Linux

XtratuM 1.0 was initially designed initally as a substitution of the RTLinux to achieve temporal and spatial requirements. XtratuM was designed as a nanokernel which virtualises the essential hardware devices to execute concurrently several OSes, being at least one of these OSes a RTOS.

After this initial design, XtratuM was designed from scratch again to be a hypervisor type 1.

Linux has been ported (para-virtualised) to be executed as a XtratuM partition offering
full functionalities.

Several Linux partitions can be executed on top of XtratuM.
