A controller of a network control system for configuring several middlebox instances is described. The middlebox instances implement a middlebox in a distributed manner in several hosts. The controller configures, in a first host, a first middlebox instance to receive a notification from a migration module before a virtual machine (VM) running in the first host migrates to a second host and to send middlebox state related to the VM to the migration module.
