1. Preface
Currently, we are engaged in cloud computing IAAs. virtualization is an important part of IAAs. Therefore, during this period, we have studied Virtual Machine technologies and tools. The purpose of this research is not only to use this tool, however, by studying and understanding the implementation mechanism and principles of technology, we need to know exactly what it means. This article is the beginning of my entry into this technology field. While recording my own progress, hope to
1, first download KVM source code: http://www.linux-kvm.org/page/Downloads or http://sourceforge.net/projects/kvm/files/ to select the latest version

After searching for a long time on the Internet, I found that if vmware-workstation does not support the fence function (Version 9 has never been used and is not supported by version 8 ). Unless it is an ESX or vmware-server product, I personally think it is possible that the virtualization layer must beEssenceIt is an operati

Hello everyone, the theme of this Sholi sharing is kvmlibvirt basic concepts and development of the talk, the content of some messy loose, mainly based on their early collation of notes and practical sentiment, some content is inevitably biased, hope forgive me. First of all, we need to understand the basic knowledge, most of the content in the Sholi works have more detailed explanations, can read the reference.

KVM (for kernel-based virtual machine) is a complete hardware virtualization solution for Linux based on the X86 architecture. It can run directly without modifying the Linux operating system and the Windows operating system. KVM is open source software and integrates the kernel after the Linux kernel 2.6.20.

I. KVM Introduction
KVM is an open-source software. It is short for kernel-based virtual machine (kernel-based virtual machine). It is an open-source system virtualization module that is fully virtualized based on hardware, however, hardware support is required (such as Intel VT or amd v ). Linux 2.6.20 and later are in

Developers can take full advantage of the Linux kernel has been implemented by the mature features, on the basis of the design, implementation of their own kernel modules, in order to expand the functionality of the kernel to meet their own requirements. KVM, for example, exists as a kernel module, adding virtualization functionality to the Linux kernel.
