Title: METHOD AND APPARATUS FOR DETERMINING VIRTUAL MACHINE MIGRATION
Abstract:
Provided are a method and apparatus for determining virtual machine (VM) migration. The method comprises: after a VM migrates, sending a free ARP message or RARP message to a migrated VTEP device; the VTEP device acquiring an MAC address of the VM, searching for an ARP Cache table according to the MAC address, and acquiring an IP address of the VM; and constructing an ARP unicast request message by means of taking the IP address as a destination IP address, and if the VTEP device receives an ARP response message, sent by the VM, for the ARP unicast request message, determining that the VM migrates. According to the method provided in the embodiments of the present invention, when a VM migrates, a device to which the VM migrates can determine that the VM migrates by means of only acquiring an MAC address of the VM. The device migrated to is not limited to sense the migration of a VM by means of the virtual machine sending a free ARP message, thereby effectively improving the compatibility for a virtual machine configuration.
