KVM - Kernel Virtual Machine

For this project we are going to use KVM, to work with Windows and Linux guest operating systems. The host operating system during the whole project will be Linux 10.04 (64bits).

Installation of KVM

(following this documentation: https://help.ubuntu.com/community/KVM/Installation )

• First of all we should set the needed switches for the virtualization from bios.
• Once we set them we are going to see if our computer really supports KVM. If the output from this command is 1 or more, it does :

        egrep -c '(vmx|svm)' /proc/cpuinfo

  In our case,he output is 2, so we can continue with the installation.

• Now we are going to install the following packages:    
  • 'qemu-kvm' : the backend
  • 'libvirt-bin' : provides libvirtd which you need to administer qemu and kvm instances using libvirt
  • 'ubuntu-vm-builder' : powerful command line tool for building virtual machines
  • 'bridge utils' : provides a bridge from your network to the virtual machines

• We should test if the installation it's been successful with the following comand:

     If everything is correct we have to see this output:

     But during the installation the output was :

The problem was that the virtual conection (virbr0) created for the virtual machines, disable the eth0 conection. So I bring up the ethernet interface
with the following comand:
