commit 34b8336a41e2896f0639c402f64a05247f475fea Author: Wenzhi Yu <[email protected]> Date: Thu Apr 28 16:06:57 2016 +0800 Make compute rpcapi 'live_migration' backward compatible This commit[1] added compute rpcapi version 4.2 which introduced a new argument 'migration' when calling 'live_migration' method, but the code did not ensure the backward compatibility with older version compute node. When calling 'live_migration' method with 'migration' argument on older version(like Kilo) of nova compute node, a "TypeError: live_migration() got an unexpected keyword argument 'migration'" will be threw up.

Liberty control plane and Kilo compute nodes. Doing live-migration and getting error below on compute node TypeError: live_migration() got an unexpected keyword argument 'migration' Workaround(On controller): http://paste.openstack.org/show/495612/ Environment ========== Libvirt+KVM, Ceph for VMs Liberty - Mirantis OpenStack 8.0 (2015.2) Kilo - 2015.1.3 tag Steps to reproduce =============== 1) Install Liberty control plane (api, conductor, schduler, etc.) 2) Install Kilo compute 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 http://paste.openstack.org/show/495541/ To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1576048/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
