 如何在Linux中用命令行工具管理KVM虚拟环境
 ================================================================================
-在我们[KVM系列专题][1]的第四部分，我们将会一起讨论下命令行界面下来管理KVM环境。We use ‘virt-install’ CL tool to create and configure virtual machines, virsh CL tool to create and configure storage pools and qemu-img CL tool to create and manage disk images.
