RAMCloud doesn't work properly

[Li Ma]

Reproducing:

1. Using the latest devstack and dragonflow with the default local.conf for RAMCloud.

2. Run stack.sh.

3. df-local-controller doesn't work and it shows:
2015-12-16 11:58:52.500 WARNING dragonflow.controller.df_local_controller [-] run_db_poll - suppressing exception
2015-12-16 11:58:52.501 WARNING dragonflow.controller.df_local_controller [-]

4. In run_db_poll, I import traceback to see what happens:
2015-12-16 12:05:45.112 WARNING dragonflow.controller.df_local_controller [-] Traceback (most recent call last):

It would be very helpful if you will also attach the stack log.

Run stack.sh again for a flesh installation. Everything goes well. I cannot reproduce this bug. I have no idea about it.
