Our QA has run the same testcase with grizzly(master branch on github)
more than 20 times, this bug doesn't emerge, so I close it now, and if
this bug reappears later in grizzly with more fully tests, I will reopen
it.

** Changed in: nova
       Status: Incomplete => Fix Released

  AssertionError: after reverting, the flavor of server a658f85e-8430-4889-8339-bf4cabe639ef not changed to 12 (it is 8)

  It seems like revert to a wrong flavor, this issue occurs at least two
  times with this case, but it's a probabilistic issue.
