+The basic idea of the test is that there are a number of actions, roughly

 corresponding to the Compute API, that are fired pseudo-randomly at a nova 

 cluster as fast as possible. These actions consist of what to do, how to

 verify success, and a state filter to make sure that the operation makes sense.

 For example, if the action is to reboot a server and none are active, nothing

 should be done. A test case is a set of actions to be performed and the
