What happens if you stop and start the service (not reload or 
restart) after starting Xen and any guests ?
If it's still the same then I'd say you need to look at the config - 
does the OS have a file for declaring startup options ?
I don't think this is anything to do with ACLs in your BIND config - 
if (for example) you specify an "allow-query" clause, that doesn't 
control which interfaces/IPs the service will listen on.
If stopping/starting the service brings it up on all interfaces/IPs, 
then perhaps something isn't ready at the time BIND starts.
