Abstract

Virtualization has become widespread across all computing environments, from edge devices to cloud systems. Its main advantages are resource management through abstraction and improved isolation of platform resources and processes. However, there are still some important tradeoffs as it requires significant support from the existing hardware infrastructure and negatively impacts performance. Additionally, the current approaches to resource virtualization are inflexible, using a model that doesn't allow for dynamic adjustments during operation. This research introduces Light Virtualization (LightV), a new virtualization method for commercial platforms. LightV uses programmable hardware to direct cache coherence traffic, enabling precise and seamless control over which resources are virtualized. The paper explains the core principles of LightV, explores its capabilities, and shares initial findings from a basic proof-of-concept module tested on commercial hardware.
