In this post I’ll show you how to debug devstack (neutron) with pycharm.

  1. Install Pycharm .

  2. Create a new project : openstack

  3. Add a new remote host : Tools -> Deployment -> Configuration

remote_host_1


remote_host_2

NOTE : add /data and /logs to excluded paths

  1. Sync remote with local and download all files from remote VM to your local . In Remote host panel -> download from here.

  2. Configure remote interpreter : Settings (Ctrl+Alt+S) -> Project Interpreter -> add remote

remote_interpreter

  1. Enable Gevent compatible debugging : Settings (Ctrl+Alt+S) -> Python debugger -> check Gevent compatible debugging

  2. Start ./stack.sh on devstack VM
    • go to screen mode , `screen -x
    • go to neutron screen q-svc .
    • kill service Ctrl+A K.
  3. Create a new debug configuration on pycharm : Run -> EditConfiguration -> Python . Set following values
    • Script : \usr\local\bin\neutron-server (you can check the exact location from /opt/stack/logs/stack.sh.log file).
    • Script Parameters : –config-file /etc/neutron/neutron.conf –config-file /etc/neutron/plugins/ml2/ml2_conf.ini
    • Python interpreter: remote interpreter created in above step.

We can debug using remote debugger as well . I’ll check it out and update the post

###Happy Debugging .
