Linux has both good flexibility and excellent virtualization. But recently, with the emergence of kernel Virtual Machine KVM), the prospect of Linux Virtualization has changed. KVM is the first virtualization solution that forms part of mainstream Linux kernel V2.6.20. KVM supports Virtualization of Linux customers' operating systems-or even Virtualization of the

virtual machine directly to the physical hardware, thereby improving the performance of the operating system running in the virtual machine. Such as:KVM is a typical representation of this acceleration pattern. In the community, KVM and Xen are often compared, but they are totally different. As can be seen, the use of kernel modules to accelerate this mode, the main operating system is still dominant, the kernel module just open a hole in the main op

To be exact, a KVM is a module of Linux. You can use Modprobe to load the KVM module. After you load the module, you can further create a virtual machine from another tool. However, only the KVM module is not enough, because the user can not directly control the kernel module to do things: there must be a user space tool to do. This user-space tool, the developer

It is managed using Linux's own scheduler, so its core source code is few compared to Xen. KVM Virtualization requires hardware support (such as Intel VT Technology or AMD V technology) and is hardware-based full virtualization. The early days of Xen were software-based

Installation and use of KVM virtualization technology under LinuxThe advent of the cloud era, the widespread use of virtualization. Let's redefine the technology . And today's well-known virtualization products are VMware vsphere, HYPER-V,XEN,KVM. VMware is a marketplace for virtualization, and Hyper-V is virtualization under the Windows platform, and Xen is a semi-virtualized product.

Introduced:KVM (kernel-based virtual machine, or kernel-level VM) is an open-source system virtualization module that is used for virtualization infrastructure in the Linux core, and KVM was introduced into the Linux 2.6.20 core in February 2007 and is Introduction of FreeBSD. It is managed using Linux's own scheduler, so its core source code is few compared to Xen. KVM has become one of the mainstream VMM

Kvm Basic Principle 2The idea of KVM is to add a virtual machine management module on the basis of Linux, and reuse the completed process scheduling, memory management, IO management, and other parts in the Linux kernel, therefore, KVM is not a complete simulator, but a kernel plug-in that provides virtualization functions. The specific simulator work is complete

Getting started with Linux: KVM for Virtual Machine experience In the previous article, I demonstrated the use, effect and performance of the Virtual Machine Software QEMU, and analyzed the different virtual machine pursuits of different users. However, whether it is a desktop or enterprise-level user, the pursuit of Virtual Machine Software is a bit common, that is, performance. QEMU is a powerful Virtual Machine software. It can simulate all the har
