Public bug reported:
Description
===========
When an exception raised by neutron，live migrate will be interrupt and vm
task_state keep in migrating.
Steps to reproduce
==================
1.Set the Token timeout after 5 minutes.
2.Login dashboard, and live-migrate an CentOS instance after 4
minutes(the token will timeout after 1min)
3.bug reproduced,because of neutronclient Authentication required
(token timeout)
Expected result
===============
Instance rollback or directly in error state.
Actual result
=============
Live migrate operation stoped，but instance task_state keeping in "migrating"
Environment
===========
version: Mitaka
hypervisor : Libvirt + KVM
storage: LVM
networking type: Neutron with OpenVSwitch
