"The host_ip was moved to the database because it was being used already and needed a new home, while I agree with the idea behind this BP, if we store it, make it accessible via REST for admins, I think this is a good time to revisit how we store IP addresses and why we do etc" ~jogo 10/28/2013

Thanks Joe. I think storing host_ip in compute_nodes table is ok as it is an attribute of compute node. Also adding host_ip can increase debug ability for end users. ~jay-lau-513 10/28/2013

@Russell, can you give a help? I have uploaded my patch to Gerrit. But as this bp was not approved yet, so the patch in Gerrit was now marked as "Do not merge". Can you please help approve this? Per my previous append, this bp can help improve the debug ability for end user. Thanks. ~jay-lau-513 11/06/2013

"Jay, sounds reasonable enough, can you update the BP with the relevant docImpact information (http://justwriteclick.com/2013/09/17/openstack-docimpact-flag-walk-through/) then we can approve the BP.

Thanks Joe. OK, I will update commit log and upload a new patch again.

Yeah I would love to see some more information on the API that was added, and the likely nova-client patch, etc.

Seems we do not need to update nova client, as the API part already handle the output well. Thanks. --jay-lau-513
