Virtualization in clouds

Shortened URL : goo.gl/r249Vg

1. What is virtualization ? There are 4 types
   • hardware virtualization : When VM is directly installed on a machine
   • operating system virtualization : When VM is directly installed on the host OS
   • server virtualization :
   • storage virtualization : Where physical storage is abstracted through another interface

Output :

Checking if the kernel supports the VM Architecture

Checking the CPU Info regarding system architecture

Installing KVM

sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils virt-viewer

• libvirt-bin provides libvirtd which you need to administer qemu and kvm instances using libvirt
• qemu-kvm (kvm in Karmic and earlier) is the backend
• ubuntu-vm-builder powerful command line tool for building virtual machines
• bridge-utils provides a bridge from your network to the virtual machines
