Abstract: 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.
