Every now and then a 'xend start' does nothing and sends no output to console. Commands such as 'xm list' will give a 'Connection refused' error. A 'xend stop' followed by a 'xend start' usually fixes this but there have been a few times where I have had to repeat the cycle a couple of times. Also, sometimes after a reboot, a domain creation just fails and the 'xm create' command does not return. There are no error messages from xend. Even though I suspect that things are hosed at this point in time, a 'xend stop' works. However xend will not startup again and gives a 'IOError: [Errno 16] Device or resource busy' error. The problem cannot be reproduced as the same create command works after another reboot.
