Okay, so the problem there is that the hostname doesn't resolve. To anything. It's traditionally not the best form to be putting the hostname in the 127.0.0.1 line of /etc/hosts but you can do that:
...
127.0.0.1 xenserver-isin00 localhost.localdomain localhost isin09
...
Should get you around the exception.
