my students of this week traning, have a question about HA and failback:

We have 3 host :


an HA group "kvm23" with kvm2 && kvm3

We have a vm , with HA enable in group kvm23,with "nofailback" not enabled, "restricted" not enabled and vm is running on kvm3.

kvm3 crash.

the vm is restarted by HA to kvm2

kvm3 is back online.

vm does not failback to kvm3 ?

The documentation said that it should failback to prefered node. But what is the prefered node ? any member of the group ?

Students expected that vm fallback to last node before the crash.
