Look at instance migration branch ComputeService table. How about json text field network-info. We want to do qdr infiniban ifs also.

It's been proposed that we don't need to track the mac address(es) but I think it's necessary in order to determine whether a mac is unique or not. Mac addresses don't need to be unique across a whole implementation but they do need to be unique as far as layer 2 networking is concerned. It will be quite a while before we run out of mac addresses across the whole implementation so allowing duplicate macs but preventing duplicates within a network layer two "zone" (not sure the terminology at this point) can be handled later. I propose making a new table for storing instance id mac address relationships. I'm also considering randomly generating mac addresses using instance uuid as salt.
