Abstract
Some embodiments provide a novel method of migrating a particular virtual machine (VM) from a first host computer to a second host computer. The first host computer of some embodiments has a physical network interface card (PNIC) that performs at least one of network forwarding operations and middlebox service operations for the particular VM. The first host computer sends, to the PNIC of the first host computer, a request for state information relating to at least one of network forwarding operations and middlebox service operations that the PNIC performs for the particular VM. The first host computer receives the state information from the PNIC. The first host computer provides the state information received from the PNIC to the second host computer as part of a data migration that is performed to migrate the particular VM from the first host computer to the second host computer.
