Having an instance disappear isn't enough to know the things were
cleaned up successfully. Instead we should sort out why the instance
disappeared, that shouldn't happen.

Title:
The instance's task_state is "deleting" all the time, because the
error of "Instance disappeared during terminate".
Status in OpenStack Compute (Nova):
Invalid
Bug description:
A instance's vm_state is error. I did delete it, but the task_state
is "deleting" all the time. The log show that the error is "Instance
disappeared during terminate" because of InstanceNotFound exception.
1. Relative code is as follows:
@utils.synchronized(instance['uuid'])
def do_terminate_instance(instance, bdms):
try:
self._delete_instance(context, instance, bdms, quotas)
except exception.InstanceNotFound:
LOG.info(_("Instance disappeared during terminate"),
instance=instance)
except Exception as error:
# As we're trying to delete always go to Error if something
# goes wrong that _delete_instance can't handle.
with excutils.save_and_reraise_exception():
LOG.exception(_('Setting instance vm_state to ERROR'),
instance=instance)
self._set_instance_error_state(context, instance['uuid'])

4. I think if instance is disappeared, delete would be successful.
