Abstract
One embodiment discloses a method and apparatus for synchronizing IP information of virtual machines. The method includes: obtaining an IP relevant message of at least one virtual machine within a subnet, recording IP information and connection information of the at least one virtual machine based on the IP relevant message, and modifying connection information of a specific virtual machine in response to migration of the specific virtual machine. The apparatus corresponds to the method. With the method and apparatus above, IP information and connection information of respective virtual machines within the subnet are recorded regularly and routinely. Once a certain virtual machine is migrated, updating and modifying connection information of the migrated virtual machine is only needed, but without a need for resending a request to the Dynamic Host Configuration Protocol (DHCP) server. Thus, network disruptions caused by non-synchronization of IP information when the virtual machine is migrated are avoided.
