Public bug reported:

Description
===========
At first use one volume as bootable device for the instance,
then use another attached bootable volume as the instance's 
bootable device.
But when detaching the first volume from the instance,
got error.

Steps to reproduce
==================
* Boot instance vm01 from volume vol01 
* Create another volume vol02 from image, update 'bootable' is true
* Shutoff vm01
* Attach vol02 to vm01
* Update 'bootable' of vol01 to false
* Start vm01
* Detach vol01 from vm01

Expected result
===============
Detach successfully

Actual result
=============
Failed to detached

Environment
===========
1. Exact version of OpenStack you are running.
