Virtualization technology has matured significantly today, thanks to the active participation of major internet companies. It relies on the Hypervisor to map virtual resources (such as vCPU, virtual memory, virtual devices, etc.) to the physical resources of the Host, thereby providing multiple virtual machine resources and maximizing hardware resource utilization. For instance, the VxLAN technology … Read more

Virtualization can be thought of as “building a house”: Type I (Bare Metal) directly builds a “virtualization layer” (Hypervisor) on the “foundation”—the bare metal hardware, and then treats each operating system as a “tenant”. There is no “landlord”; the house is directly on the foundation, providing the best performance. Typical representatives include: VMware ESXi, Xen, … Read more
During a technical exchange, a client raised a rather common viewpoint: “Our hypervisors are deployed on an isolated management internal network, separate from the business network, and are completely inaccessible from the outside, so they are very secure and will not be attacked.” Placing core infrastructure in an isolated network is indeed the first step … Read more
Today, I want to discuss an “old” topic—server virtualization, which is my area of expertise. It is considered old because the core idea of this technology was born over half a century ago. However, it is also new because even today, it remains the cornerstone of our entire digital world. The apps on your phone, … Read more
Produced by | Fuxin Microelectronics Overview of Virtualization 1.1 Motivation and Benefits Virtualization is a widely used technology that underpins almost all modern cloud computing and enterprise infrastructure. Developers can run multiple operating systems on a single machine based on virtualization capabilities, allowing software testing without the risk of damaging the main computing environment. Virtualization … Read more

In today’s digital age, virtualization technology has become an important force driving the development of the computer field. Imagine a physical host running multiple isolated virtual machines simultaneously, each appearing to have its own independent hardware resources. How is all this achieved? Today, let us embark on this mysterious exploration of Linux IO virtualization, where … Read more
Good afternoon, everyone. This article is quite long because Linux kernel virtualization is indeed a challenging concept that took me a lot of time to research. The main purpose of learning this knowledge point is still related to my DPU PhD project. While reading literature today, I came across a conference paper on “DPU Virtualization … Read more
