A virtual machine migration method and device

Abstract

The invention discloses a virtual machine migration method, comprising: obtaining a first virtual machine list, the first virtual machine list including the Internet protocol IP address of the virtual machine in the target subnet; according to the IP address, from the first A second virtual machine list is filtered out from the virtual machine list, and the second virtual machine list includes all virtual machines in the first virtual machine list that have not obtained actual IP addresses; for the virtual machines in the second virtual machine list The virtual machine allocates a logical IP address, and the logical IP address is an IP address different from the actual IP address in the first virtual machine list in the target subnet; according to the allocated logical IP address, the virtual machine in the second virtual machine list Create a virtual network server resource; when the actual IP address of the virtual machine in the second virtual machine list is resolved, replace the logical IP address of the corresponding virtual machine in the virtual network server with the actual IP address. The invention also discloses a virtual machine migration device at the same time.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a virtual machine migration method and device. Background technique [0002] The virtualization platform VMware's virtualization technology enables users to confidently virtualize any application, redefines availability and simplifies virtual data centers, and ultimately achieves a highly available and resilient on-demand infrastructure. The virtualization product vCenter Server can provide unified management for the entire virtual infrastructure, and can realize many functions of the key virtualization platform vSphere, such as real-time migration. Moreover, the virtualization product vCenter Server can manage thousands of virtual machines distributed in multiple locations, using rapid provisioning and automated policies to streamline the management process. [0003] In order to provide flexible and scalable cloud computing for public or private clouds of virtual computing or sto...

Problems solved by technology

[0006] Although the above-mentioned patent introduces a virtual machine migration method, this method does not describe in detail the configuration information of the virtual machine obtained during the migration process, but assumes that under ideal circumstances, the network configuration information of the virtual machine can be normal Obtain

In practical applications, if the virtual machine is not installed with the virtual machine tool VMware Tools, or is in the shutdown state, the IP address information of the virtual machine cannot be obtained by calling the Simple Object Access Protocol (SOAP, Simple Object Access Protocol) API of the virtualization platform VMware. In the process of migrating the virtual machine to OpenStack, the virtual machine cannot be migrated to the OpenStack management platform due to the lack of IP address information

Furthermore, each network of OpenStack provides available IP address resources. During the process of migrating a virtual machine from the virtualization platform VMware environment to openstack, if the IP address information of the virtualization platform VMware cannot be obtained, OpenStack It is impossible to assign an IP address to the virtual machine, which affects the creation of the virtual machine

[0007] It can be seen that in order to solve the problem that the virtual machine cannot be migrated to the OpenStack management platform due to the lack of IP address information, it is urgent to find a virtual machine migration solution
