Description of problem: When XenD opens its debug log file /var/log/xend-debug.log it only specifies O_WRONLY | O_CREAT for its open mode. This means that it starts writing new log messages at the beginning of the log file, rather than the end. So the log file gets a whole mix of log messages in non-sequential order, making it essentially useless. The fix is to use either O_APPEND or O_TRUNC when opening the log file. Version-Release number of selected component (if applicable): xen-3.0.3-2.el5 How reproducible: Always Steps to Reproduce: 1. Start xend 2. Start a guest domain 3. Examine contents of /var/log/xen/xend-debug.log 4. Shutdown guest 5. Restart xend 6. Start guest again 7. Look at xend-debug.log again Actual results: New messages are before old messages in the log file Expected results: Log messages are sequentially ordered Additional info:
