The metadata service in Folsom will only work when overlapping IP ranges are disabled (see: http://docs.openstack.org/trunk/openstack-network/admin/content/ch_limitations.html).  For Grizzly, we have added metadata service for overlapping networks.  This feature is currently available in devstack when you enable the q-meta service.

Am trying to use Ubuntu UEC image to spawn VMs, but when the VM instance boots, it is not able to contact the metadata server in order to (among other things) inject the public key needed in order for me to be able to SSH into the instance. See http://paste.openstack.org/show/28764/ for a log snippet if needed.

When I dump the iptables rules for the 'nat' table, I see that my added rule is being hit, but it's still not working:
