virt-builder metadata for Debian cloud images


(please keep me CC'ed, as I'm not subscribed)

I'm one of the upstream of the libguestfs [1] project, which is a
library and a set of tools to manipulate disk images. It is also
packaged in Debian.

One of the tools is virt-builder [2], which allows to create quickly
new guests starting from templates. So far, we are providing all the
templates ourselves on our website, and some of them are also Debian
stable images:

Speaking with Thomas Goirand (zigo), I was told about the OpenStack
images [3], so it would be nice to have them available in virt-builder
for the users of this tool.

Basically, it is matter to provide an index file, INI-like style, with
the proper metadata for each image (name, description, size, sha512,
etc), optionally GPG-signed inline (it is not mandatory, although would
be recommeded). You can check the configuration bits in the
"SOURCES OF TEMPLATES" section of [2], and also the current index on
libguestfs.org [4] as example.
To use this index, there would be the need to install locally (i.e.
where virt-builder is installed) a very small .conf file (and the copy
of the GPG key, if the index is signed); the files for the
libguestfs.org are currently part of the libguestfs-tools package
(together with virt-builder), installed under

I would be happy to help in getting the online metadata (i.e. the
index, possibly signed) generated, so how would I get to it?

Also, a different chapter would be having proper non-cloud qcow2
images available (always with virt-builder metadata, of course).
This, other than allowing us to avoid maintaining Debian images, would
mean virt-builder users can get official images of stable released,
updated periodically.
Would that be something useful? If so, how/where/etc could this process
get started?
