I am new to open source and OpenStack so I apologize if my questions does not make sense.

Instead of using apt-get install cinder-api cinder-scheduler I am trying to install Cinder directly from the source code in develop mode using python setup.py develop or pip install -e /root/testCinder I am using Ubuntu Server 16.04 and I cloned the cinder code from https://github.com/openstack/cinder.git to /root/testCinder. I am aware of the Virtualenv, but I need to modify Cinder in a full integration environment. I have below questions:

1. I was wondering what is the best practice to setup up such a development environment that allows rapid modifications and integrated with git as well.
2. If the pip installation successfully finish, does it create the daemon services (cinder-api and cinder-scheduler) or they need to be registered manually ?
3. In general, is there any documentation to describe how to manually install OpenStack components?

Below is the STDERR output for pip install -e /root/testCinder/cinder/ 2> pip_stderr.txt :
