KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware that allows running multiple unmodified virtual machines, each with its own virtualized hardware. The document outlines the server and client setup procedures for NFS and KVM, including installation commands and configuration files. It concludes by highlighting the benefits of KVM in reducing hardware costs and enhancing security in environments like cloud computing and educational labs.

2. WHAT IS KVM ?
1
KVM (for Kernel-based Virtual Machine) is a full virtualization
solution for Linux on x86 hardware containing virtualization
extensions (Intel VT or AMD-V). It consists of a loadable kernel
module, kvm.ko, that provides the core virtualization infrastructure
and a processor specific module, kvm-intel.ko or kvm-amd.ko.
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.
KVM is open source software. The kernel component of KVM is
included in mainline Linux. The userspace component of KVM is
included in mainline QEMU.

4. 1.INSTALL NFS SERVER
# apt-get install nfs-kernel-server
SERVER SETUP

5. 2.Create the exports/images file system and give permissions
# mkdir -p /exports/images
# chmod -R 777 /exports
# chmod -R 777 /exports/images
4

6. 3.Add the following two lines to /etc/exports
/exports *(rw,sync,no_root_squash,no_subtree_check)
/exports/images *(rw,sync,no_root_squash,no_subtree_check)
5

7. 4. Add the following line to /etc/hosts.allow
rpcbind mountd nfsd statd lockd rquotad : ALL
6

8. 5. Change the group and owner of /exports/images/ to ‘nogroup’.
# chown nobody:nogroup /exports/images/
7

9. To start, restart and stop commands for NFS server.
# service nfs-kernel-server start
# service nfs-kernel-server restart
# service nfs-kernel-server stop
8

10. 1. Install the required packages...
# apt-get install nfs-common
CLIENT SETUP
9

11. 10
2. Add the following line to /etc/hosts.allow.
rpcbind mountd nfsd statd lockd rquotad : ALL

12. 3. On the client we can mount the complete export tree with one command.
# mount server_ip_address:/exports/images /var/lib/libvirt/images
11

13. 4. Install KVM and supporting packages
# sudo apt-get install qemu-kvm libvirt-bin bridge-utils virt-manager
12

14. 5. Create User
# sudo adduser user_name
# sudo adduser user_name libvirtd
13

15. 6. Open Virtual Machine Manager Application
and Create Virtual Machine
# virt-manager
14

16. CONCLUSION
This System Software is very useful and easy to implement in
Batch Systems. This package is used to reduce Hardware cost
and also security issues. It is implemented in Cloud
Computing.
Colleges can implement it in Labs to reduce hardware cost as
Students use on less amount of resources during exams and
Labs.
