Problems solved by technology

[0003] In the cloud network, users use virtual machines, such as: cloud server (Elastic ComputeService, referred to as ECS), its network card is usually realized by software virtualization, and does not have the full name of remote direct memory access (Remote Direct Memory Access) of hardware network card. Access, referred to as RDMA) capabilities; secondly, the current cloud network is usually based on the private cloud (Virtual Private Cloud, referred to as VPC) network implemented by the overlay network, which cannot use the traditional RDMA technology; finally, due to the network virtualization in the cloud network , the user's network does not want to be limited by the topology of the physical network, and traditional RDMA's perception of the physical network is very important

Abstract

Embodiments of the present invention provide a method, device and equipment for hot migration based on remote direct data storage. The hot migration method includes: acquiring a hot migration request, the hot migration request including: a virtual machine to be migrated; generating a relay route corresponding to the virtual machine to be migrated based on the hot migration request; A hot migration operation of the virtual machine to be migrated. In the technical solution provided by this embodiment, the live migration operation of the virtual machine to be migrated is performed through the relay route, so that the RDMA access of other physical machines to the current physical machine undergoing the live migration operation is not interrupted, and the RDMA data is not lost, allowing users to No perception.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method, device and equipment for thermal migration based on remote direct data storage. Background technique [0002] Hot migration (also known as live migration, live migration), that is, virtual machine save (save) / restore (restore): the entire running state of the entire virtual machine is preserved, and at the same time, it can be quickly restored to the original hardware platform or even different hardware on the platform. After recovery, the virtual machine still runs smoothly, and the user will not notice any difference. [0003] In the cloud network, users use virtual machines, such as: cloud server (Elastic ComputeService, referred to as ECS), its network card is usually realized by software virtualization, and does not have the full name of remote direct memory access (Remote Direct Memory Access) of hardware network card. Access, referred to as RDMA...
