How does it work? Being triggered, the Node Fairness service determines the current workload on the cluster hosts. If needed, it automatically migrates VMs to the less loaded host. After the start, the cluster service checks the host for two factors: If the average host CPU load exceeds the tolerated threshold If the average host memory utilization is higher than the tolerated threshold In case either of these criteria is met, the VM gets live migrated to the less loaded host. Neither guest system nor services do experience any downtime.

Tune your live migration settings in Hyper-V for faster, smoother VM moves — especially in clustered setups.

Set up your Hyper-V environment to boot VMs in the correct order every time, keeping dependent services happy and downtime minimal.
