I have just put up a review here:
which should address the exercise.sh issues when n-cell is enabled. Hopefully this works in the gate like it does for me locally. Then we can move on to looking at tempest.

>>> Like I said, as long as someone is going to work on it, I'm happy. :) I just don't want this to be an enable the tests and hope magically fairies come to fix them issue. That's what we did on full neutron tests, and it's been bouncing around like that for a while.
>>> We are planning on disabling the devstack exercises, it wasn't so much that, it's that it looks like there is fundamental lack of functioning nova on devstack for cells right now. The security groups stack trace is just a side effect of cells falling over in a really low level way (this is what's before and after the trace).

>>> Again, mostly I want to know that we've got a blueprint or bug that's high priority and someone's working on it. It did take a while to get grenade there (we're 2 bugs away from being able to do it repeatably in the gate), but during that time we did have people working on it. It just takes a while to get to the bottom of these issues some times, so I want people to have a realistic expectation on how quickly we'll go from running upstream to gating.
