Public bug reported:
Description
===========
If libvirt is unable to detach a volume because it's still in-use by the guest
(either mounted and/or file opened), nova returns a traceback.
Steps to reproduce
==================
* Create an instance with volume attached using heat
* Make sure there's activity on the volume
* Delete stack
Expected result
===============
We would expect nova to not return a traceback but a clean log about its
incapacity to detach volume. If possible, that would be great if that exception
was raised back to either cinder or heat.
Actual result
=============
