kvm虚拟化平台搭建(开虚拟机很伤电脑吗)

What is KVM and where is KVM generally used? What kind of people need it more? Commonly used
The so-called KVM is the abbreviation of Keyboard, Video and Mouse, and its official name is multi-computer switch. Simply put, it is a set of keyboard, monitor and mouse that can control 2, 4, 8, 16 or even more than 4096 computer hosts.
The value of KVM switches
KVM technology is developing at a rapid pace. From the birth of KVM 30 years ago to now, KVM has developed from a simple one to control many computer peripherals to capable of remote device management, power supply Management; can integrate an enterprise's globally distributed servers into a management platform without being restricted by the operating system; can use one IP address for management, and uses 128-bit SSL protocol encryption for all signals to ensure data security; the latest KVM technology has Multiple management terminals can manage tens of thousands of devices (servers and network devices) at the same time. For enterprises such as finance, securities, and insurance that have centralized large-scale data rooms and many branches, using the latest KVM solutions can greatly improve the management efficiency of enterprise IT equipment. Through the new generation of KVM solutions, IT engineers can flexibly manage and maintain the company's systems anytime and anywhere. KVM has been able to free enterprise IT administrators from simple and boring computer room maintenance and focus on more meaningful work. Specifically, whether the servers are centrally placed in the same data center computer room or scattered in several computer rooms in different locations, IT administrators can maintain and manage all devices anytime and anywhere, perform BIOS-level control and even start operations. /Power off the device. Regardless of whether these devices have an X86 architecture or a minicomputer, and whether the operating system is UNIX, LINUX, or WINDOWS, administrators can manage all devices on a unified operating interface. Some new KVMs can also provide multiple authentication functions, from UKEY to dynamic tokens, SMS, fingerprint recognition, etc., which can maximize system security. For all the equipment placed in the computer room, there is no need to equip it with a dedicated operating terminal to occupy valuable computer room space; it also avoids the need to hold a set of operating terminals (keyboard, mouse and monitor or notebook) as in the past. ) shuttles between noisy cabinets to complete maintenance work. If the administrator wants to operate a certain device, no matter where the administrator is, he only needs to use a computer connected to the Internet to set up, maintain and manage the device. Because this type of KVM solution uses an IP network to connect to the server, it completely removes the restriction of distance, and administrators can access and manage servers anywhere in the world. The benefits of this are obvious. The company does not have to spend a lot of travel expenses for administrators to fly from here to there to perform equipment maintenance or emergency treatment of problems that occur. In many cases, these problems can be solved by simply restarting the machine. The company also does not have to equip each branch with IT management personnel. Not only will there be a lot of salary expenses, but there will also be no inconvenience in personnel management. What's more important is that administrators can deal with unexpected problems in real time, no different from engineers on site, which greatly improves response speed and reduces unnecessary losses to the enterprise due to downtime.
KVM switch application scope:
Internet data center information control center telecommunications paging system securities/futures trading system bank data center industrial control environment teaching environment test center video surveillance power plant monitoring computer room management other multi-host environments· A set of keyboard, mouse, and monitor can support multiple hosts.

What are the virtualized cloud terminals based on kvmspice technology? Please give me an example

The KVM-based desktop virtualization solution uses the Spice protocol, such as Huake Cloud Terminal. The advantages of using virtualization in cloud terminals include saving space, improving efficiency, strengthening management, saving costs, remote management, environmental protection and energy saving. Among them, Huake Cloud recommends using X86 thin client hardware product models K520C K600Z K600A, etc.

What is server virtual KVM?
Hello, I am happy to answer your question.
KVM is the abbreviation of Kernel-basedVirtualMachine. It is an open source system virtualization module that has been integrated into all major Linux distributions since Linux2.6.20. It uses Linux's own scheduler for management, so compared to Xen, its core source code is very small. KVM has now become one of the mainstream VMMs in academia.
You can also understand it as installing a virtual machine (a computer) on your computer.
To put it simply, virtualization allows multiple virtual machines to be run on a physical server. The virtual machines share the CPU, memory, and IO hardware resources of the physical machine, but the virtual machines are logically isolated from each other. .
The physical machine is generally called the host, and the virtual machine on the host is called the guest.
