What was excruciating about the subscription process?

Where are you curl'ing from? The compute node or the host running the
nova-ec2-metadata service?

I think you're missing a paste above :) doing something like what?

Well, it's unlikely it's an issue with the metadata service because the
metadata service is clearly responding properly to at least ONE host, as
evidenced above. It's more likely a routing issue.

Can you SSH into the VM in question and try pinging the EC2 metadata
service URL? (http://169.254.169.254:8775/)
