Abstract
Some embodiments of the invention provide a method for migrating a machine on a first host computer to a second host computer. At the first host computer, the method gathers a set of service insertion data used by a first service insertion module executing on the first host computer to identify a particular chain of multiple services that a set of multiple service nodes have to perform on a particular data message flow associated with the machine. To the second host computer, the method sends a set of machine configuration data and the set of service insertion data. The second host computer (1) uses the machine configuration data to deploy the machine on the second host computer and (2) uses the gathered set of service insertion data to configure a second service insertion module executing on the second host computer to identify the particular chain of two or more services.
