It's a Cinder bug.
steps to reproduce: 
1. edit TestVM image property: 
glance image-update TestVM --property hw_disk_bus=ide --property hw_vif_model=rtl813

Here we see two new properties: Property 'hw_disk_bus'= ide and Property 'hw_vif_model'=rtl813

As you see here we have no information about image properties 'hw_disk_bus' and 'hw_vif_model' (it should be in dictionary 'volume_image_metadata')

expected:
volume_image_metadata dict in volume show information should be with dict 'properties'

{u'container_format': u'bare', u'min_ram': u'64', 
u'disk_format': u'qcow2', u'image_name': u'TestVM',
u'image_id': u'a375c384-7bcd-4844-b23e-f3f11a5252ac',
u'checksum': u'64d7c1cd2b6f60c92c14662941cb7913', 
u'min_disk': u'0', u'size': u'13167616',
u'properties': {u'hw_vif_model': u'rtl813', u'hw_disk_bus': u'ide'}} 

Actual:

volume_image_metadata dict in volume show information has NO dict 'properties'

{u'container_format': u'bare', u'min_ram': u'64', 
u'disk_format': u'qcow2', u'image_name': u'TestVM',
u'image_id': u'a375c384-7bcd-4844-b23e-f3f11a5252ac',
u'checksum': u'64d7c1cd2b6f60c92c14662941cb7913', 
u'min_disk': u'0', u'size': u'13167616'}
