cpu虚拟化开启有必要吗(amd开启虚拟化)

The greatest practicality of virtualization technology is to install a virtual machine in the system.

For example, now is the era of Win7 or higher systems, but you still want to use some programs under XP, then you don’t need to install another XP at all, just install Microsoft’s own XP virtual machine Just machine. You can virtualize an XP in the current system and use it just like a real computer. You need to turn it on, install the driver, insert the USB flash drive... everything is done with the mouse, which is an operation in virtual reality. This is the most direct use of virtualization.

If your CPU does not support virtualization technology, then you cannot use Microsoft's official virtual machine.

In the BIOS, find Virtualization, go in and turn on the virtualization option.

Note that some old CPUs, such as lower versions of Pentium dual-core, do not support it, so they cannot be opened

Extended information:

< p>In computers, virtualization (English: Virtualization) is a resource management technology that abstracts and transforms various physical resources of the computer, such as servers, networks, memory, and storage, to break the physical structure. The inseparable barriers between them allow users to apply these resources in a better way than the original configuration. These new virtual portions of resources are not limited by how existing resources are deployed, geographically or physically configured. Generally referred to as virtualization resources include computing power and data storage.

In actual production environments, virtualization technology is mainly used to solve the problem of overcapacity of high-performance physical hardware and the reorganization and reuse of old hardware with low capacity, and to make the underlying physical hardware transparent, thereby maximizing of utilizing physical hardware.

Compared with traditional central processing units, microprocessors have the advantages of small size, light weight and easy modularization. The basic components of a microprocessor are: register file, arithmetic unit, timing control circuit, and data and address bus.

Since humans invented the transistor in 1947, semiconductor technology has experienced several generations such as silicon transistors, integrated circuits, very large scale integrated circuits, and very large scale integrated circuits in more than 50 years. The development speed is as fast as What other industries don’t have. Semiconductor technology has had a wide-ranging impact on the entire society, so it is called the "seed of the industry."

The central processing unit refers to the component inside the computer that processes data and controls the processing process. With the rapid development of large-scale integrated circuit technology, chip integration density is getting higher and higher, and the CPU can be integrated in This large-scale integrated circuit device with the function of a central processing unit on a semiconductor chip is collectively called a "microprocessor". It should be noted that the microprocessor itself is not the same as a microcomputer, but only the central processing unit of the microcomputer.

Microprocessors are everywhere. Whether they are home appliances such as video recorders, smart washing machines, and mobile phones, or car engine controls, CNC machine tools, missile precision guidance, etc., various microprocessors must be embedded in them. device. Microprocessors are not only the core components of microcomputers, but also key components of various digital smart devices. International high-end computing systems such as ultra-high-speed supercomputers and mainframe computers are also built using a large number of general-purpose high-performance microprocessors

Yes. If you need to use a virtual machine or Jingjing Software CPU virtualization software, you need to enable CPU virtualization. CPU virtualization is IntelVT or AMD-V technology, which can provide hardware-level support to make virtualization software such as virtual machines or Docker containers more efficient. Operate stably, more efficiently and more safely. Kanjing Software Technology (Beijing) Co., Ltd. was established in 2018 and is located in Beijing. It is an enterprise mainly engaged in technology promotion and application services, with a registered capital of 2 million yuan.

CPU virtualization is a technology that allows multiple virtual machines (VMs) to be run on a single physical central processing unit (CPU), each Virtual machines are regarded as independent operating systems and computing environments. The main uses of CPU virtualization include the following.

1. Improved resource utilization: Through CPU virtualization, multiple virtual machines can be run on one physical server. All machines can run operating systems and applications independently. This can make fuller use of the computing resources of the physical server, improve server utilization, and reduce hardware investment costs.

2. Isolation and security: Virtual machines are isolated from each other, and each virtual machine runs in its own virtual environment. This provides greater security and prevents a failure or attack on one virtual machine from affecting other virtual machines and physical servers. Virtual machines can run different operating systems independently, allowing different applications to run in an isolated environment, reducing mutual interference and conflicts.

3. Flexibility and scalability: Through CPU virtualization, virtual machines can be easily added, deleted, or reconfigured as needed. This flexibility makes it easier and more efficient to deploy and manage multiple applications on the same physical server. In addition, the computing resources of virtual machines can be dynamically allocated and adjusted as needed to meet the needs of different workloads.

4. Rapid deployment and backup: With CPU virtualization, new virtual machine instances can be quickly deployed without purchasing and setting up new physical servers. In addition, due to the independence of virtual machines, virtual machines can be easily backed up, migrated and restored to ensure data security and availability.

CPU virtualization provides enterprises and individuals with higher resource utilization, flexibility, scalability and security. It is one of the important technologies widely used in the field of modern computing, supporting the development of application scenarios such as cloud computing, virtualized environments, server sharing and containerization.
