Public bug reported:

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.

https://github.com/openstack/nova/blob/master/plugins/xenserver/xenapi/etc/xapi.d/plugins/utils.py#167

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.
