Embodiment Construction

[0018] The technology generally involves migrating a guest of a virtual machine from a host server to a target server while avoiding loss of connectivity and continuing to encrypt data accurately. For example, a virtual machine on a host server may need to be migrated to a target server. In this case, the monitor associated with the host server may cooperate between the client server and the network interface controller (NIC) and ultimately the target server.

[0019] The host server can use the stream key to encrypt and decrypt communications between the host server and the target server. When it comes to migrating clients, the stream key can be encrypted by receiving the master key, which can generate the receiving key. As an example, this process can occur on a monitor of a host server. The monitor can then send the receive token (along with the stream key encapsulated therein) to the host server's NIC. The NIC then encrypts the data packet using the stream key, and send...

Abstract

A system and method are provided for implementing live migration of clients on virtual machines of a host server (110) to a target server (150). For example, the host server (110) can encrypt and decrypt communications with the target server (150) using a stream key. The stream key can be encrypted (808) with the receive master key, which results in a receive token. The receipt token may be sent (810) to the network interface controller (120) of the host server (110), which then encrypts the data packet and forwards the information to the target server (150). Multiple sender scenarios can be employed on the host server (110) and various updates can occur on the target server (150) as a result of the new location of the client being migrated from the host server (110) to the target server (150) result.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation of U.S. Patent Application No. 14 / 708,685, filed May 11, 2015, which claims the application titled "Managing NIC Encrypted Streams for MANAGINGNIC-ENCRYPTED FLOWS FOR MIGRATING GUESTS OR TASKS," U.S. Provisional Patent Application No. 61 / 991,784, which is hereby incorporated by reference in its entirety. Background technique [0003] Migration of a client on a virtual machine (VM) from a host server to a target server may affect not only the location of data, but also various external computing devices that interact with the client as well as the server. Technological advances have resolved some of the issues associated with native migrations, which can effectively suspend customer execution until the migration is complete. In this regard, brownout and blackout phases can be employed to reduce the client's abort time such that the only abort is during the outage phase to deliver dirty...
