			<blockquote>
			A hypervisor (also known as a virtual machine monitor) is computer software that creates and runs virtual machines. The hypervisor performs the function of controlling the host processor and resources, determining their allocation to the guest operating systems. The hypervisor is a very practical way of getting things virtualized quickly and efficiently.

			There are two types of hypervisor. A Type 1 hypervisor is known as native or bare-metal. With this type, the hypervisor runs directly on the host’s hardware to control the hardware resources and to manage guest operating systems. In other words, the software hypervisor does not require an additional underlying operating system.

			The second type of hypervisor runs under a conventional operating system environment as a second layer, with the guest operating systems then running at the third level.

	KVM (for Kernel-based Virtual Machine) is a full, open source, virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.

			KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.

			Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc.

			KVM is open source software. The kernel component of KVM is included in mainline Linux, as of 2.6.20. The userspace component of KVM is included in mainline QEMU, as of 1.3.

oVirt – virtualization solution for your entire enterprise

by September 9, 2023 Steve Emms Documents

oVirt is a virtualization platform with an easy-to-use web interface. oVirt is built on libvirt which could allow it to manage virtual machines hosted on any supported backend, including KVM, Xen and VirtualBox. oVirt manages virtual machines, storage and virtualized networks.

oVirt Engine is the control center of the oVirt environment. It allows you to define hosts, configure data centers, add storage, define networks, create virtual machines, manage user permissions and use templates from one central location.

The project consists of the engine core (backend server), VDSM agents and a client side user interface (GWT based) and/or RESTful API to control the engine core.

oVirt has three web-based front-ends – for administrators, users and power users (for self provisioning). It also has a REST based API, a Python SDK and a CLI interface, which allows automation of most of its features.

oVirt is an open source software with backing from Red Hat and it is the base for Red Hat Enterprise Virtualization. oVirt is written in Java, over JBoss application server and GWT web framework for its user interface. VDSMd is written in Python.

Features include:

* High availability.
* Manage multiple virtual machines.
* Sophisticated web-based management interface for all aspects of your datacenter.
* Choice of means of allocation of VMs to hosts: manual, “optimised”, pinned.
* Live migration of VMs from one hypervisor to another.
* Add new hypervisor nodes easily and centrally.
* Monitor resource usage on VMs.
* Load balancing.
* Manage quotas for use of resources (storage, compute, network).
* Self-service console for simple and advanced use cases.
* Built on KVM hypervisor.
* Enhanced security: SELinux and Mandatory Access Control for VMs and hypervisor.
* Scalability: up to 64 vCPU and 2TB vRAM per guest.
* iSCSI, FC, NFS, and local storage.
* Memory overcommit support (Kernel Samepage Merging).
* Developer SDK for ovirt-engine, written in Python.
