Public bug reported:

In launch instance modal, a user can choose a boot source.
When a user select 'Instance Snapshots', snapshots are listed.

However, these snapshots are not all.
At the moment, there are listed only snapshots created from a instance not creating new volume.

As far as I know, when a user create a snapshot created from a instance with new volume, it doesn't have image_type.
Instead of this, this has 'block_device_mapping' object. This object has 'source_type' attribute like below.

----
block_device_mapping='[{"guest_format": null, "boot_index": 0, "delete_on_termination": false, "no_device": null, "snapshot_id": "267a6729-056a-42b0-adaf-9d24eaeca67f", "device_name": "/dev/vda", "disk_bus": "virtio", "image_id": null, "source_type": "snapshot", "tag": null, "device_type": "disk", "volume_id": null, "destination_type": "volume", "volume_size": 1}]'

Horizon is judging by only image_type but it seems not to be enough.
