</span>There seems to be a discrepancy in the rpcapi.py "kilo" alias between the Kilo and Liberty releases. In the Kilo release the compute alias is "kilo=3.40" but in Liberty it is "kilo=4.0". Setting the compute API version to 4.0 on the Kilo compute node or removing it entirely appears to resolve the issue. Though has either caused or led to another issue.<br>
<br>
I've testing and can live migrate from Kilo -> Liberty compute nodes, but fails on migrating from Liberty -> Kilo. I suspect another API version issue. With compute API level pined to 4.0 across all Nova nodes, the following error is raised in the Liberty Nova compute nodes log when I try live migrate from Liberty to Kilo;<br>

There appears to of been a few bugs raised previously for this. The 4.2 API version of live_migration with 7 parameters appears to be getting called with the 6 parameters from API version 4.0. I'm not sure why.<br>

I've unsuccessful tried the suggestion in the above and restarted all nova-conductor services to no effect.<br>
<br>
Any suggestions?<br>
