The architecture of virtual machines
@article{Smith2005TheAO, title={The architecture of virtual machines}, author={James E. Smith and Ravi Nair}, journal={Computer}, year={2005}, volume={38}, pages={32-38} }
A virtual machine can support individual processes or a complete system depending on the abstraction level where virtualization occurs. Some VMs support flexible hardware usage and software isolation, while others translate from one instruction set to another. Virtualizing a system or component -such as a processor, memory, or an I/O device - at a given abstraction level maps its interface and visible resources onto the interface and resources of an underlying, possibly different, real system…

Adaptive virtual machine scheduling and migration for embedded real-time systems
- Computer Science
- 2015
The first contribution is an algorithm for the partitioning of virtual machines to homogeneous cores, which produces mappings that support adaptive scheduling and the protection of safety-critical systems and a virtual machine scheduling architecture that combines real-time guarantees with an adaptive management of the computing power.
