I'm in the process of a Kilo to Liberty migration and am encountering
this exact same issue when we attempt to live migrate instances from a
Liberty to a Kilo Compute node. The Compute API is pinned to 4.0.

I've attempted Johns suggestion and restarted all nova-conductor
services but it has had no affect.

Are there any suggestions and/or workarounds for this issue?

Title:
  live_migration() takes exactly 7 arguments (6 given) if upgrade_levels
  compute=kilo

Status in OpenStack Compute (nova):
  New

Bug description:
  I have Liberty controller (nova-api, etc.) with

  [upgrade_levels]
  compute=kilo

  and Liberty compute node, when i try live-migration
  i see "live_migration() takes exactly 7 arguments (6 given)"
  in nova-compute.log.

  I can not completely remove compatibility with kilo,
  because i have kilo computes in my env.

  I also tried to add "upgrade_levels" to compute node,
  but with no luck.

  Environment
  ==========
  Libvirt+KVM, Ceph for VMs
  Liberty - Mirantis OpenStack 8.0 (2015.2)

  Steps to reproduce
  ===============
  1) Install Liberty control plane (api, conductor, schduler, etc.)
  2) Install Liberty computes
  3) Add to nova.conf on controller
    [upgrade_levels]
    compute=kilo
  3) Try "nova live-migration VM"

  Expected result
  =============
  Migration will succeed

  Actual result
  ==========
  Traceback on compute node
