Title:
Attaching volume to iso instance is failure because of duplicate
device name 'hda'.
Status in OpenStack Compute (nova):
Fix Released
Status in OpenStack Compute (nova) juno series:
Fix Released
Bug description:
I try to attach a volume to iso instance, return code of volume-attach
api is 200 ok, but the volume can't be attached to instance in fact,
there are some error messages in nova-compute.log like this
'libvirtError: Requested operation is not valid: target hda already
exists'.
The root device of iso instance is hda, nova-compute should not assign
hda to cinder volume again.
The following is reproduce steps:
1. boot instance from iso image.
2. create a cinder volume.
3. try to attach the volume to iso instance.
Attaching volume is failed, I can find libvirt error in nova-
compute.log.
