Old style Images with vhd files tarred along with a folder are not handled in nova xen plugin

[Sumanth Nagadavalli]

There are some legacy snapshots which are uploaded into swift, with vhd files bundled in a folder called "image".

They are in the below format,
image/
            snap.vhd
            image.vhd

Right now, in glance plugin, after downloading the image, when we try to handle old style images, we expected vhd files to be downloaded in the staging_path.

But in this case of legacy images, there is a folder called "image" with vhd files, downloaded in the staging path.

So, the level of recursiveness in the downloaded image is not supported today, while handling old style image.

This feels a lot like a feature to me... This may require a blueprint.

No updates, and no patch, so marking this as no longer in progress. Please do update if this is false.

This wishlist bug has been open a year without any activity. I'm going to move it to "Opinion / Wishlist", which is an easily-obtainable queue of older requests that have come on.

In case you want to work on that, consider writing a blueprints [1] and spec [2]. I'll recommend to read [3] if not yet done. The effort to implement the requested feature is then driven only by the blueprint (and spec).
