Other than the leading ", that looks fine.  I suspect you did not mean the
leading quote.

Well, the above is indicating that there is no user-data available to the
instance.  Ie, it is "".  I actually just committed a *removal* of this
warning in cloud-init as I had previously thought it just an annoying
message.

You can verify from inside the instance that there is no user-data, with
'ec2metadata --user-data' or 'wget http://169.254.169.254/latest/user-data'

Sorry, without digging/learning more, I can't help more.
Have you tried the python-novaclient:
  nova boot --user_data my.user.data.file.txt ...

Ie, try verifying that it is working with known working tools on your
openstack first.  Alternatively, if the ec2 api is available, that looks
like:
   euca-run-instances --user-data-file my.user.data.file.txt ...

I dont see anything obviously wrong, but I'd try using the knonw orking
tools first.  I think python-nova client even has a --debug to dump what
it is sending.
