Abstract: Embodiments of this application provide a method and an apparatus for determining virtual machine VM migration. The method includes: after a VM is migrated, sending a gratuitous ARP packet or a RARP packet to an in-migration VTEP device; obtaining, by the VTEP device, a MAC address of the VM, searching an ARP cache table based on the MAC address, and obtaining an IP address of the VM; and constructing an ARP unicast request packet by using the IP address as a destination IP address, and if the VTEP device receives an ARP response packet sent by the VM for the ARP unicast request packet, determining that the VM is migrated.
