    Instance remains in migrating state forever
    
    An unexpected failure during live migration leaves the instance
    to migrating state forever.
    The issue is that in case of unexpected failure the task state is
    set to be same as the instance task state. It should be set to
    'None' instead.

Title:
  Live migration failure during detach volume leaves the instance task
  state to migrating forever

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Description
  ===========
  Live migration failure during detach volume leaves the instance task state to migrating forever.

  Steps to reproduce
  ==================
  - Deploy a VM on a host (the source host) and ensure that vm is in active and running state.
  - Pick one of the host in the environment to be destination host and make changes so that a detach volume operation from the destination host would fail.
  - Trigger the VM migration operation.
  Expected result
  ===============
  - VM migration should fail.
  - VM should go into error state.
  - VM task state is set to None.

  Actual result
  =============
  - VM migration failed.
  - VM went into error state.
  BUT
  - the VM task state remained in migrating state.

  Environment
  ===========
  1. Exact version of OpenStack you are running.
