STATUS_VID_INVALID_PPM_HANDLE
Invalid parent-partition mapping handle
STATUS_VID_INVALID_PPM_HANDLE points to a parent-partition mapping object. In Hyper-V architecture the parent, or root, partition hosts the management OS and virtualization stack that backs child partitions.
The invalid object is specifically a parent-partition mapping (PPM) handle, which belongs to the host-side relationship used to map partition memory. Preserve the create/destroy order for that mapping and verify that a handle from an earlier partition instance was not reused after the VM worker or partition was recreated.
A PPM handle failure usually means the mapping between host-side resources and child GPA backing state is stale, wrong for the partition, or already torn down.
What to inspect
- Verify the handle was created for the same parent/child partition relationship used by the failing operation.
- Check for migration, reset, or worker-process restart between mapping creation and use.
- Do not diagnose it as a guest pointer problem; the failed handle belongs to the host mapping layer.
