STATUS_HV_OPERATION_FAILED
The operation reached Hyper-V, but this status is not enough to identify the subcondition
STATUS_HV_OPERATION_FAILED is a Hyper-V facility failure, but it is intentionally less specific than statuses such as invalid partition state, invalid device state, insufficient memory, or nested-virtualization restriction. It tells you the failing layer, not the exact corrective action.
For diagnosis, preserve the operation context before retrying. A generic operation failure can be the final status after a deeper check failed, a hardware capability was unavailable, a concurrent state transition raced the request, or a management service mapped a more specific internal error into this value.
What to collect
- The exact hypercall, WHP API, VMMS action, or driver request that returned the status.
- The partition, VP, device, GPA range, CPU group, or VTL object referenced by that operation.
- Any preceding Hyper-V, VMMS, worker-process, WHEA, storage, or device-assignment event.
- Whether the same request fails deterministically or only during concurrent create/destroy, migration, or resume.
Useful distinction
Do not replace more specific Hyper-V statuses with this one in logs. If an inner status is available, record it; otherwise this page can only guide evidence collection, not identify a single repair.
