Abstract:
1. A system, comprising: a processor; logic executable by the processor to: create, in a host machine running an instance of a first version of an operating system, a first workload partition associated with a second version of the operating system, the second version of the operating system comprising a different version of the operating system than the first version of the operating system; mount a first root file system and a user file system for the first workload partition, the first root file system comprising management information for managing the first workload partition; create, in the host machine, a second workload partition associated with the second version of the operating system; mount a second root file system for the second workload partition, the second root file system comprising management information for managing the second workload partition; and hierarchically link the second workload partition to the first workload partition to enable sharing of resources of the first workload partition by the second workload partition, the second workload partition sharing the user file system from the first workload partition, and wherein the user file system of the first workload partition remains mounted while the second workload partition is active.
