US 2019/0095243 A1 · Virtual Machine Migration Method and Apparatus, and Virtualization System

Abstract

A method and an apparatus for migrating a virtual machine across virtualization systems, and a system, where a first virtualization system in which a source virtual machine is located specifies a temporary address of a destination virtual machine. After a second migration tool of a second virtualization system migrates the to-be-migrated virtual machine to the second virtualization system to generate the destination virtual machine, a first migration tool of the first virtualization system controls a migration agent on the destination virtual machine to modify the address of the destination virtual machine to an address of the source virtual machine such that the address of the virtual machine remains unchanged before and after migration, thereby shortening service interruption duration caused by virtual machine migration.

Dependent claims

A method for migrating a virtual machine in a virtualization environment, comprising:

instructing, by a first migration tool of a first virtualization system, a second migration tool of a second migration system to migrate a source virtual machine comprising a first migration agent to generate a destination virtual machine corresponding to the source virtual machine on a host of a second virtualization system, the source virtual machine being a to-be-migrated virtual machine in the first virtualization system, an address of the destination virtual machine being a temporary address, the temporary address being configured by the first migration tool and is different from an address of the source virtual machine, and the destination virtual machine comprising the first migration agent;
establishing, by the first migration tool, a coupling to the first migration agent in the destination virtual machine;
and
instructing, by the first migration tool, the first migration agent to modify the address of the destination virtual machine to the address of the source virtual machine.

A first virtualization system, comprising:

a first migration agent;
and
a first migration tool coupled to the first migration agent and configured to instruct a second migration tool of a second migration system to migrate a source virtual machine comprising the first migration agent to generate a destination virtual machine corresponding to the source virtual machine on a host of a second virtualization system, the source virtual machine being a to-be-migrated virtual machine in the first virtualization system, an address of the destination virtual machine being a temporary address, the temporary address being configured by the first migration tool and is different from an address of the source virtual machine, and the destination virtual machine comprising the first migration agent, the first migration agent on the destination virtual machine being configured to establish a coupling to the first migration tool, the first migration tool being further configured to instruct the first migration agent to modify the address of the destination virtual machine to the address of the source virtual machine, and the first migration agent on the destination virtual machine being further configured to modify the address of the destination virtual machine to the address of the source virtual machine.

A virtual machine migration apparatus, comprising:

a memory storing a program instruction;
and
a processor coupled to the memory, the program instruction causing the processor to be configured to:
instruct a second migration tool of a second migration system to migrate a source virtual machine comprising a first migration agent to generate a destination virtual machine corresponding to the source virtual machine on a host of a second virtualization system, the source virtual machine being a to-be-migrated virtual machine in a first virtualization system, an address of the destination virtual machine being a temporary address, the temporary address being configured by the virtual machine migration apparatus and is different from an address of the source virtual machine, and the destination virtual machine comprising the first migration agent;
establish a coupling to the first migration agent in the destination virtual machine;
and
instruct the first migration agent to modify the address of the destination virtual machine to the address of the source virtual machine.
