Abstract
Embodiment pertain to facilitation of live migration of a virtual machine in a network system. The network system includes a first host, a second host, a first appliance for providing service to the first host, a second appliance for providing service to the second host, and a third appliance. At least one virtual machine is disposed on the first host and has an ongoing first network flow. The first appliance has generated state information about the first network flow. During the migration of the at least one virtual machine to the second host, the third appliance obtains a copy of the state information about the first network flow; and the third appliance takes over from the first appliance to serve the first network flow during the migration of the at least one virtual machine, until the first network flow is terminated.
