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

Wow, bunch of nice stuff. I'm a little worried it may be duplication of effort / code however, have you looked in nova/tests/integrated? It is doing much of the same stuff you are doing. It doesn't use DTest but it may be interesting for you to look into porting them to it, or adding your tests alongside them if the overlap in testing is small.
