Partitioned software architectures represent the future of secure systems. They have evolved to fulfill security and avionics requirements where predictability is extremely important. The idea behind a partitioned system is the virtualization. A virtual machine (VM) is a software implementation of a machine that executes programs like a real machine. A Hypervisor is a layer of software that enables to run several independent execution environments or partitions in a single computer.
There exists several virtualization solutions targeting specific application needs ranging from general purpose virtualization to embedded systems virtualization, one of them is the XtratuM hypervisor. XtratuM is an open source hypervisor specially designed for real-time embedded systems. It provides a framework to run several operating systems in a robust partitioned environment ensuring strong temporal and spatial isolation properties.
In this paper we present the porting of the Linux general purpose operating system (GPOS) to be run on top of the XtratuM hypervisor. The paper discusses in detail the challenges that have been overcome to run Linux as a XtratuM partition, focusing on solving the memory and device management and initialization process issues that appear when running Linux GPOS under the strong isolation provided by the XtratuM Hypervisor. This development enables XtratuM to be used in a large variety of fields and widens the scope of application of this hypervisor to more generic systems with softer real-time constraints.
