Abstract
Embodiments perform migration-aware load balancing in virtual data centers. One or more load balancing modules in a host distribute data requests from clients to one or more servers implemented as virtual machines (VMs). The load balancing modules are notified of VM migration (e.g., live migration) prior to the VM migration and reduce the load on the VM to be migrated. After being notified of completion of VM migration, the load balancing modules increase the load on the migrated VM. Such migration notifications enable the load balancing modules to prevent or reduce performance degradation and migration duration, among other aspects.
