How to install KVM on Ubuntu

Kernel-based Virtual Machine, known as KVM, is an open-source virtualization tech built into the Linux kernel. This virtualization module in the Linux kernel allows the kernel to work as a hypervisor. This software can run multiple Linux or Windows guest virtual machines. Each guest OS is isolated from the others and has its operating system and dedicated virtual hardware like network interfaces, CPUs, storage, and memory.
