/*

13
 * We do NOT shadow fields that are modified when L0

14
 * traps and emulates any vmx instruction (e.g. VMPTRLD,

15
 * VMXON...) executed by L1.

16
 * For example, VM_INSTRUCTION_ERROR is read

17
 * by L1 if a vmx instruction fails (part of the error path).

18
 * Note the code assumes this logic. If for some reason

19
 * we start shadowing these fields then we need to

20
 * force a shadow sync when L0 emulates vmx instructions

21
 * (e.g. force a sync if VM_INSTRUCTION_ERROR is modified

22
 * by nested_vmx_failValid)

23
 *

24
 * When adding or removing fields here, note that shadowed

25
 * fields must always be synced by prepare_vmcs02, not just

26
 * prepare_vmcs02_rare.
