In the process of a Kilo to Liberty upgrade and cannot live migrate VMs between Kilo and Liberty compute hosts. The Control nodes and a single Compute node have been upgraded to Liberty. We get the following error in the compute nodes log when we attempt to live migrate a instance from the Kilo node to the Liberty node;<br>

<br>
Upgrade level has been set to "kilo" on all Nova Control and Compute nodes in /etc/nova/nova.conf;<br>
[upgrade_levels]<br>
compute = kilo<br>
<br>
Similar errors are raised during an offline migration or resize. Live migration worked correctly with Liberty Control nodes and Kilo Compute nodes. Instances can be booted and run on both Liberty and Kilo Compute nodes. Any idea what's going on here?<br>
