Creating Virtual Machines on Ubuntu through KVM

摘要

KVM (Kernel-based Virtual Machine) is a virtualization infrastructure for the Linux kernel which turns it into a hypervisor KVM only works if your CPU has hardware virtualization support - either Intel VT-x or AMD-V. Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc. Step1: First you have to determine whether your system supports virtualization or not. Run the command given below and check if you get a value 0. This wil indicate that your CPU doesn't support hardware virtualization, while a score of 1 or more indicates that it does. You may still have to enable hardware virtualization support in your computer's BIOS, even if this command returns a 1 or more.
