Problems solved by technology

[0003] Currently mainstream virtualization technologies include VMware vSphere, Xen, and KVM. During the online migration process, the copy of the virtual machine memory is transmitted in plain text, and the virtual machine memory contains a lot of user data, which may be sensitive. data, in an environment with relatively high security requirements, if the listener places a packet capture tool in the network, it may cause sensitive user data to be intercepted and cause data leakage

Abstract

The invention relates to the technical field of the Internet, in particular to a virtual machine on-line migration process memory data protection method and device and a physical machine. As the source physical machine migrate to the target physical machine, the source physical machine sends the pre-encrypted memory data of the virtual machine, at the same time, the memory change data in the transfer process of the virtual machine is recorded, and the memory change data is encrypted and sent to the target physical machine until the memory change data stops transmission to the target physical machine when the memory change data is very small, so that on the one hand, the data transmission speed is ensured, and on the other hand, the data transmission security is ensured.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method, a device and a physical machine for protecting memory data during online migration of a virtual machine. Background technique [0002] Virtualization is widely used in cloud computing. Online migration of virtual machines is a very important technology in virtualization platforms. It can migrate virtual machines from one physical machine to another without stopping. Services in the virtual machine will not be affected during the process. If the virtual machine on a physical machine may be busy and needs other physical machines to share the load, it is necessary to migrate the virtual machine online, or if there is a physical machine that needs to be maintained, it is also necessary to migrate the virtual machine on the physical machine to on other physical machines. [0003] Currently mainstream virtualization technologies include VMware vSphere, Xen, and...
