METHODS AND ALGORITHMS FOR VIRTUAL MACHINE MIGRATION

The article discusses various aspects of virtual machine migration. The process of moving them between different hosts, data storages, or even between cloud environments. It can be performed in two modes: cold migration, when the virtual machine is previously turned off, and live (dynamic) migration, which occurs without stopping its operation. Thanks to live migration, it is possible to transfer active virtual machines, for example, between servers within a cluster, without interrupting the provision of services. To organize such a process, special administration tools are used, in particular Hyper-V Manager or System Center Virtual Machine Manager from Microsoft Learn.
