libguestfs is a C library and a set of tools for accessing and modifying virtual disk images used in platform virtualization.The tools can be used for viewing and editing virtual machines (VMs) managed by libvirt and files inside VMs, scripting changes to VMs, creating VMs, and much else besides.

Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. [ 1 ]
libvirt is an open-source API, daemon and management tool for managing platform virtualization. [3] It can be used to manage KVM , Xen , VMware ESXi , QEMU and other virtualization technologies. These APIs are widely used in the orchestration layer of hypervisors in the development of a cloud-based solution.
use KVM, Xen or QEMU virtual machines, running either locally or remotely. use LXC containers; Support for FreeBSD's bhyve hypervisor has been included since 2014, though it remains disabled by default. [4]
[citation needed] QEMU can also use KVM on other architectures like ARM and MIPS. [14] Intel's Hardware Accelerated Execution Manager (HAXM) is an open-source alternative [15] to KVM for x86-based hardware-assisted virtualization on NetBSD, Linux, Windows and macOS using Intel VT.
oVirt is a free, open-source virtualization management platform. It was founded by Red Hat as a community project on which Red Hat Virtualization is based. It allows centralized management of virtual machines, compute, storage and networking resources, from an easy-to-use web-based front-end with platform independent access.
Red Hat Virtualization (RHV) formerly known as Red Hat Enterprise Virtualization, is an x86 virtualization product developed by Red Hat, [2] and is based on the KVM hypervisor. [3] Red Hat Virtualization uses the SPICE protocol and VDSM (Virtual Desktop Server Manager) with a RHEL -based centralized management server.
The K virtual machine (KVM) is a virtual machine developed by Sun Microsystems (now owned by Oracle Corporation), derived from the Java virtual machine (JVM) specification. The KVM was written from scratch in the programming language C. It is designed for small devices with 128K to 256K of available computer memory, and minimizes memory use. It ...
