privileged instruction

基本解释

In the end, they had a version of the BSD kernel running as a process on top of their microkernel and calling down to Mach instead of executing privileged instructions.
最後，他們使用了某一版本的BSD內核，作爲進程運行在他們的微內核上層，調用Mach，而不是運行特權指令。
The System/390 architecture allowed complete virtualization of the machine, including even the "privileged" instructions that simply ran inside the sandbox created for them.
System/390 架搆支持機器的完全虛擬化，甚至包括衹能在爲虛擬機創建的沙箱中運行的“特權”指令。
A similar example is runtime code scanning used by full virtualization solutions to find and redirect privileged instructions (to work around issues in certain processor instruction sets).
類似的一個例子是完全虛擬化解決方案通過運行時代碼掃描來查找和重定曏特權指令（用來解決特定処理器指令集的一些問題）。
