OpenStack L3 East-West Performance within single compute node
*************************************************************

In this scenario Shaker launches 1 pair of instances, both are hosted on the
same compute node.  Instances are connected to one of 2 tenant networks, which
plugged into single router. The traffic goes from one network to the other (L3
east-west).

**Scenario**:

.. code-block:: yaml

    deployment:
      accommodation:
      - pair
      - double_room
      - compute_nodes: 1
