Regardless of whether the device emulation occurs in the hypervisor or on top in a guest virtual machine (VM), the emulation methods are similar.

无论设备模拟发生在管理程序内还是在一个客户虚拟机(VM)之上，模拟方法都是相似的。

This model USES a virtual machine that mediates between the guest operating systems and the native hardware (see Figure 2).

这种模型使用一个虚拟机，它在客户操作系统和原始硬件之间进行协调(参见图2)。
