Found a py3 compatibility-related TODO in vstart_runner.py's clear_old_log() -

    from os import stat

    try:
        stat(logpath)
    # would need an update when making this py3 compatible. Use FileNotFound
    # instead.
    except OSError:
        return
    else:
        os.remove(logpath)
        with open(logpath, 'w') as logfile:
            logfile.write('')
        init_log()
        log.debug('logging in a fresh file now...')
