Problems solved by technology

Virtual machine migration needs to copy the virtual machine memory on the source VMM (virtual machine monitor) to the target VMM and continue the operation of the virtual machine. This process needs to consume network bandwidth. For the environment with a large number of machines in the data center, a large number of virtual machine migration Great pressure on network bandwidth

Abstract

The invention discloses a memory redundancy oriented virtual machine migration device and method, wherein the method comprises the following steps: integrating the characteristics of a virtual machine with memory data redundancy by using a data center, and before the virtual machine is subjected to formal migration, scanning a memory page of the virtual machine so as to obtain a memory descriptor of the virtual machine which is required to be migrated; comparing the obtained memory descriptor with a targeted-node memory page so as to obtain part of memory page list of the virtual machine which is required to be migrated; and according to the obtained memory page list, canceling the transmission of redundant memories, and reducing the transmission quantity of data for migration by using a data compression technology. Therefore, by using the device and method disclosed by the invention, in the process of virtual machine migration with the purpose of saving the memory resources of the data center, the network load can be reduced as far as possible, and the overall resource utilization ratio of the data center can be improved.

Description

(1) Technical field [0001] The present invention relates to a memory redundancy-oriented virtual machine migration device and method thereof. The memory redundancy information on the source host machine and the target host machine is used to reduce the memory copy in the process of virtual machine migration, thereby increasing the migration speed. The invention relates to reducing network traffic, belonging to the field of computer technology. (2) Background technology [0002] There are tens of thousands of servers in the current data center, some of these data centers only run a single program of a certain company, and some data centers rent out huge computing resources and storage resources to customers, this method is called cloud calculate. With the popularity of cloud computing, more and more web services and business applications are deployed in cloud computing, and at the same time, the data centers carrying cloud computing are getting larger and larger. For the ma...
