration file. But if there is any change in the IPAddress for these Management Network Interface and Data Network Interface, then we have to configure them  manually in the configuration file of compute node.
We would like to create BP to address this issue of static configuration of IPAddress for Management Network Interface and Data Network Interface of Compute Node by providing the interface names in the nova.conf file.
So that any change in the ipaddress for these interfaces will be updated dynamically in the fanout_cast  message to the Controller and update the DB.
We came to know that the current deployments are using some scripts to handle this static ipaddress configuration in nova.conf file.
Any comments/suggestions will be useful.
