0013  * We do NOT shadow fields that are modified when L0
0014  * traps and emulates any vmx instruction (e.g. VMPTRLD,
0015  * VMXON...) executed by L1.
0016  * For example, VM_INSTRUCTION_ERROR is read
0017  * by L1 if a vmx instruction fails (part of the error path).
0018  * Note the code assumes this logic. If for some reason
0019  * we start shadowing these fields then we need to
0020  * force a shadow sync when L0 emulates vmx instructions
0021  * (e.g. force a sync if VM_INSTRUCTION_ERROR is modified
0022  * by nested_vmx_failValid)
0023  *
0024  * When adding or removing fields here, note that shadowed
0025  * fields must always be synced by prepare_vmcs02, not just
0026  * prepare_vmcs02_rare.
