Problems solved by technology

The introduction of virtualization along with management and service plane separation has produced a new important problem.
These include the increase in load of the system currently hosting the VM, the occurrence of a fault in the host system, and the temporary unavailability of the system for hosting a VM due to routine maintenance.
Specifically, if a virtual machine migrates, the associated units of manageability need to move as well, where the problem extends to more than simply moving code.
However, there has been no such infrastructure for an autonomic element, which applies specifically to the system management domain where virtual machines are under management.
In particular there is no effective mechanism for transferring a VM from one host to another on which it can resume operation seamlessly.

Embodiment Construction

[0037]To facilitate the understanding of the present invention, a reference is made herein to the previously filed applications of Embotics Corporation, all of which are incorporated herein by reference:

[0038]Canadian patent applications serial numbers 2,435,655 and 2,475,387 to Shannon et al, both entitled “Embedded System Administration”; and

[0039]Canadian patent applications serial numbers 2,504,333 and 2,543,938 to White et al, both entitled “Programming and Development Infrastructure For An Autonomic Element”.

[0040]The present invention focuses on systems that use autonomic computing principles to manage virtual machines in a scenario where management and service are separated in distinct execution environments, also referred to as management and service planes respectively. A single management plane may provide manageability for one or more service planes. The invention provides a method and system for VM migration, and the infrastructure to support the mobility of manageabili...

Abstract

Virtual machine (VM) technology allows multiple operating systems each deploying multiple applications to run on a single host. This invention presents an effective method and system for virtual machine migration from a source host to a target host. The method and system concern the migration of both the service VM and the element managing it. State of the migrating VM is preserved so that it can resume its execution on the target host.

Description

RELATED APPLICATIONS[0001]The present patent application claims priority from the Canadian patent application serial number 2,547,047 to Anthony WHITE entitled “MANAGEMENT OF VIRTUAL MACHINES USING MOBILE AUTONOMIC ELEMENTS” filed on May 15, 2006, which is incorporated herein by reference.FIELD OF INVENTION[0002]The present invention relates to the management of virtual machines, and particularly to the management of virtual machine migration from one host system to another by using mobile autonomic elements.BACKGROUND OF THE INVENTION[0003]The drive to make more effective use of physical resources within an enterprise information technology (IT) infrastructure has led to the introduction of virtual machine technology. Virtual machine (VM) technology allows one or more guest operating systems to run concurrently on one physical device. There are several approaches to providing virtualization technology, the most recent being para-virtualization and native central processing unit (CP...
