CentOS 6.5 Installation of KVM virtualization

First, KVM IntroductionKVM (kernel-basedvirtual machine), a kernel-based VM, is a virtualized infrastructure used in the Linux kernel to transform the Linux kernel into a hypervisor. KVM was introduced into the Linux 2.6.20 core in February 2007 and ported to FreeBSD and Illumos in a way that can load core modules.KVM runs on an x86 platform with Intel VT or AMD-V capabilities. It is also ported to the S/390,POWERPC and IA-64 platforms. In Linux kerne

Discussion on the technology of virtualization

virtualization technologyVirtualization technology is divided into the following major categories: Platform Virtualization (Platform virtualization) for virtualization of computers and operating systems. Resource Virtualization (Resource virtualization), for specific system resource virtualization, such as memory, storage, network resources and so on. Application Virtualization (Application Virtualization), including simulation, simulation, interpretation technology, and more.

Features of cloud desktop and desktop virtualization

Cloud Desktop as desktop virtualization refers to virtualizing the desktop of a computer to achieve the security and flexibility of desktop use. Access to our personal desktop systems on the Web can be accessed from any device, at any location, at any time.Server virtualization and Desktop virtualization use a software kernel called the hypervisor to run multiple operating systems on the same physical server hardware. Each operating system is independ

How Nova is counting OpenStack compute resources

IntroductionOPS colleagues often encounter these four questions: How does Nova count OpenStack computing resources? Why FREE_RAM_MB, FREE_DISK_GB will be negative? Even if FREE_RAM_MB, FREE_DISK_GB is negative, why is the virtual machine still able to create success? The use of random scheduling due to insufficient resources will cause the virtual machine to fail, while the specified host can be created successfully? This article will start with the above four questions

What is the difference between hyper-V and virtual_pc?

There are many differences. The comparison between Virtual PC and vitual server and virtual server and hyper-V is more comparable. 1. vitrual PC can only Virtualize a 32-bit system. Even if a 64-bit vitual PC runs, it can only Virtualize a 32-bit system, microsoft will no longer launch a virtual PC version capable of virtualizing a 64-bit System2 Virtual PC hardware is virtual, and hyper-V runs directly on the physical server hardware on the hypervisor
