Open Stack

Hi,

just one more thing to check: whenever I had troubles with the  
metadata it was usually apparmor blocking the access. For testing  
purposes (or if you're behind a firewall anyway) you could try to  
disable all the security related daemons and see if that helps. If you  
don't have it enabled, do you see any errors in the neutron logs?
