ERROR_VID_PARTITION_NAME_NOT_FOUND
ERROR_VID_PARTITION_NAME_NOT_FOUND is HRESULT 0xC037000A in the VID partition name lookup area of the Windows virtualization stack. It applies to lookup of a syntactically valid VID partition name that is not present.
Where the result originates
The name passes validation but does not resolve on the current host. Investigate wrong host, stale configuration, rename/import transformation, and timing relative to partition creation.
Neighboring result: INVALID_OBJECT_NAME means validation failed; PARTITION_DOES_NOT_EXIST can involve any absent object reference. NAME_NOT_FOUND specifically directs attention to lookup key and namespace.
Build an incident record
| Evidence | Why it changes the diagnosis |
|---|---|
| Lookup name | Record exact UTF-16 value, case, prefix, and host. |
| Expected source | Keep VM configuration ID and the code that derived the internal name. |
| Host inventory | Capture currently registered VMs/partitions and worker states. |
| Timing | Place lookup relative to create, import, rename, migration, and teardown. |
Run narrow checks
- Enumerate the target host rather than assuming local and remote namespaces match.
- Compare generated name with the value used at successful creation.
- Wait on explicit creation completion, not an arbitrary delay.
- Avoid falling back to a similarly named partition.
Interpret three controls
| Control | Interpretation | Hold constant |
|---|---|---|
| Fresh owned object | A clean lifecycle changing this result implicates duplicate initialization, leaked ownership, stale lookup, or incomplete rollback. | Preserve request flags and topology while changing only object instance. |
| Same request on a compatible host | If it follows one host, compare resource limits, topology, build, and inventory before altering VM data. | Use the same request and leave virtual disks unchanged in the result comparison. |
| One operation parameter | Change one count, name, identity, or state transition. If it moves, the selected condition is causal rather than the VM as a whole. | Keep host build, VM ID, and returning operation fixed. |
Keep neighboring states separate
Prove the correction
The lookup resolves the intended partition by stable identity on every supported lifecycle path and fails safely for a deliberate unknown name.
