MANAGING NIC-ENCRYPTED FLOWS FOR MIGRATING GUESTS OR TASKS

An example of a system and method implementing a live migration of a guest on a virtual machine of a host server to a target server is provided. For example, a host server may utilize a flow key to encrypt and decrypt communications with a target server. This flow key may be encrypted using a receive master key, which may result in a receive token. The receive token may be sent to the Network Interface Controller of the host server, which will then encrypt the data packet and forward the information to the target server. Multiple sender schemes may be employed on the host server, and various updates may take place on the target server as a result of the new location of the migrating guest from the host server to the target server.
