Examined the decision to use KVM, because the machine configuration is not very high, the use of KVM performance will be better. The basic system chooses CentO

backgroundBecause the server in the production environment does not install the desktop environment, a graphical installation of simple operations is not suitable for batch deployment installations. Therefore, I prefer to install the KVM virtual machine under the command. In combination with some information and personal use, I have outlined some basic and commonly used methods.Installation ConfigurationI. Introduction to the environmentOperating syst

Introduction to Nesting Virtualization Nested virtualization (nested virtualization, recursive virtualization) is the process of running a hypervisor in a virtualized client, which is then virtualized to run a client. Nested virtualization includes not only the same hypervisor nesting (for example, KVM on KVM, Xen in Xen, VMware on VMware, and so on), but also the different hypervisor nesting (such as VMwa

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

Note: kvm must be configured on the basis of RedHat 6 later and requires at least 4 GB of memory. The cpu supports virtualization, 25 GB disk space, and 1 Gbps network interfaces.

To install a Linux operating system with virtualization functions (CentOS is used as an example here), we generally have two methods: 1. Install the virtualization package or configure the virtualization package on the PXE Server during the CD installation.2. Manually install virtualization components in a system without virtualization components installed If the environment we build must use virtualization, or virtualization is one of the main purposes of building this environment, we will inst

graphic interface. If it is a Windows virtual machine, we can now directly use the NIC and then give the NIC an IP address. For a Linux system, You Need To perform other operations to use the NIC. For more information, see Add a NIC under the command line below. Now we start to use the virsh attach-interface command to add the NIC. First, we use the virtual machine as the windows system as an example. Note that the virtual machine is running normally

Qemu-KVM is currently a popular virtualization technology. I will present a series of qemu-KVM content here in the next period. The virtualization mentioned here refers to the virtualization technology based on CPU hardware support. KVM (kernel-based Virtual Machine) Website: http://www.linux-kvm.org/page/Main_Page Introduction:

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
