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. The built-in message names the immediate result; the useful custom context is the exact boundary: lookup of a syntactically valid VID partition name that is not present. Record the first returning operation and host-side event before a management layer retries or translates it.
Locate the failing boundary
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.
Hyper-V architecture documentation identifies VID as the component that provides partition, virtual-processor, and memory-management services., many ERROR_VID_* values describe internal host objects rather than a public API that administrators should call directly. Accordingly, diagnose this result through the named object/state, the VMMS or Worker event chain, and the operation that produced it; do not invent a user-mode VID call from the constant name.
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. |
Preserve identifiers and counts without dumping guest secrets or unrelated memory. Useful this result timestamps include the last successful operation, first failure, any automatic retry, and the object-generation change that followed.
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.
Test the smallest supported create, lookup, initialize, or resource request that preserves the named condition. In the result reproduction, change one count, identity, or lifecycle step at a time and capture the first host event before retry.
Interpret three controls
Across these controls for it, preserve lookup of a syntactically valid VID partition name that is not present as the boundary under test.
| Control | Interpretation | Hold constant |
|---|---|---|
| Fresh owned object — this result | 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 generation. |
| Same request on a compatible host — it | 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 — it | Change one count, name, identity, or state transition. If it moves, the selected boundary is causal rather than the VM as a whole. | Keep host build, VM ID, and returning operation fixed for it. |
Keep neighboring states separate
A restart may release internal objects and make it disappear while erasing registration, ownership, resource-count, or teardown evidence. Capture the first result event chain before recovery.
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. Repeat the original operation under the original supported conditions and retain one deliberate negative control. A management command succeeding on a different object is not sufficient to close this incident.
