Metadata is hosted by the nova-api server. When using Neutron, the neutron-metadata-
agent on the network node proxies metadata requests to nova-api. It does a couple
of queries to Neutron,adds the instance-id to the request and forwards the message
to nova-api. This is because when using nova-network you cannot have overlapping IPs
so the nova metadata server can figure out the instance ID from its IP. Neutron
does support overlapping IPs so that's why the neutron-metadata-agent exists.

If curl 169.254.169.254 doesn't work, check for errors in the neutron metadata
agent logs and in nova-api as well.
