System/390 架构支持机器的完全虚拟化，甚至包括只能在为虚拟机创建的沙箱中运行的“特权”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.
类似的一个例子是完全虚拟化解决方案通过运行时代码扫描来查找和重定向特权指令(用来解决特定处理器指令集的一些问题)。
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).
一旦你习惯于许多的外部指令，当你可以完全掌控自己时间的时候，推动自己去做某事将会是很困难的。
If you're used to having a lot of external direction, it can be really tough to motivate yourself when you're totally in charge of your own time.
