Claim:
1. A method, in a data processing system comprising a processor and a memory, for performing a live update of an operating system, the method comprising: receiving an update to an operating system; cloning an original root volume group associated with an operating system instance executing in a first logical partition of the data processing system to generate a cloned root volume group for booting a second logical partition of the data processing system; mirroring the original root volume group associated with the operating system instance executing in the first logical partition of the data processing system to generate a mirrored root volume group in the first logical partition, wherein modifications to the original root volume group are mirrored to the mirrored root volume group; applying the update to the cloned root volume group to generate an updated and cloned root volume group; booting the second logical partition of the data processing system using the updated and cloned root volume group without shutting down and restarting the data processing system; importing the mirrored root volume group into the booted second logical partition; and migrating application instances to the booted second logical partition by restarting the application instances in the booted second logical partition using the mirrored root volume group.
