FIELD: information technology.
SUBSTANCE: invention discloses hierarchical virtualisation, where such virtualisation can be accomplished through a multi-level mechanism. The hierarchical virtualisation includes using a hypervisor which maintains a first partition and using a virtualisation stack in the first partition to create and control a second partition. Multiple virtualisation stacks can exist in the first partition, and each virtualisation stack can create and control multiple partitions. In one particular implementation, a child partition can have exclusive control over part or all of its resources with respect to a parent partition. The hypervisor as the ultimate arbiter in such a virtualised environment enforces such a setup and can communicate directly with any partition in the virtualised hierarchy.
EFFECT: easier hierarchical virtualisation.
