Performance – One of the main drawbacks of traditional virtualisation technologies is performance degradation compared to physical machines.But KVM brings more benefits compared to other virtualisation technologies. Since KVM is part of Linux, it installs natively, enabling straightforward user experience and smooth integration.

The main benefit of the KVM hypervisor is its native availability on Linux. KVM can only be used on a processor with hardware virtualisation extensions, such as Intel-VT or AMD-V. Every VM runs as a separate Linux process under systemd, with dedicated virtual hardware resources attached. It plugs directly into the kernel’s code and allows it to function as a hypervisor. KVM is available as a Linux kernel module. As a result, every VM completely simulates a physical machine. It provides each VM with all typical services of the physical system, including virtual BIOS (basic input/output system) and virtual hardware, such as processor, memory, storage, network cards, etc. KVM hypervisor enables full virtualisation capabilities.

In the following blog, we present the beginner’s guide to KVM on Ubuntu. But what are the benefits of KVM hypervisor and how do you get started? KVM comes with no licenses, type-1 hypervisor capabilities and a variety of performance extensions which makes it an ideal candidate for virtualisation and cloud infrastructure implementation. It installs natively on all Linux distributions and turns underlying physical servers into hypervisors so that they can host multiple, isolated virtual machines (VMs). KVM (Kernel-based Virtual Machine) is the leading open source virtualisation technology for Linux.
