Abstract
The present document discloses a method and system for realizing virtual machine mobility, comprising: in a process of establishing communication with a second virtual machine, a first virtual machine subscribing to a media access control (MAC) address change notification of the second virtual machine from an address resolution server (ARS) through a first virtual switch in a physical server where the first virtual machine is located; after the second virtual machine migrates, a second virtual switch in a physical server, to which the second virtual machine migrates, registering a corresponding relationship between an IP address of the second virtual machine and a MAC address of the second virtual switch itself to the ARS; and the ARS updating the MAC address corresponding to the IP address of the second virtual machine, and notifying the first virtual machine of the updated MAC address according to the subscription of the first virtual machine.
