Abstract: 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.
