I created a cluster of VM with the same CPu level, except that one of them only has one physical CPU. When trying to migrate, I get this message into engine.log :<br>

libvirtError: unsupported configuration: NUMA node 1 is unavailable<br>
<br>
It seems that engine allows to mix multinode and mononode host into a same cluster whereas vms can't migrate between these nodes.<br>
I've never been using and configuring NUMA until now, so I don't understand why we are not allowed to migrate vms.*<br>
Thank you for your help<br>
