Status in OpenStack Compute (nova):
  Invalid

Bug description:
  The instance is volume backed and power state is PAUSED，shelve the
  instance failed. The reason is that can not attempt a clean shutdown
  of a paused guest instance some hypervisors will fail the clean
  shutdown if the guest is not running.

  Description
  ===========
  The instance is booted from volume, and pause the instance in paused status, and
  shelve this instance. But this instance's status is only paused not shelved.

  Steps to reproduce
  ==================
  1.Boot an instance from volume.
  2.Pause the instance.
  3.shelve the instance.

  Expected result
  ===============
  This instance's status is shelved.

  Actual result
  =============
  This instance's status is paused.

  Environment
  ===========
  1. OpenStack Rocky version
  2.Hypervisor is kvm
  3.The storage is Ceph
  4.Networking is Neutron with OpenVSwitch
