What's the output of rackd.conf vs regiond.conf ?

If rackd.conf points to localhost and regiond.conf points to a different IP address, then the metadata url will be the one of regiond.conf. To properly configure this, you need to change rackd.conf to point to an IP address.

That said, the metadata url always has to be an IP that's accessible to the machines so that the machines can always get their metadata. For example, if you pxe boot multiple vlans on the same rack controller (which is typically not reocmmended) the URL of the metadata needs to be one accessible from the various VLANs, and this is because you typically dont have the rack controller in the same VLAN.
