Noun analysis: What is Microsoft's server Hyper-V technology

Hyper-V, the next generation of hypervisor-based server virtualization technology in Windows Server 2008, can help address many virtualization business challenges. It is now possible to create virtual machines that can leverage the available hardware, run multiple operating systems, and manage virtual and physical resources using the same industry standard tools.

Hyper-V's main features include:

New, improved architecture: The new 64-bit micro-core hypervisor architecture enables Hyper-V to offer a wide range of device support and improvements. Performance and security.

A wide range of OS support: Extensive support for running different types of operating systems simultaneously, including 32-bit and 64-bit systems across different server platforms, such as Windows, Linux, and other systems.

SMP Support: Ability to support up to 4 multiprocessors (SMPs) in a virtual machine environment, enabling you to take advantage of multi-threaded applications in virtual machines.

Memory Support: Supports a large memory allocation per virtual machine, allowing you to virtualize the most workload, making Hyper-V an ideal platform for large enterprises and small and medium enterprises.

Improved storage access: Bypassing through disk access and extensive support for SAN and internal disk access, Hyper-V provides greater flexibility to optimally configure and utilize storage environments .

Network Load Balancing: Hyper-V includes new virtual switching capabilities. This means that virtual machines can be easily configured to work with Windows NLB to balance the load across virtual machines on different servers.

New Hardware Sharing Architecture: With the new Virtual Service Provider/Virtual Service Client (VSP/VSC) architecture, Hyper-V improves on core resources such as disk, network, video, etc. Access and use.

Quick Migration: Hyper-V leverages the high-availability features familiar with Windows Server and System Center management tools to quickly move a running virtual machine from one physical host system to another with minimal downtime.

Virtual Machine Snapshot: Hyper-V provides the ability to take snapshots of running virtual machines so that it is easy to return to the previous state and improve the overall backup and recoverability solution.

Scalability: With multi-processor and multi-core support at host level and improved memory access within virtual machines, you can now scale your virtual environment vertically to support a given host. A large number of virtual machines continue to scale with multiple hosts with fast migration.

Extensibility: Hyper-V's standards-based WMI interface and APIs enable independent software vendors and developers to quickly build custom tools, utilities, and enhancements for virtualization platforms.

The virtual host provided by Apport is based on Windows Server 2008 Hyper-V, which is the best in terms of security and performance. In a sense, it is a cross-era virtualization technology; with the help of the hypervisor management layer, the physical hardware performance is fully utilized in the virtualized environment. After a year of testing, we found that the performance, stability and security of the Hyper-V virtual machine based on the native 64-bit Hypervisor architecture is completely unmatched by the Virtuzzo VPS. In the Hyper-V virtual machine you can fully enjoy the full processing power of the physical server Xeon CPU, we do not make any resource restrictions. Virtuzzo's products are by default limited to all generated virtualized environments. The default is 1000 CPU Units, and the process is also limited. The default is 100 Processes. In addition, the memory occupied by the virtual machine running Hyper-V must be physical memory, and Virtuzzo can use virtual memory as the memory of the user virtualization environment! As for who is right and who is wrong, please also ask the user to decide.

It can be said that the Hyper-v virtual machine is the virtualization host with the closest performance to the physical host. It can completely replace the physical host and be used as the actual production environment. We believe that applications based on multi-core virtualization technology can double your business efficiency!

The virtual machine architecture can be divided into two categories:

The first type is called the host architecture, which means that the virtualization management layer runs on the host operating system and depends on the host. The operating system to emulate a hardware device to run a virtual machine on it has the advantage of requiring low physical hardware but relatively poor performance. Common examples are Microsoft's Virtual PC/Virtual Server; VMware's VMware Workstation/VMware Server.

The second type is called bare metal architecture, which runs the virtualization management layer directly on the hardware. The advantage is that the performance is better. Virtualized management layer of bare metal architecture, generally called Hypervisor, or VMM (Virtual Machine Monitor)

VMware ESX Server is relatively fat because it integrates the underlying physical hardware drivers into the hypervisor management layer. . Obviously, the performance of this architecture is better, but the requirements for the underlying physical hardware are relatively high, and the compatibility and security challenges are relatively high.

Microsoft's Hyper-V, Hypervisor management layer is only used to manage the CPU and memory, and does not include the underlying physical hardware drivers, so the management looks thin. Since it does not include hardware drivers, the amount of code is small, security is higher, and compatibility is better, but the efficiency is not as good as that of fat management.
