Public bug reported:

Nova Juno

The instance snapshot of volume backed instances does not handle image
metadata the same way that the regular instance snapshot path does.

nova/compute/api/api.py's snapshot path builds the Glance image metadata
using nova/compute/utils.py get_image_metadata which gets metadata from
the VM's base image, includes metadata from the instance's system
metadata, and excludes properties specified in
CONF.non_inheritable_image_properties.

The volume backed snapshot path,
http://git.openstack.org/cgit/openstack/nova/tree/nova/api/openstack/compute/servers.py#n1472
simply gets the image properties from the base image and does not
include properties from instance system metadata and doesn't honor the
CONF.non_inheritable_image_properties property.
