Hi Stackers-

With respect to the current implementation of Nova-Compute,
We are able to send the Compute Node Registration and other notifications with only "Hostname" of the Compute Node.

Also, in the Nova database, We are also maintaining the Hostname rather than the IP address of the node.

I have the following doubts with respect to the Hostname

[1] How would duplicate hostnames be handled ?
[2] How to know the IP address of the Compute Node, in the existing implementation ?

In the definition, update_service_capabilities(), it takes a dict() with host_ip as key with my_ip(gathered from nova.conf) as its value.

I haven't seen any place where this host_ip is stored into Nova DB.

Kindly help me understand and resolve the same.
