Hi As per my IRC chats with dansmith, russellb, this feature needs the user auth checks (being taken care of in https://bugs.launchpad.net/nova/+bug/1221396). Dan has some more comments .... Could we please do a FFE for this one .... has been waiting for a long time and we have done all that we were asked relatively quickly .... in H2 it was gated by API object refactor. Most of the current comments (pre last one by Dan) are due to https://bugs.launchpad.net/nova/+bug/1221396 -- -Debo~
