A system for virtual machine live migration includes a management node, a source server, a destination server, a PCIE switch, and an SR-IOV network adapter, where the source server includes a VM before live migration; the destination server includes a VM after live migration; the source server, the destination server, the management node, and the SR-IOV network adapter separately connect to a physical port of the PCIE switch to perform communication; the management node is adapted to configure, by using the PCIE switch, a connection relationship between a VF module used by the VM before live migration and the source server as a connection relationship between the VF module and the destination server; and the destination server, by using the PCIE switch and according to the connection relationship with the VF module configured by the management node, uses the VF module to complete virtual machine live migration. By switching the connection relationships, the system ensures that a data packet receiving and sending service is not uninterrupted, thereby ensuring continuity of a network service. |
