Abstract: Embodiments can provide a smart interface card control method and apparatus. Under such a method or apparatus, after a smart interface card is inserted into a smart interface card slot of a host, a virtualized management interface can be registered with the host using a protocol stack of a preset type. A virtual link can be created to connect a baseboard management controller management interface to the virtual link. A management address configuration instruction sent by the host can be received for configuring a management address of the management interface. A control instruction sent by the host by using the management address can be received, and the control instruction to the BMC management interface can be sent by using the virtual link. According to the foregoing smart interface card control method and apparatus, scalability of the smart interface card can be improved.

Abstract: A data processing method includes receiving, by a virtual machine, an I/O access request. The I/O access request is used to access data, the I/O access request includes a type of hardware data used to indicate a working status of a virtual I/O device, and the virtual I/O device is obtained after the I/O device is virtualized. The method also includes identifying, by the virtual machine, that the type of the hardware data in the I/O access request is first-type data. The first-type data is hardware data of the virtual I/O device that remains unchanged in a data processing process. The method further includes obtaining, by the virtual machine, to-be-accessed data from a first memory space. The first memory space is memory storage space in the data processing system.
