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.

# 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?
