   If your code is using those arguments / passing them to the `create_node()`
   method it needs to be updated and those arguments removed.
 
+* [KubeVirt] Changes to the `create_node()` method: 
+
+  - The `ports` argument has been renamed to `ex_ports`. 
+  - The `ex_disks` argument has been redefined to support all volume types. 
+
+  The deprecated `ex_disks` format, which only supports `PersistentVolumeClaim`,
+  is as follows:
+
+  .. sourcecode:: python
+
+    ex_disks=[{"bus": "", "device": "", "disk_type": "", "name": "", "claim_name": "", "size": "", "storage_class_name": "", "volume_mode": "", "access_mode": ""}]
+
+  The new format is:
+
+  .. sourcecode:: python
+
+    ex_disks=[{"bus": "", "device": "", "disk_type": "", "name": "", "volume_spec": {...}}]
+
+  Here, `volume_spec` is the `disk_type` specific settings, which aligns with the 
+  KubeVirt user guide on disks and volumes 
+  (https://kubevirt.io/user-guide/virtual_machines/disks_and_volumes). 
+
+  For example, for PVC:
+
+  .. sourcecode:: python
+
+    ex_disks=[{ ..., "volume_spec": {{"claim_name": "", "size": "", "storage_class_name": "", "volume_mode": "", "access_mode": ""} }]
+
+  If your code uses these arguments or passes them to the `create_node()`
+  method, it will need to be updated accordingly.
