Evan,

Where are you pinging from? Displaying the ifconfig -a output on all nodes
could be useful.

I tried installing it on the cloud controller and configuring the metadata_host on the quantum gateway to point to it. I still can't ping 169.254.169.254 from anywhere. Should that go on the quantum gateway itself instead?
