/*

* 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_full.
