Mobility validation by trial boot using snap shot

摘要

An approach is provided for migrating a live instance of a virtual machine from a source computer system to a target computer system. The approach operates by creating a consistent snap shot image of an operating system environment that is running the live instance of the virtual machine on the source computer system. A test virtual machine container is created based on an actual virtual machine container that corresponds to the live instance of the virtual machine. Based on the snap shot image of the operating system environment, a test virtual machine is created in the test virtual machine container. The generated test virtual machine is tested with a migration of the live instance of the virtual machine being performed in response to a successful test of the test virtual machine. The migration is aborted in response to an unsuccessful test of the test virtual machine.

主权项

1. A method of migrating a live instance of a virtual machine from a source computer system to a target computer system, wherein the live instance of the virtual machine is managed by a hypervisor, the method comprising:
creating a consistent snap shot image of an operating system environment that is running the live instance of the virtual machine on the source computer system; creating a test virtual machine container based on an actual virtual machine container corresponding to the live instance of the virtual machine; generating, based on the snap shot image of the operating system environment, a test virtual machine in the test virtual machine container; testing the generated test virtual machine, wherein a migration of the live instance of the virtual machine is performed in response to a successful test of the test virtual machine; and inhibiting commencement of the migration in response to an unsuccessful test of the test virtual machine.
