** Description changed:
+ === Begin SRU Information ===
+ [Impact]
+ CloudStack provides an EC2-style metadata server which cloud-init consumes.
Unfortunately, the CloudStack metadata server does not exactly match the
behaviour of the EC2 metadata server. When an instance using cloud-init is
booted in a CloudStack environment, it will fail to retrieve metadata from the
metadata server. This leads to cloud-init bailing out and making no changes to
the instance, generally rendering it inaccessible and unusable.
+
+ This patch changes all access to EC2-style metadata servers. Instead of
+ accessing http://.../meta-data to determine the available metadata,
+ cloud-init will access http://.../meta-data/ (i.e. with an added
+ trailing slash).
+
+ [Test Case]
+ Booting an Ubuntu image configured to use the CloudStack data source within a
CloudStack cloud environment. If (for example) the instance name is set
correctly, then the fix has worked.
+
+ [Regression Potential]
+
+ Regression potential is low; this patch does affect more than just the
+ CloudStack data source, but it is backported from the version of cloud-
+ init in utopic which has been observed working.

Hi,
Cloud-init 0.7.5 fails to get cloudstack user-data because of trailing
slash (ok in previous versions).
As a temp workaround I use the following patch in url_helper.py line 239
(0.7.5-0ubuntu1):
- if e.response.status_code == 404:
- if url.endswith("/"):
- url = url[:-1]
- req_args["url"] = url
- else:
- url = url + "/"
- req_args["url"] = url
+ if e.response.status_code == 404:
+ if url.endswith("/"):
+ url = url[:-1]
+ req_args["url"] = url
+ else:
+ url = url + "/"
+ req_args["url"] = url
-
- I don't know how other products (EC2, openstack & co) deal with trailing slash
+ I don't know how other products (EC2, openstack & co) deal with trailing

Hope that helps
Thanks
