It seems due to change of non-live-updatable field in the VM spec:

I think due to change of: containerDisk.image it is creating the problem

Last time for similar issue, we fixed by renaming the VM names so that re-creation will be triggered and no need to restart will be required

!4489 (merged)

But each time, doing this seems not feasible. so need some better way
