How to install KVM on Ubuntu 14.04 LTS Headless Server

To install KVM on an Ubuntu 14.04 LTS headless server, follow these steps:

1. Install the required packages:

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

1. Add your user to the kvm group:

sudo adduser <username> kvm

Replace <username> with your actual username.

1. Verify that KVM is installed and functioning properly:

sudo virsh list --all

This command should display a list of virtual machines, which should be empty if you have not created any virtual machines yet.

1. Configure the network for KVM virtual machines:

rnBy default, KVM virtual machines will use a network bridge device to connect to the host machine's network. To configure the network bridge, you can follow these steps:

• Create a new bridge interface:

sudo nano /etc/network/interfaces

Add the following lines to the file:

auto br0
iface br0 inet dhcprn bridge_ports eth0
 bridge_stp off
 bridge_fd 0
 bridge_maxwait 0

Replace eth0 with the name of your host machine's network interface.

• Restart the network service:

sudo /etc/init.d/networking restart

After these steps, KVM should be installed and configured on your Ubuntu 14.04 LTS headless server. You can now create and manage virtual machines using the virsh command-line tool or other virtualization management tools.
