Loads the pointer to the current virtual-machine control structure (VMCS) from the specified address.

int __vmx_vmptrld( 
   unsigned __int64 *VmcsPhysicalAddress 
);

Parameters

  • [in] *VmcsPhysicalAddress
    The address where the VMCS pointer is stored.

Return Value

  • 0
    The operation succeeded.

  • 1
    The operation failed with extended status available in the VM-instruction error field of the current VMCS.

  • 2
    The operation failed without status available.
