摘要： The present disclosure relates to information processing methods, physical machines, and peripheral component interconnect express (PCIE) devices. In one example method, a PCIE device receives, in a live migration process of a to-be-migrated virtual machine (VM), a packet corresponding to the to-be-migrated VM, where the to-be-migrated VM is one of a plurality of VMs. The PCIE device determines a direct memory access (DMA) address based on the packet. The PCIE device sends the DMA address to a physical function (PF) driver.

摘要： Example virtual machine live migration methods and apparatus are described. In one example method, a first virtual machine which runs on a source server is migrated to a destination server. The source server includes a single-root input/output virtualization (SR-IOV) network adapter. The virtual machine manager delivers a live migration command to the live migration module. The live migration module obtains, according to the live migration command, information that needs to be migrated and that is about the first virtual machine, and reports the information to the virtual machine manager, where the information includes state information of the first virtual network adapter and memory data of the first virtual machine. The virtual machine manager sends the state information and the memory data of the first virtual machine to the destination server.

摘要： A packet processing method and device are provided, to save CPU resources consumed by parsing a packet. The method includes: parsing, by an intelligent network interface card, a received first packet to obtain an identifier of the first packet; updating, by the intelligent network interface card, a control field of a first memory buffer based on the identifier of the first packet; storing, by the intelligent network interface card, a payload of the first packet or a packet header and a payload of the first packet into the first address space through DMA based on an aggregation position of the first packet; aggregating, by a host, the first address information and at least one piece of second address information based on an updated control field in the first mbuf; and reading, by a virtual machine, address information, to obtain data in an address space indicated by the address information.
