Kernel-based Virtual Machine (KVM) is an open-source virtualization technology

 Kernel-based Virtual Machine (KVM) is an open-source virtualization technology.

 Kernel-based Virtual Machine (KVM) is an open-source virtualization technology that allows system administrators to create and manage virtual machines (VMs) on Linux systems. It is a type of hypervisor, a software layer that enables multiple operating systems to run on the same computer hardware at the same time.

KVM provides a complete virtualization solution for Linux, allowing users to take advantage of the same hardware resources across multiple operating systems. KVM is included in most Linux distributions, making it easily available to anyone running Linux.

How to install and configure Kernel-based Virtual Machine (KVM)

1. Install KVM Before you can install KVM, you need to make sure that your system supports hardware virtualization. To check if this is the case, execute the following command: egrep -c '(vmx|svm)' /proc/cpuinfo If the output is greater than 0, then your processor supports hardware virtualization. Now you can install KVM by running the following command: sudo apt-get install qemu-kvm libvirt-bin virtinst bridge-utils 2. Configure Networking KVM uses a virtual network to connect virtual machines to the outside world. To configure it, you will need to edit the /etc/network/interfaces file and add the following lines: # KVM Bridge auto br0 iface br0 inet static address 192.168.1.10 netmask 255.255.255.0 gateway 192.168.1.1 bridge_ports eth0 bridge_stp off bridge_fd 0 Save the file and restart the networking service by running the following command: sudo /etc/init.d/networking restart 3. Start the KVM Daemon To start the KVM daemon, run the following command: sudo /etc/init.d/libvirt-bin start 4. Create a Virtual Machine To create a virtual machine, use the virt-install command. This command will walk you through the process of creating a virtual machine. For example, to create a virtual machine with 512MB RAM and 10GB of disk space, run the following command: sudo virt-install --name myVM --ram 512 --disk path=/var/lib/libvirt/images/myVM.img,size=10 5. Connect to Virtual Machine Once the virtual machine has been created, you can connect to it using the virt-viewer command. To connect to the virtual machine, run the following command: virt-viewer myVM This will open a window that you can use to interact with the virtual machine.
