KVM: (kernel-based virtual machine) kernel-based VMS KVM is hypervisor integrated into the Linux kernel, a full-virtualization solution for Linux with X86 architecture and hardware-enabled virtualization technology (Intel VT or AMD-V). It is a very small module of Linux, using Linux to do a lot of things, such as task scheduling, memory management and hardware device interaction and so on. In the form of pr

KVM is short for Kernel-based Virtual Machine. It is an open-source virtualization module. Today I will install KVM ON THE CentOS7 operating system. Below are my installation steps.

I. Structure and INTRODUCTION
KVM (kernel-based Virtual Machine) It was developed by Quramnet, the company was acquired by Red Hat in 2008;
Integrated into the kernel from the Linux 2.6.20, the kernel module makes Linux become a hypervisor layer;
It relies on the CPU virtualization instruction set, performance, security, compatibility, stability performance is good, each virtualization operating system performance as a single system process, and Li

Hello, everyone! Later KINAN article by me to write [ steal laughter ], leadership early arrangement down, a week an article hard task, but small series has been slow to hands, why? The article does not write well leader let me go away [ uppercase embarrassment plus grievance ] ... plan after weekly KINAN Public number for the general attention KINAN Reader friends to provide KVM basic knowledge of the popularization,KINAN the latest activity and so o
One, what is KVMKVM includes many parts: first, it is a Linux kernel module (now included in the mainline) used to convert the processor into a new user (Guset) mode. User mode has its own set of ring states, but the command of privileged RING0 is caught in the code of the manager (hypervisor). Since this is a new processor execution model, the code does not require any changes. In addition to processor state transitions, this kernel module also handles a small subset of low-level simulations,
KVM in 2013 years or so in the company at that time as a production environment in use, the habit, in their normal test environment also no longer use VMware Workstation and exsi. Recently, however, we are learning about the Rhel 7 version of the RHCE course. Get a set of RHCE environment after decompression found to be VMDK format. After conversion through the Qemu-img tool, the KVM is imported and the env

Do you know how to add system calling APIs in KVM? Here we will describe different systems calling APIs and their implementations for different j2s devices, I believe this article will surely help you gain some benefits.
How to add the system call API in KVM
We all know that KVM does not support Native function calls. If you want to add some system-called APIs, y

To use KVM, a graphical system must be installed in the system environment.
1. Check whether the machine supports virtualization.

Turn off the virtual machine and turn the virtual machine off by entering the shutdown command on the virtual machine;
Based on the Virt-manager to create the management virtual machine is complete, very simple.
We use the Cirros lightweight Linux system for the following experiments.
