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.
** Changed in: nova Status: New => Won't Fix -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1686999 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. 2017-04-28 12:56:35.356 43378 ERROR oslo_messaging.rpc.dispatcher Traceback (most recent call last): 2017-04-28 12:56:35.356
