Title: The Innovations of Yaohui Hu

Introduction

Yaohui Hu is a notable inventor based in Binghamton, NY (US). He has made significant contributions to the field of virtualization technology, holding a total of 4 patents. His work focuses on enhancing the capabilities of hypervisors and virtual machines, which are crucial in modern computing environments.

Latest Patents

One of Yaohui Hu's latest patents is centered around Multi-hypervisor virtual machines. This innovation allows a hypervisor to run other hypervisors as guests, enabling a level-0 (L0) hypervisor to operate multiple level-1 (L1) hypervisors. Each L1 hypervisor can further run multiple level-2 (L2) virtual machines (VMs), with each L2 VM restricted to a single L1 hypervisor. The Span technology he developed provides a Multi-hypervisor VM where a single VM can run on multiple hypervisors simultaneously. This allows the VM to leverage different services from various hypervisors co-existing on a single physical machine. Span facilitates the sharing of the memory footprint of the VM across two hypervisors and distributes the responsibilities for CPU and I/O scheduling between them. As a result, Span VMs can achieve performance levels comparable to traditional single-hypervisor nested VMs for common benchmarks.
