The log_dir in trove-guestagent.conf.sample currently defaults to '/tmp', and the log_file to 'logfile.txt'. If the log_dir value is changed to, say, '/var/log/trove', guest initialization will fail because the directory does not exist. Even if log_dir is set to '/var/log', initialization will fail due to insufficient write permissions in said directory. Solution: The log_dir specified in trove-guestagent.conf.sample should be created on-demand if necessary. Change-Id: Ic819aaa08f8a78483e1c0ae0aa8af370c6705562 Closes-Bug: #1219137
