The OKL4 microvisor

Gernot Heiser, Ben Leslie
2010 Proceedings of the first ACM asia-pacific workshop on Workshop on systems - APSys '10  
It is also a third-generation microkernel that aims to support the construction of similarly componentised systems as classical microkernels.  ...  We argue that recent hypervisor-vs-microkernel discussions completely miss the point. Fundamentally, the two classes of systems have much in common, and provide similar abstractions.  ...  The microkernel is supposed to be general enough to support the construction of arbitrary systems on top.  ...

Joshua LeVasseur, Volkmar Uhlig, Yaowei Yang, Matthew Chapman, Peter Chubb, Ben Leslie, Gernot Heiser
2008 2008 13th Asia-Pacific Computer Systems Architecture Conference  
We demonstrate soft layering on x86 and Itanium: we can load a single Linux binary on a variety of hypervisors (and thus substitute virtual machine environments and their enhancements), while achieving  ...  These limitations are accepted as inevitable for significantly better performance, and for the ability to provide virtualization-like behavior on non-virtualizable hardware such as x86.  ...  L4 microkernel back-end: The L4 API is a set of portable microkernel abstractions, and is thus high-level.  ...

A survey of customizability in operating systems research

G. Denys, F. Piessens, F. Matthijs
2002 ACM Computing Surveys  
An important goal of an operating system is to make computing and communication resources available in a fair and efficient way to the applications that will run on top of it.  ...  The design of the library is unrestricted; the microkernel does not impose any paradigm at all for the construction of services on a higher level.  ...  Two systems, Fluke and EROS, are capability systems structured around a microkernel. Fluke's architecture combines a microkernel with virtual machines.  ...

1991 Computer Communications  
In Sec. 3 we will begin our discussion of Amoeba itself, starting with the microkernel.  ...  However, some users will want to run massively parallel programs, and will not be able to harness all the idle CPU cycles because they are in other users' personal machines.  ...  In this section we will describe the microkernel.

T-Visor: A Hypervisor for Mixed Criticality Embedded Real-time System with Hardware Virtualization Support [article]

Takumi Shimada, Takeshi Yashiro, Ken Sakamura
2018 arXiv   pre-print
However, as most of existing hypervisors are designed for general-purpose information processing systems, they rely on large system stacks, so that they are not suitable for mixed criticality embedded  ...  DOI: 10.1145/1235 Basically, these are used for running multiple virtual machines (VMs) on one physical machine. In the cloud systems, providers lend their VMs to multiple tenants.  ...  Unikernels are designed to run on hypervisors, so that they employ virtual devices. This makes unikernels portable between different hardwares.  ...

A message-driven programming system for fine-grain multicomputers

Daniel Maskit, Stephen Taylor
1994 Software, Practice & Experience  
This machine combines a unique collection of architectural features that include fine-grain processes, on-chip associative memory; and hardware support for process synchronization.  ...  These tools operate in conjunction with a run-time microkernel. The microkernel uses the hardware associative cache to keep track of what code is present at a single computer.  ...  Although some aspects of these concepts have been found awkward to implement on the J-machine, these issues have been resolved in designs currently under construction at MIT.  ...
