KVM Full Name (kernel-based virtual machine) is an open source system virtualization module that is integrated into the 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

For KVM and NFS storage, the graphic interface mode and command line mode are used. First, we will introduce the command line method.

To save costs, the company needs to migrate some of its services to the virtualization platform. Today, we have installed the virtual machine and take notes. 1. system installation on the Physical Machine (Hard Disk: 300 GB + 300 GB ): Centos6.5 64-bit.
