Abstract: A resource configuration method of a virtual machine and a communications device. When an actual requirement of the virtual machine for the network resource is dynamically changed, the communications device may dynamically configure a communication manner corresponding to the virtual machine such that a virtual machine with a relatively low requirement for the network resource may use the manner of sharing the physical network interface card, and a virtual machine with a relatively high requirement for the network resource may use the pass-through manner, which does not cause a situation in which network resources of some virtual machines are wasted and network resources of some virtual machines are insufficient. As a result, network resources of virtual machines are properly allocated.
Abstract translation: 虚拟机和通信设备的资源配置方法。 当网络资源的虚拟机的实际需求动态地改变时，通信设备可以动态地配置对应于虚拟机的通信方式，使得网络资源需求相对较低的虚拟机可以使用共享的方式 物理网络接口卡和对网络资源要求较高的虚拟机可以使用直通方式，这不会导致一些虚拟机的网络资源被浪费的情况和一些虚拟机的网络资源 不够 因此，虚拟机的网络资源被正确分配。

Abstract: A system includes a first subsystem and a second subsystem that are used in a same chip. A security level of a first physical resource included in the first subsystem is higher than a security level of a second physical resource included in the second subsystem. The first subsystem includes an interrupt controller, and the interrupt controller is configured to manage an interrupt of a peripheral of the second subsystem. Embodiments of this application are for isolation between subsystems of different security levels in a chip.

Abstract: Method and systems for executing a non-maskable interrupt are provided. In one aspect, a method for executing a non-maskable interrupt includes: obtaining an interrupt request in a non-secure mode, and interrupting an operation of an operating system (OS); saving, in a secure mode, a status of the OS when the operation of the OS is interrupted; executing, in the non-secure mode, a procedure defined for the interrupt request; resume, in the secure mode, the status of the OS; and after resuming the status of the OS, continue executing the operation of the OS in the non-secure mode.

Abstract: The present invention discloses a method and an apparatus for executing a non-maskable interrupt. The method includes: obtaining a secure interrupt request in a non-secure mode, and interrupting an operation of an operating system OS, where the secure interrupt request cannot be masked; entering a secure mode by using the secure interrupt request, and saving, in the secure mode, an interrupt context of an OS status when the operation of the OS is interrupted; returning to the non-secure mode to execute user-defined processing; after the user-defined processing is completed, entering the secure mode again, and resuming the OS status in the secure mode according to the interrupt context; and returning to the non-secure mode again, and continuing to execute an operation of the OS. The method and the apparatus for executing a non-maskable interrupt in embodiments of the present invention can easily implement an NMI mechanism without depending on hardware.
