内核使用收集的CPU 使用量数据，可以根据优先级、当前 CPU 使用量和 CPU 限制调度或撤消运行进程。
The CPU usage thus gathered is used by the kernel, which may schedule or de-schedule a process based on its priority, current CPU usage, and CPU limits.
操作系统级的虚拟化要求对操作系统的内核进行一些修改，但是其优点是可以获得原始性能。
Operating system-level virtualization requires changes to the operating system kernel, but the advantage is native performance.

为了使这个过程的效率更高，内核使用了一个位图来定义给定优先级列表上何时存在任务。
To make this process more efficient, a bitmap is used to define when tasks are on a given priority list.
最后，在早期的内核中，抢占是不可能的；这意味着如果有一个低优先级的任务在执行，高优先级的任务只能等待它完成。
Finally, preemption wasn't possible in the earlier scheduler; this meant that a lower priority task could execute while a higher priority task waited for it to complete.
操作系统级的虚拟化是一种服务器虚拟化方法，在这种方法中，操作系统的内核支持多个相互隔离的用户空间实例。
