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
