Installation of KVM (Hypervisor for Virtualization)

Installation of  KVM


Mandatory prerequisite:


            1. Linux 64 bit Operating System (The commands mentioend are for Ubuntu Linux Operating System latest version).

Installing KVM (Hypervisor for Virtualization)


1. Please check if the Virtualization flag is enabled in BIOS
                        Run the command in terminal
                                    egrep -c 'vmx|svm)' /proc/cpuinfo

                        If the result is any value higher than 0, then virtualization is enabled.
                        If the value is 0, then in BIOS enable Virtualization – Consult system administrator
                        for this step.

2. To check if your OS is 64 bit,
                        Run the command in terminal

                        uname -m

                        If the result is x86_64, it means that your Operating system is 64 bit Operating system.

3. Few KVM packages are availabe with Linux installation.
                        To check this, run the command,
           
                        ls /lib/modules/{press tab}/kernel/arch/x86/kvm    
                       
                        The three files which are installed in your system will be displayed
                        kvm-amd.ko      kvm-intel.ko           kvm.ko

4. Install the KVM packages
           
             1. Switch to root (Administrator) user
           
                        sudo -i

              2. To install the packages, run the following commands,
             
                        apt-get update
                        apt-get install qemu-kvm
                        apt-get install libvirt-bin
                        apt-get install bridge-utils
                        apt-get install virt-manager
                        apt-get install qemu-system

5. To verify your installation, run the command
                        virsh -c qemu:///system list
it shows output

                        Id                Name                  State
                        -------------------------------------------

If Vms are running, then it shows name of VM. If VM is not runnign, the system shows blank output, whcih means your KVM installation is perfect.

6. Run the command
                        virsh –connect qemu:///system list –all

7. Working with KVM

                        run the command
                        virsh
                        version  (this command displays version of software tools installed)
                        nodeinfo (this command displays your system information)
                        quit (come out of the system)
                       
8. To test KVM installation - we can create Virtual machines but these machines are to be done in manual mode.
