1. Enable 'VMLiveUpdateFeatures' and 'vmRolloutStrategy'.

             "path": "/spec/configuration/developerConfiguration/featureGates",
             "value": ["VMLiveUpdateFeatures"]
         }, {
             "op": "add",
             "path": "/spec/configuration/vmRolloutStrategy",
             "value": "LiveUpdate"

2. Create a VM and set memory->maxGuest value.

          maxSockets: 8  # optional
        memory:
          guest: 2Gi
          maxGuest: 8Gi  # optional

3. Increase the memory->guest value by 2Gi. Wait the VM can be live migrated successfully.
4. Login the VM and check the new memory.
