NDIS_HYPERVISOR_INFO structure

Important  

Starting with Windows 10 Version 1703, NDIS_HYPERVISOR_INFO is deprecated and should not be used. Drivers are encouraged to move away from it, as it may not be available in future versions of the operating system.

Drivers should instead follow a hypervisor's instructions to query hypervisor presence and capabilities. For example, Hyper-V's instructions are documented in the Top-Level Functional Specification.

 
The NDIS_HYPERVISOR_INFO structure contains information about the hypervisor that is present on the system.

Syntax

typedef struct _NDIS_HYPERVISOR_INFO {
  NDIS_OBJECT_HEADER             Header;
  ULONG                          Flags;
  NDIS_HYPERVISOR_PARTITION_TYPE PartitionType;
} NDIS_HYPERVISOR_INFO, *PNDIS_HYPERVISOR_INFO;

Members

Header

The type, revision, and size of the NDIS_HYPERVISOR_INFO structure. This member is formatted as an NDIS_OBJECT_HEADER structure.

The miniport driver must set the Type member of Header to NDIS_OBJECT_TYPE_DEFAULT. To specify the version of the NDIS_HYPERVISOR_INFO structure, the driver must set the Revision member of Header to the following value:

NDIS_HYPERVISOR_INFO_REVISION_1

Original version for NDIS 6.20.

Set the Size member to NDIS_SIZEOF_HYPERVISOR_INFO_REVISION_1.

Flags

A ULONG value that contains a bitwise OR of the following flag.

NDIS_HYPERVISOR_INFO_FLAG_HYPERVISOR_PRESENT

Specifies that a hypervisor is present on the system.

PartitionType

An NDIS_HYPERVISOR_PARTITION_TYPE enumeration value that specifies the partition type that is running on the hypervisor.

Remarks

The NDIS_HYPERVISOR_INFO structure specifies the hypervisor information that is returned by the NdisGetHypervisorInfo function.

NDIS drivers pass this structure to the NdisGetHypervisorInfo function.

Requirements

   
Minimum supported client Supported in NDIS 6.20 and later.
Header ntddndis.h (include Ndis.h)
