Abstract
Embodiments of the invention relate to synchronizing multicast groups of a virtual machine during migration of the virtual machine. A first list and a second list, indicating multicast groups corresponding to the first port and second port respectively, are obtained in response to detection of migration of the virtual machine from a first port to a second port of a same switch. The second list is updated so that the second list contains the multicast groups in the first list. An undesired multicast group is aged. Multicast groups of a virtual machine may be synchronized in the process of migration of the virtual machine, thereby reducing or removing the time during which the virtual machine multicast service is disrupted.
