Can you elaborate on what you mean here? What are the issues with port<br>
creation?<br>

Having nova-compute create ports for neutron is problematic if timeouts occur between nova and neutron as you have to garbage collect neutron ports in nova to cleanup (which was the cause of several bug in the cache handing allowing ports to leak into the info_cache
in nova). Pushing this out to the tenant is less orchestration nova has to do. </div>

<div>[gary] my take on this is that we should allocate this via the n-api and not via the nova compute (which is far too late in the process. But that is another discussion :)</div>
