Hi, Here is an easy bug to fix for a newcomer to cloudstack:
https://issues.apache.org/jira/browse/CLOUDSTACK-3096 install pep8 on your machine git clone cloudstack repo go to the marvin directory run pep8 like I show in the bug. edit the python scripts to fix the errors once pep8 is clean, git commit everything, create a patch and send to review board. Any takers ? -Sebastien
