1, Virtual machine type: Type 1 hardware directly installed HPType 2 hardware on the install host above run VMM2. KVM OverviewKVM does not count type 1 and is not type two. Both features, he is a kernel module of Linux, the kernel itself does not have HV, when loaded with KVM, the kernel will become HV. At this point the hardware driver does not have to rely on others, the kernel itself can use these driver
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

Background: I recently worked on a virtual machine security project that uses KVM to support virtualization, involving code modifications for KVM and qemu. Because KVM can be loaded into the kernel as a module, You can compile the KVM module separately, instead of re-compiling the kernel each time (in view of the time

This article was sponsored by Xiuyi linfeng and first launched in the dark world.
In previous articles about NFS, we introduced NFS mounting and so on. This article describes how to use NFS as storage.
Since the topic of this article is about NFS, we should first build the NFS server. For detailed construction process, refer to "mud: using NFS storage with VSphere.

Objective
At work, we may have access to a KVM virtual machine, and many of the company's applications will run on a KVM virtual machine. Therefore, the skilled application of KVM is also one of the essential capabilities of operation dimension. So in the KVM practice, we are sure to think often about how to be more i
This article describes the basic installation of KVM.
No understanding or contact with KVM friends, in the beginning may be more confused, do not know how to learn, I will share under my learning process.

Concept:Kernel-based virtual Machine is an open source system virtualization module that has been integrated into various major distributions of Linux since Linux 2.6.20. 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 in academia today.KVM Virtualization requires hardware support (such as Intel VT Technology or AMD V technology). is hardware-based full virtualization.
Relationship between qemu and KVM
KVM is a virtual machine based on the Linux kernel ). In October 2006, a new Virtual Machine implementation solution was developed by qumranet in Israel. The Linux 2.6.20 kernel released in February 2007 contains KVM for the first time. Adding KVM to the Linux kernel is an important

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
