+### Parent Groups
+
+VM types can declare a `parent_group` to be aggregated under a shared
+inventory group while remaining independently targetable.
+
+When `parent_group` is set on a VM type, the role:
+
+1. Creates the subtype inventory group as usual (e.g. `compute94s`, `compute96s`).
+2. Adds each VM to both the subtype group and the parent group.
+3. Emits a parent group entry in `all-group.yml` with `children:` listing
+   all subtypes that share it.
+4. Generates a single combined networking entry under the parent group name,
+   with an IP range length equal to the sum of all subtypes' amounts.
+
+This means plays targeting `computes` will reach all compute VMs regardless
+of subtype, while plays targeting `compute94s` or `compute96s` will reach
+only that subset.
+
+A parent group is abstract -- it exists only as a grouping mechanism and
+must not correspond to an actual VM type in the layout. If you use
+`parent_group: computes`, there must be no `compute:` entry in the
+`vms` dictionary. The parent group is defined entirely by its children.
+
+All subtypes sharing a parent group must declare the same `parent_group`
+value and the same set of `nets`.
+
+#### Example
+
+```YAML
+cifmw_libvirt_manager_configuration:
+  vms:
+    compute94:
+      amount: 1
+      disk_file_name: base-os-94.qcow2
+      image_url: "https://example.com/rhel-9.4.qcow2"
+      parent_group: computes
+      nets:
+        - ocpbm
+        - osp_trunk
+    compute96:
+      amount: 2
+      disk_file_name: base-os-96.qcow2
+      image_url: "https://example.com/rhel-9.6.qcow2"
+      parent_group: computes
+      nets:
+        - ocpbm
+        - osp_trunk
+    controller:
+      disk_file_name: base-os.qcow2
+      nets:
+        - ocpbm
+        - osp_trunk
+```
+
+This produces three inventory groups for computes:
+
+- `compute94s` -- contains `compute94-0`
+- `compute96s` -- contains `compute96-0`, `compute96-1`
+- `computes` -- parent group containing both `compute94s` and `compute96s`
+  as children
+
+The generated `all-group.yml` will include:
+
+```YAML
+all:
+  children:
+    compute94s:
+      vars: ...
+    compute96s:
+      vars: ...
+    computes:
+      children:
+        compute94s: {}
+        compute96s: {}
+```
+
