Public bug reported:

When using the cinder backed images as per

https://docs.openstack.org/cinder/latest/admin/blockstorage-volume-
backed-image.html

We have multiple locations, glance configured as

/etc/glance/glance-api.conf

[glance_store]
stores = swift, cinder
default_store = swift
-snip-
cinder_store_auth_address = https://hostname:5000/v3
cinder_os_region_name = Region
cinder_store_user_name = glance
cinder_store_password = Password
cinder_store_project_name = cinder-images
cinder_catalog_info = volume:cinder:internalURL


cinder clones the volume correctly, then talks to glance to add the location of cinder://

glance then talks to cinder to validate the volume id, however this step
uses the wrong cinder endpoint and checks the other region.

>From /usr/lib/python2.7/site-packages/glance_store/_drivers/cinder.py

It appears the region name is only used when not passing in the
project/user/password.

Passing the os_region_name to the cinderclient.Client call on line 351
appears to fix this.

ie

    c = cinderclient.Client(username,
                            password,
                            project,
                            auth_url=url,
                            region_name=glance_store.cinder_os_region_name,
                            insecure=glance_store.cinder_api_insecure,
                            retries=glance_store.cinder_http_retries,
                            cacert=glance_store.cinder_ca_certificates_file)
