Remote Debugging in Nova

You can use a remote debugger to attach to nova services by specifying the host and port as command line arguments. For example

/usr/local/bin/nova-compute --config-file /etc/nova/nova.conf --remote_debug-host --remote_debug-port 1234

In order to do this you need to have a remote debug server - this wiki describes how to use remote debugging with pycharm. You need a commercial license to do remote debugging with pycharm.

Preparing the server

Start pycharm and create a remote debug runtime configuration. Change the host and port to your IP address and the port you want to use.

Pycharm Remote Debug Configuration

Once you have the configuration done, press the bug to start the debugger

Start the debugger

You should see the debugger waiting for connection

Preparing the client

First you need to copy the pydev client script to the environment where you are running nova services.
