XtratuM is a hypervisor based on para-virtualisation that provides one or more virtual execution environments for partitions. A partition is an execution environment managed by the hypervisor which uses the virtualised services. Each partition consists of one or more concurrent processes (implemented by the operating system of each partition), that share access to processor resources based upon the requirements of the application. The partition code can be:
Partitions need to be virtualised to be executed on top of a hypervisor. Depending on the underlaying hardware, XtratuM provides:
