Bug Description
When using Cinder-backed images inside Glance in combination with Active-Active, it leads to a situation where the original image would fallback to the download image flow which can be very taxing on environments.
The root cause of this is that Cinder tries to find for any matching volumes that _only_ match on the host the volume is being launched on, which makes sense in a non clustered Cinder environment, but does not make sense in an environment where the base volume can potentially be accessible in the cluster, but on a differnet host.
The code in question is the following:

This should be fixed with the patch[1]
I found the same issue while testing multiple glance cinder stores with different backend configuration, see my comment on the review for the that scenario.
