reviewing the steps rene performed and the initial bug description this
work flow is not supported

nova has never supported attaching a volume to a guest via the cidner API 
and detaching it has been explicitly blocked due to the cve exposures 

so for nova i belive this is invalid.

cinder likely should prevent normal user form creating attachments for a
nova instance with the same mitigation as the detach case.

creating a volume attachment for a nova instance should require a service token with the service role
just as delete does.

** Changed in: nova
       Status: New => Invalid

Title:
  Regarding Nova's inability to delete the Cinder volume for creating
  virtual machines (version Y)

Status in Cinder:
  Confirmed
Status in OpenStack Compute (nova):
  Invalid

Bug description:
  When creating a virtual machine in the dashboard, create a volume and
  choose to delete the virtual machine while also deleting the volume.
  When deleting the virtual machine, there is no normal uninstallation
  of the volume and the volume is not deleted.

  The relevant error logs are shown in the image, but the openstack CLI
  can delete its volume. The specific commands are as follows.

  CLI：

  source /etc/keystone/admin-openrc.sh (Verify password file)
  openstack volume set --detached　191e555c-3947-4928-be46-9f09e2190877（volumeID）
  openstack volume delete  191e555c-3947-4928-be46-9f09e2190877（volumeID）

  It seems that Nova is unable to interact with the Cinder API to
  delete(or detached) commands, but I am not very professional. I don't
  know if it's a bug?
