<p class="MsoNormal">Installed Devstack, created a volume, a snapshot and
launched an instance based on the snapshot. When I try to access the instance
details in Horizon, it blows up with this exception. Looks like some component
can’t handle cinder v2, where the display_name attribute has been replaced by
name. I found older bugs describing this issue, but they are marked as
fixed. Is this a known issue? Would appreciate help with a workaround.</p>
