  9.  * We do NOT shadow fields that are modified when L0
    10. 

  10.  * traps and emulates any vmx instruction (e.g. VMPTRLD,
    11. 

  11.  * VMXON...) executed by L1.
    12. 

  12.  * For example, VM_INSTRUCTION_ERROR is read
    13. 

  13.  * by L1 if a vmx instruction fails (part of the error path).
    14. 

  14.  * Note the code assumes this logic. If for some reason
    15. 

  15.  * we start shadowing these fields then we need to
    16. 

  16.  * force a shadow sync when L0 emulates vmx instructions
    17. 

  17.  * (e.g. force a sync if VM_INSTRUCTION_ERROR is modified
    18. 

  18.  * by nested_vmx_failValid)
    19. 

  19.  *
    20. 

  20.  * When adding or removing fields here, note that shadowed
    21. 

  21.  * fields must always be synced by prepare_vmcs02, not just
    22. 

  22.  * prepare_vmcs02_full.
