For now , i can't change the kubevirtMachineTemplate when the cluster is running and i also try to change the kubevirtmachine , it return configured but did't change the VM and restart it , is there any way that can change it?

@davidvossel -- do you happen to know if there's a need or a plan to support this?

For us, machineTemplates are meant to be immutable.

The procedure for changing the template would be to

  1. create a new template with the desired changes
  2. update the MachineSet or MachineDeployment to point to the new template
  3. Those controllers will then rollout the new changes.
