Abstract: This application provides an IO request processing method, used in an external device. The external device includes a processor and a first hardware interface, and the first hardware interface is an interface that supports a PCIe protocol. The external device communicates with a physical host through the first hardware interface. The method includes: The processor synchronizes, through the first hardware interface, queue information in storage space of a virtual machine running on the physical host to storage space of the external device, where the queue information includes one or more input/output IO requests; and the processor sends the one or more IO requests to a storage server or a network server for processing. According to this application, all hardware resources of the physical host can be used to provide virtual machine services for users, thereby improving utilization of hardware resources of the physical host.

Abstract: This application provides a method for migrating a virtual machine and an apparatus. The method is applied to a source-end physical host, the source-end physical host includes a host machine operating system and a source-end virtual machine running in the host machine operating system, and the host machine operating system includes a PF driver. According to the technical solutions of this application, memory consistency, before and after a migration process, of a virtual machine configured with a pass-through device can be ensured.
