1. A method comprising:
after a virtual machine (VM) is migrated from a source device to a target device, obtaining, by the target device, a media access control (MAC) address of the VM from a local interface, and
perceiving, by the target device, that the VM is migrated, based on a same MAC address having been received from the source device;
probing by the target device, in response to the perceiving that the VM is migrated, by the target device, the VM by sending an address resolution protocol (ARP) request packet to the VM based on the MAC address of the VM;
receiving, by the target device, an ARP response packet from the VM.
