Hi all,

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 :

3b-4810-b5a4-f415c90ffdca`::Failed to migrate

libvirtError: unsupported configuration: NUMA node 1 is unavailable

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