Emulation also commonly interprets the instructions of the guestVM (compared to virtualization, where the instruction set architecture of the guests must be the same as the host).
仿真还常常解释来宾vm的指令(与虚拟化相比，此处来宾的指令集架构必须与主机相同)。

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。

Virtualization has been implemented in networking stacks for quite some time to permit VMguest networking stacks access to the host networking stack.
