Zusammenfassung:	Mechanisms are provided for performing a live update of an operating system. The mechanisms receive an update to an operating system and clone a 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. The mechanisms apply the update to the cloned root volume group to generate an updated and cloned root volume group and boot a second logical partition of the data processing system using the updated and cloned root volume group. Moreover, the mechanisms mirror the original root volume group associated with an operating system instance executing in a first logical partition and import the mirrored root volume group into the second logical partition. The mechanisms migrate application instances to the second logical partition by restarting the application instances in the second logical partition using the mirrored root volume group.
