Public bug reported:

Description
===========
I'm going to test the feature that rescuing a server booted from *image*.
I created a server as usual and I can login and do anything.

when I rescued it with password, and without specifing image, it's ok
that changed status as RESCUE, but I can not login the server.


Steps to reproduce
==================
$ openstack server create --image <> --flavor <> --network <> test-rescue
$ nova set-password test-rescue
$ virsh console <>
# Login successful

$ openstack rescue --password qweasd test-rescue
$ virsh console <>
# Login incorrect

Expected result
===============
I can use password set in rescue cmd to login the server in rescue status.

Actual result
=============
I can not use old or new password to login the server

Environment
===========
1. Exact version of OpenStack you are running.
   My openstack version is *T*.


2. Which hypervisor did you use?
   My hypervisor is KVM+Qemu+Libvirt

2. Which storage type did you use?
   CephRBD

3. Which networking type did you use?
   Neutron+OpenVSwitch

Logs & Configs
==============
I get the disk xml config, and I found the index of .rescue disk is 3, it should had been 1, right?

$ virsh dumpxml instance-xxxxx
