Hi Erik Thank you for response! Yes, you are absolutely right OpenStack API already support shared IP groups. Suppose there are some misunderstanding, because I wrote about floating IPs.
I want to have API for association IPs from floating IPs pool with particular VM. At this moment we have #1 implementation as a path in our RPM repo http://yum.griddynamics.net/. And going to make the merge proposal to trunk. Also we going to create blueprint about #3 and attach branch to it.
