When multiple regions are used, nova api doesn't know to which cinder to reach out:

It's missing:

== nova.conf (nova-cloud-controller and nova-compute nodes) ==

[cinder]
os_region_name = <region>

== cinder.conf ==

[DEFAULT]
os_region_name = <region>

Unfortunately the config-flags option does not yet support non-DEFAULT sections so only the cinder entry can be added this way.

It's needed on both nova-cloud-controller and nova-compute nodes.

region is a config option for cinder and nova-cloud-controller so that should be trivial to add - nova-compute does not, but its related to nova-cc which does know the region, so it should be passed over that relation.
