Learn how to install KVM
Learn how to install KVM (Kernel-based Virtual Machine) on Debian12 and configure the bridge network. The installation process demonstrated in this tutorial is applicable to Ubuntu and other Debian-based Linux systems as well.
KVM is a powerful virtualization solution that enables you to run multiple virtual machines on a single physical machine. Follow the step-by-step installation guide provided in this video to set up KVM on your Debian system.
Download Ubuntu Server :- https://ubuntu.com/download/server
Here's what you'll learn in this tutorial:
Update your system: Start by updating your system to ensure that you have the latest packages and dependencies. Execute the command "sudo apt update -y" in the terminal.
Install KVM packages: Install the necessary KVM packages by running the following command in the terminal:
"sudo apt install qemu-kvm libvirt-clients libvirt-daemon-system virtinst bridge-utils -y"
This command will install QEMU, libvirt, bridge-utils, and virtinst, which are essential components for KVM.
Add user to libvirt group: To allow the current user to access and manage virtual machines, add the user to the libvirt group using the command "sudo adduser $(whoami) libvirt".
Enable and start the libvirt service: Enable and start the libvirt service, responsible for managing virtualization on your system, by executing the following commands:
"sudo systemctl start libvirtd"
"sudo systemctl enable libvirtd"
Check the status of kvm using the command "lsmod | grep kvm" to ensure it is installed and loaded properly.
Configure networking: Configure the networking settings for KVM. Start by listing all network configurations defined in libvirt using the command "sudo virsh net-list --all". Activate the default network configuration with the command "sudo virsh net-start default", and enable autostart using "sudo virsh net-autostart default".
Load vhost_net module: Instruct the system to load the vhost_net module into the kernel if available, using the command "sudo modprobe vhost_net". This module ensures proper networking functionality when using virtio network devices in KVM.
Configure networking kernel modules at boot time: Open the file "/etc/modules" and add "vhost_net" to ensure the module is loaded at boot time.
Create a bridge network: Set up a bridge network so that virtual machines can receive IP addresses within the same range as the host machine. Create a backup of the "/etc/network/interfaces" file and add the bridge network configurations. Customize the address, broadcast, netmask, gateway, and bridge_ports values according to your local network setup.
Restart the network: Restart the network by running the command "sudo systemctl reload network" or "sudo systemctl reload networking.service" to apply the changes made to the bridge interface. Verify the additional network interfaces using the command "ip a".
