The daemon-conf test would fail on my system if there was a system libvirtd running. In the course of troubleshooting that problem, I discovered that the daemon-conf script would always fail if run by itself because it found the line: \# that each "PARAMETER = VALUE" line in this file have the parameter which it mistook for a line containing a parameter. I have changed the test to avoid mistaking a line containing \"PARAMETER = VALUE\" for a parameter line. The corrupted config tests turned out to be failing because the test daemon was discovering the pid file from the running daemon and exiting before it processed the test config file. Specifying the pid file for the corrupt config tests in the same way as for the valid config test solved that problem.
