Comment 2 for bug 1447215

I used slightly different reproduction steps.

# glance --os-image-api-version 1 image-list

# glance --os-image-api-version 2 image-list
None is not of type u'string'

Failed validating u'type' in schema[u'properties'][u'ramdisk_id']:
    {u'description': u'ID of image stored in Glance that should be used as the ramdisk when booting an AMI-style image.',
     u'is_base': False,
     u'pattern': u'^([0-9a-fA-F]){8}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){12}$',
     u'type': u'string'}

On instance[u'ramdisk_id']:
    None

The proposed fix https://review.openstack.org/#/c/176379/2 fixes the problem.

All VM snapshot images created by libvirt KVM driver in Nova that did not have ramdisk or kernel_id values will exhibit this behavior and they will fail to boot/spawn/deploy when Nova moves to use Glance v2.

Image using the rbd ephemeral snapshot code, https://review.openstack.org/#/c/125963/, are already exhibiting the failure behavior because this spawn path uses a Glance v2 show call to get image locations.
