FIELD: computer engineering.
SUBSTANCE: claimed result is achieved due to implementation of virtual devices migration method with preservation of their dynamic state, which consists in the fact that migrating virtual devices from a first virtual machine operating in active mode on a first node to a second virtual machine running in standby mode on a second node, and comprising steps of: creating a data transmission channel between a first virtual device of a first virtual machine and a first hypervisor on a first node, storing a dynamic state of a first virtual device on a first node, transmitting data on state of first virtual device to first hypervisor on first node, transmitting data on state of first virtual device to second hypervisor on second node, creating a data transmission channel between a second virtual device of a second virtual machine and a second hypervisor on a second node, receiving data on state of first virtual device from second hypervisor on second node, restoring data on the state of the first virtual device on the second virtual device.
EFFECT: provision for preservation of dynamic state of virtual devices during their migration.
