Title:
  Using SSL with rabbitmq prevents communication between nova-compute
  and conductor after latest nova updates

Status in OpenStack Compute (nova):
  New
Status in oslo.messaging:
  New

Bug description:
  On the latest update of the Ubuntu OpenStack packages, it was
  discovered that the nova-compute/nova-conductor
  (1:2014.1.4-0ubuntu2.1) packages encountered a bug with using SSL to
  connect to rabbitmq.

  When this problem occurs, the compute node cannot connect to the
  controller, and this message is constantly displayed:

  WARNING nova.conductor.api [req-4022395c-9501-47cf-bf8e-476e1cc58772
  None None] Timed out waiting for nova-conductor. Is it running? Or did
  this service start before nova-conductor?

  Investigation revealed that having rabbitmq configured with SSL was
  the root cause of this problem.  This seems to have been introduced
  with the current version of the nova packages.   Rabbitmq was not
  updated as part of this distribution update, but the messaging library
  (python-oslo.messaging 1.3.0-0ubuntu1.1) was updated.   So the problem
  could exist in any of these components.

  Versions installed:
  Openstack version: Icehouse
  Ubuntu 14.04.2 LTS
  nova-conductor    1:2014.1.4-0ubuntu2.1
  nova-compute        1:2014.1.4-0ubuntu2.1
  rabbitmq-server  3.2.4-1
  openssl:amd64/trusty-security   1.0.1f-1ubuntu2.15
