Hi, The metadata service is only accessible from within VM. Did the VM get IP address from DHCP server? Where did you run the curl command? Do you have access to the VM? My suggestions: 1. check whether the instance get IP correctly and can connect to nova and neutron node. 2. check whether neutron-metadata-agent is running. 3. check neutron-metadata-agent log for errors. 4. check whether iptables rules for metadata service is effective in virtual network namespace. -- *YY Inc. is hiring openstack and python developers.
