Multi-component consent-based virtual machine migration

摘要

A system, method, and computer program product for controlling migration of a VM operable on a first site and a second site. The system includes an identify component for identifying the second site; a request component for sending a consent request message to a software component, wherein the consent request message comprises at least one of an identifier of the VM and an identifier of the second site; a calculate component, operable on the software component and responsive to receiving the consent request message, for determining consent for the second site; a send component, responsive to a positive determination, for sending a consent message; and a migrate component, responsive to receiving the consent message, for migrating the VM from the first site to the second site.

1. A method for controlling migration of a first virtual machine (VM) from a first site to a second site, the method comprising:
a data processing system identifying the second site as a target site to which the first VM can be migrated; in response to identifying the second site as a target site, the data processing system sending a consent request message to a plurality of software components including multiple VMs running on the second site, wherein the multiple VMs running on the second site include a second VM on which a user application executes with which a client program running on a remote workstation interacts, wherein the consent request message includes at least one of a set including an identifier of the first VM and an identifier of the second site; the data processing system receiving a migration requirement imposed by one of the plurality of software components on migration of the first VM; and in response to receiving consent messages indicating consent of the plurality of software components including all of the multiple VMs to the migration, the data processing system initiating migration of the first VM from the first site to the second site; wherein the data processing system migrates the first VM from the first site to the second site in response to satisfying the migration requirement.
