It can be executed as follows: .. code-block:: bash git clone https://gerrit.opnfv.org/gerrit/doctor -b stable/colorado cd doctor/tests CONSUMER_PORT=12346 python consumer.py "$CONSUMER_PORT" > consumer.log 2>&1 & Consistent resource state awareness ----------------------------------- Resource state of compute host can be changed/updated according to a trigger from a monitor running outside of OpenStack Compute (Nova) by using force-down API. See http://artifacts.opnfv.org/doctor/colorado/manuals/mark-host-down_manual.html for more detail. Valid compute host status given to VM owner ------------------------------------------- The resource state of a compute host can be retrieved by a user with the OpenStack Compute (Nova) servers API.
