Hi all,
I have a set up with the following

Ubuntu 11.10
oneiric-proposed repo enabled

identity service - Daemons
ii  python-keystone
2012.1~e3~20120109.1511-0ubuntu0ppa1~oneiric1  Proposed OpenStack
identity service - Python library

I also have swift running on another host, working great with Keystone.

The problem I have is nova from the packages (versions above).  I'd
like to know what /etc/nova/api-paste.ini file I should be using.

I've tried various variations of this paste file and I can get nova to
work, but without keystone, or if I try to get keystone working I get
an error.

The file that I've been told should work with keystone and nova is:
https://github.com/openstack/keystone/blob/master/doc/source/nova-api-paste.rst

but this causes my nova-api to error

which is due to this line


[app:ec2md]
paste.app_factory =
nova.api.ec2.metadatarequesthandler:MetadataRequestHandler.factory

And viewing the python for this does in face come up empty for that
module (I'm no python programmer but presume this refers to
/usr/share/pyshared/nova/api/ec2/__init__.py where there are other
modules, but nothing referring to this?)

Has anyone seen this, aware of this - and best course of action to get
a resolution?  To me this seems a relatively logical approach to
installing Nova and Keystone and although people have reported success
with installation from source I'd prefer if there were plans or at
least acknowledgement that this is being addressed.

Cheers,
