I have seen a number of ''heisenbugs" with xend. They especially occur
when I stop xend and start it again. 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.
