Code review comment for lp://qastaging/~klmitch/nova/os_int_tests

Alright, if you are planning on doing tests against live clusters, perhaps then look at the smoketests directory. I don't like the name of it but it is doing exactly that. I think we'd probably love to get your tests in alongside those then, as the existing ones are only really testing the ec2 api.

Regarding DTest, it looks nice and we certainly want parallelization of tests, but we also are pretty happy with most of what nose gets us, what do you think the options are for integration with nose are?
