Abstract
Some embodiments of the invention provide a method of migrating a VM from a first host computer to a second host computer, the first host computer having a first PNIC that performs at least one of network forwarding operations and middlebox service operations for the VM. At an RDMA client executing on a set of one or more processors of the first host computer, the method directs an RDMA server executing on the first PNIC to provide networking state data associated with at least one of network forwarding operations and middlebox service operations that the first PNIC performs for the VM. The provided networking state data resides in a memory of the first PNIC that is accessible to the RDMA server. At the RDMA client, the method provides the obtained networking state data to the second host computer as part of a data migration that is performed to migrate the VM from the first host computer to the second host computer.
