# Virtual Machine control structure (VMCS) Field IDs

Identify the fields of the virtual machine control structure.

## Overview

Overview Used by the functions hv_vmx_vcpu_read_vmcs(_:_:_:) and hv_vmx_vcpu_write_vmcs(_:_:_:). The VMCS fields are read-only or read-write by the Hypervisor framework, according to the following table: Readable and Writable VMCS Fields - Guest Fields  |   |   |   |   |   |   |   |   |   |   |   |   |   |   |  Readable and Writable VMCS Fields - Control Fields

Readable and Conditionally Writable VMCS Fields - Guest Fields  |   |   |  Readable and Conditionally Writable VMCS Fields - Control Fields  |   |   |   |   |   |  Read-Only VMCS Fields - Control Fields
