12 Facts About Embedded hypervisor

An embedded hypervisor is a hypervisor that supports the requirements of embedded systems.

Requirements for an embedded hypervisor are distinct from hypervisors targeting server and desktop applications.

An embedded hypervisor is designed into the embedded device from the outset, rather than loaded subsequent to device deployment.

The use of virtualization and its implementation in the form of a hypervisor in embedded systems are very different from enterprise applications.

An embedded hypervisor is most often a type 1 hypervisor which supports the requirements of embedded systems development.

An embedded hypervisor typically provides multiple VMs, each of which emulates a hardware platform on which the virtualised software executes.

Embedded hypervisor systems are typically highly resource constrained due to cost and technical limitations of the hardware.

One of the most important functions required in an embedded hypervisor is a secure message-passing mechanism, which is needed to support real-time communication between processes.

An embedded hypervisor needs to be in complete control of system resources, including memory accesses, to ensure that software cannot break out of the VM.

An embedded hypervisor is able to provide secure encapsulation for any subsystem defined by the developer, so that a compromised subsystem cannot interfere with other subsystems.

An embedded hypervisor makes it possible to restrict access by other system software components to a specific part of the system containing IP that needs to be protected.

The embedded hypervisor can provide an isolated execution environment for proprietary software sharing the processor with open source software subject to the GPL.
