Title:
  Nova Network crash when instances are created

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  Using fedora 19 Schrodïnger's Cat and OpenStack Grizzly (2013.1.3) has
  a host for nova-compute / nova-network, it is impossible to use nova-
  network has network manager.

  AMQP Broker is Qpidd C++ Broker

  As reported to this topic on ask.openstack.org and
  openstack.redhat.com:

  https://ask.openstack.org/en/question/5288/nova-network-is-crashing-
  hard/

  http://openstack.redhat.com/forum/discussion/560/launch-instance-
  error-with-fedora-19-image-in-openstack-grizzly/p1?post#Form_Body

  Nova-Network seems to use a bad formatted message which result in a
  crash exception on SQLAlchemy 0.8.2 used by Fedora 19.

  Here is the error message we receive when we try to create a new
  instance:

  http://paste.openstack.org/show/n3XI87B6Ss8s94C85VqL/

  has we can read it from the python stack from line 49 to 55 SQLAlchemy
  seems to receive a bad formatted message from the
  nova.openstack.common.rpc.common.amqp module.

  So it seems that Nova Network is incorrectly formatting its messages.
  This can't be a qpid missconfiguration as any other services (Glance/Cinder) are able to communicate and create volumes and images correctly, plus, if we disable network module, OS is able to create correctly the instances without network so RPC are passing through AMQP correctly.

  Here is the Nova.conf file use:

  http://paste.openstack.org/show/nQyKLdxGjkb4VEgik5dv/

  Our Compute node is the CLUNODE02 here, and here is its IP
  Configuration:

  Here is the result of a nova-manage network list:

  http://paste.openstack.org/show/Vn7WoLtBLDI0oWGOLZ3D/

  As indicate on the question on ask Q&A Website, we cannot perform a
  SQLAlchemy regression on FE19 due to OS Dependencies which then are
  broken.
