Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the examples, which are not intended to limit the present invention.

[0025] Such as figure 1 As shown, the physical devices involved in the virtual machine migration process include: the host machine (physical machine) before the virtual machine migration, the host machine after the virtual machine migration, the remote host and the switch, and the two host machines are connected to the same switch. The remote host sends a data packet to the virtual machine through the switch, and the switch forwards the data packet to the host where the virtual machine is located, and the host uses virtualization technology to send the data packet to the virtual machine. In the "shutdown-restart" phase of the virtual machine, the virtual machine is completely migrated from one host to another. At this time, the switch still sends data packets to the host before the migration before the migration proce...

Abstract

The invention discloses a data flow adaptive system and corresponding adjustment method in a virtual machine migration procedure, which aims to solve a problem of data packet dropout caused by neglect of processing of a data packet subsequently arriving in an original physical machine during ''shutdown-restart'' in the prior art. The system comprises a transmitting end for redirecting the data packet when the virtual machine shuts down, a receiving end for retransmitting the data packet after the virtual machine restarts and a migration mechanism for migrating the data packet between the transmitting end and the receiving end. According to the method provided by the invention, the virtual machine can still process the data packet arriving in the original physical machine after restarting in a new physical machine through sequential combination of the three parts, thereby implementing an effect that the data packet arriving in the virtual machine in the whole migration procedure is nearly lossless and providing a foundation for designing various virtual machine schemes of the upper layer.

Description

technical field [0001] The invention relates to the field of cloud environment deployment, in particular to a data flow adaptive adjustment system and a corresponding adjustment method in the process of virtual machine migration, which belongs to the modification of the migration mechanism. Background technique [0002] In recent years, cloud computing and cloud deployment have made continuous progress in technology, and on this basis, applications and research on various cloud platforms have been derived. Virtualization technology is the basic technology of the cloud platform. After long-term development, there are already many mature virtual machine products. In addition to improving the resource utilization of physical machines as much as possible, the scalability and deployment flexibility brought about by developing virtual machines as much as possible has become a research focus. [0003] Most virtual machine migration implementation plans ignore the processing of sub...
