Abstract: A plurality of virtual domains are isolated from one another by a virtual machine monitor (VMM), the plurality of virtual domains including a first guest domain and a privileged domain. Peripheral related instructions are isolated from the first guest domain. The privileged domain is to cause execution of the peripheral related instructions, where the peripheral related instructions upon execution validate a type of the peripheral device.

Abstract translation: 多个虚拟域通过虚拟机监视器（VMM）彼此隔离，多个虚拟域包括第一来宾域和特权域。 外围相关指令与第一个访客域隔离。 特权域是执行外围设备相关指令，其中执行时的外围设备相关指令验证外围设备的类型。

Abstract translation: 多个虚拟域通过虚拟机监视器（VMM）彼此隔离，所述多个虚拟域包括第一来宾域和特权域。 外围相关指令与第一个访客域隔离。 特权域是执行外围设备相关指令，其中执行时的外围设备相关指令验证外围设备的类型。
