Now coming back to the point of working of KVM, Linux is converted into a Type-1 hypervisor.
Before diving into that, one must be aware of the fact that even if there are multiple virtual machines running images, each of the virtual machines needs to have its own set of virtual private hardware, like network card, disk, graphics adapter, CPUs and many such more.Also, the loadable kernel module provides infrastructure for core virtualization. The selection between the processor-specific module is solely based on the type of processor hardware the machine is running on, either Intel or AMD. This virtualisation setup contains a loadable kernel module named kvm.ko and a module-specific to the processor kvm-intel.ko or kvm-amd.ko. KVM is an acronym for Kernel-based Virtual Machine. KVM is defined as an open-source solution for enabling full virtualization of Linux on x86 hardware (initially built for x86 but later ported to S/390, PowerPC, IA-64, and ARM as well) that constitutes of extensions for virtualization.
