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