I think this is one of those edge cases that the work around you
provided is the right way through. The decorating on images is meant to
be part of the original image build process, and doesn't magically fix
things.

Title:
Instance with two attached volumes fails to start with error:
Duplicate ID 'drive-ide0-0-0' for drive
Status in OpenStack Compute (nova):
Won't Fix
Bug description:
nova version: mitaka
I imported into Openstack a Linux Centos machine. The instance does
not have support for VirtIO. I had to import the boot disk as hda
(decorating the glance image with hw_disk_bus='ide'). Now I have this
instance with two volumes attached, but when I try to boot the
following XML is generated.
<disk type='network' device='disk'>
<driver name='qemu' type='raw' cache='writeback'/>
[..CUT...]
<target dev='hda' bus='ide'/>
<serial>c3841ee3-3f9a-457e-b504-d35e367a1193</serial>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
<disk type='network' device='disk'>
<driver name='qemu' type='raw' cache='writeback'/>
[..CUT...]
<target dev='vda' bus='ide'/>
<serial>63e05c59-8de1-4908-a3dd-3f2261c82ea9</serial>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
This is because the two cinder volumes attached appear as /dev/hda and
/dev/sda, and this creates a duplicate disk in the XML.
The machine does not boot, and in the nova-compute.log I find a
stacktrace.

In liberty the two disked attached where marked as /dev/sda /dev/hdb,

two attachments are marked as /dev/sda and /dev/hda and the VM is not
booting.
