Folks,

For the experiment, I am deploying epoxy in the lab and getting some nova related issues. not sure if they are bugs or just config tuning. 

#BUG 1 

placement_api container failed to start because of uWSIG provider issue. I have changed to apache that fixed the issue. 

placement_api_backend: "apache"
placement_wsgi_provider: "apache"

# BUG 2 or Failed it this point. 

TASK [nova-cell : Waiting for nova-compute services to register themselves] ******************************************************************************************************************************************
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
fatal: [vsan2]: FAILED! => {"msg": "Unexpected failure during module execution: Expecting value: line 1 column 1 (char 0)", "stdout": ""}

# BUG 3

inside the nova-computer container I didn't see any service or process related privsep-helper --config-file /etc/nova/nova.conf is this something new or missed by bug or config?
