    main()

However, it is shown to not exist in the output

Traceback (most recent call last):
  File "C:/Users/rafranci/Downloads/ovirt_st_setup.py", line 20, in <module>
    class InstallTest():
  File "C:/Users/rafranci/Downloads/ovirt_st_setup.py", line 65, in InstallTest
    main()
  File "C:/Users/rafranci/Downloads/ovirt_st_setup.py", line 63, in main
    lago()
NameError: name 'lago' is not defined

As far as I can see, there is no reason for this – ideas?

    You have to instantiate class to call its method.

    def main():
   InstallTest().lago()

    or

    def main():
   install_test = InstallTest()
   install_test.lago()

    This will work only if you are adding self parameter in your class.

    def lago(self):
    """run the conductor profiles required to install OLVM """
    Log.test_objective('TODO')
    run_command_checking_exit_code('ls -al')

    Also, I don’t understand why you needed class for this. If you don’t have any reason you can just remove the class and then your previous code will work fine as suggested in the comments.
