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
KVM supports multiple storage options, including virtual disk files, file system-based storage, and device-based storage.
Virtual Disk File
To implement kernel-based Virtual Machine (KVM) storage management, you can use LVM (logical volume manager) and create a storage pool. When the system creates a KVM virtual machine, the virtual disk file is used as the backe
ObjectiveThe purpose of this article is to solve the problem of poor performance of Windows virtual machines when using Cloudstack (Cloudplatform), based on the KVM virtualization platform.This performance, mainly refers to disk IO and network card performance.Related documentsSince the CS document only emphasizes the concept of PV, different hardware interface types are distinguished according to PV mode. So we collect some links for literacy.About P
NAT method by default to communicate with the Virtual Machine Nic, in the actual production environment, in most cases, we use the Bridge method for communication between physical machines and virtual machines. The method for deleting this virbr0 has been described in the above link, this article mainly describes the simple implementation principle of Bridge and the actual configuration method.

In September 29, inspur group recently signed a strategic cooperation agreement with red hat, an open-source manufacturer. Based on the new-generation Red Hat Enterprise Operating System (Red Hat Enterprise Linux7 ), as well as comprehensive strategic cooperation between the nine categories of x86 platform products of inspur. According to the Cooperation Agreement, inspur will become a Red Hat OEM Partner. It is reported that the OEM Partner is the highest-level partner of

Linux is short for GNU/Linux. It is usually the general name of various Linux releases. Common Linux Manufacturers include RedHat/Novell.
RedHat has two major Linux product series, one of which is the free Fedora Core series. It is mainly used for desktop versions and provides support for many new features. Another product series is the paid enterprise series, which is divided into as, es, WS, and other

QEMU has a deep relationship with KVM and can even assume that both sides are inherently software, and that QEMU is the control part of the application layer, and KVM is the kernel execution part. Software reuse can be so seamless to the point, is a very magical thing, also shows the KVM design

Adding KVM to the Linux kernel is an important milestone in the development of Linux, which is also the first virtualization technology integrated into the Linux main kernel. In the KVM model, each virtual machine is a standard process managed by the Linux scheduler. You can start the clie

This article adds some own understanding on the basis of translation.QEMU, Virtual box, VMware, Xen are VMS, the average user is exposed to more virtual box and VMware, are used in Ubuntu running Windows, or Windows running Ubuntu.QEMU is actually the most popular open source simulator, which can simulate x86, ARM, MIPS, and so on, and can use hardware acceleration, such as the HAXM under the Linux KVM
Introduction to KVM:KVM, an open source system virtualization module, is integrated into the major distributions of Linux since Linux 2.6.20. It uses the Linux own scheduler import row management, therefore relative to Xen, its core source code is very few. KVM has become one of the mainstream VMM in academia today. KVM Virtualization requires hardware support (such as Intel VT Technology Ring AMD v technol
