Did you snip this log?  I would have thought you'd see cloud-init
complaining about lack of data source. (re-trying on the meta-data
source).

Also, in order to debug why there is no user data service, there are 2
things you can do:
 a.) mount an ubuntu image loopback, generate private ssh keys for the
host, set a password ...  basically make it so that you can get in even if
there is no data source.
 b.) try cirros (http://launchpad.net/cirros) upload and run one of those,
even if it fails to get the metadata service, you'll be able to log in
with password auth as 'cirros' with 'cubswin:)' as the password.
