>  That is actually the manifestation of a bug in Nova that was addressed
> very late in Folsom. The short version is that Nova inconsistently scoped
> the ownership of volumes vs. instances so it was possible for an admin user
> to view a mixed set of resources which could lead to the scenario you hit
> where things are in one list but not the other. I’m not sure if there’s any
> plans to backport the fixes from Nova. A patch could probably be worked up
> for the stable/essex Horizon branch that would avoid the keyerror (see the
> state of that code in Folsom:
> https://github.com/openstack/horizon/blob/stable/folsom/horizon/dashboards/nova/volumes/views.py#L68), but it would be papering over what is inherently a broken situation in
> Nova.****
