NTHV_GUEST_ERROR
Hyper-V guest fatal error for NTHV_GUEST_ERROR
NTHV_GUEST_ERROR is bug check code 0x00000118. This bug check is tied to a Windows guest running with Hyper-V or enlightenment interfaces. It indicates a fatal condition in the guest/hypervisor contract rather than a generic application-level crash.
How to read it in a dump
- Check whether the system is a VM or uses virtualization-based security.
- Hypervisor version, virtual hardware, synthetic devices, and integration components are key evidence.
- The dump should be correlated with host logs when available.
What to check
- Review recent host, hypervisor, and guest integration updates.
- Check virtual hardware configuration and VBS/Hyper-V settings.
- Collect both guest dump and host event logs if the machine is virtualized.

Dump evidence
Preserve the complete dump, the four bug-check parameters, the exact Windows build, loaded-module list, and the event timeline immediately before the stop. AllStat summarizes the condition as “this result”; that sentence identifies the failure class, while the parameters and stack determine which object, driver, processor, or subsystem instance was involved.
Analysis order
- Run WinDbg
!analyze -v, then inspect the documented meaning of each parameter instead of relying only on the probably-caused-by line. - find the earliest abnormal event: driver update, firmware change, device reset, storage error, verifier report, resource exhaustion, or application hang connected with nthv / guest.
- keep third-party filter, security, storage, graphics, and virtualization drivers in the module inventory; removing evidence before dump analysis can obscure the responsible path.
Do not repeatedly reboot a machine affected by this result before collecting the dump and event logs. Recovery actions should follow the component identified by the stack and parameters, not merely the symbolic stop-code name.
