A brief introduction to KVM of VPS virtualization architecture

When sharing information about vps discounts, I always mention what kind of virtual architecture to use. Today, this site has compiled an introduction to KVM, the vps virtualization architecture. Anyway, that’s it. There is no need to investigate in depth.

Introduction to KVM on VPS technology

KVM (full name is Kernel-based Virtual Machine) is a full-featured virtualization solution on the x86 hardware platform under Linux. It includes a loadable kernel module kvm.ko that provides and virtualizes the core architecture and processor specification modules.

KVM technology has evolved from its original concept into an enterprise IT infrastructure management system. Servers and devices located in multiple remote locations can be directly accessed from a single interface such as kvm client management software.

Use KVM to reference the kernel virtual machine and kvm to reference the hypervisor (used to start a new virtual machine).

Virtualization can also use more complex formats, where a single computer appears to have multiple architectures (to one user, it is a standard x86 platform; to another, it is an IBM Power PC® platform).

This form of virtualization is often called hardware emulation.

KVM over IP solutions now include complete multi-site failover capabilities, a direct interface compliant with the new server management standard (IPMI), and the ability to map local storage media to remote locations.

Using KVM allows multiple virtual machines including Linux and Windows to have private hardware, including network cards, disks, graphics adapters, etc.

Finally, a simpler type of virtualization is operating system virtualization, in which a single computer can run multiple operating systems of the same type. This kind of virtualization can isolate multiple servers with a single operating system (which means they must all use the same type and version of the operating system).
