Just as Jay said, to find out what's going wrong you have to tail
cinder/nova logs while running tests.
There are two things you should keep an eye on:
1. Behaviour (to be clear, does test scenarios coresponds to what actually

2. Resource utilization (may cause errors because of something went wrong,
going back to log analyzation)
