| * We do NOT shadow fields that are modified when L0 |
| * traps and emulates any vmx instruction (e.g. VMPTRLD, |
| * VMXON...) executed by L1. |
| * For example, VM_INSTRUCTION_ERROR is read |
| * by L1 if a vmx instruction fails (part of the error path). |
| * Note the code assumes this logic. If for some reason |
| * we start shadowing these fields then we need to |
| * force a shadow sync when L0 emulates vmx instructions |
| * (e.g. force a sync if VM_INSTRUCTION_ERROR is modified |
| * by nested_vmx_failValid) |
| * |
| * When adding or removing fields here, note that shadowed |
| * fields must always be synced by prepare_vmcs02, not just |
| * prepare_vmcs02_rare. |

| /* |
| * Keeping the fields ordered by size is an attempt at improving |
