libvirt is a collection of open source tools for managing virtual machines on a host system . This consists of a programming interface (API), a daemon ( libvirtd ) and a command line program ( virsh ). With the help of libvirt it is possible to control hypervisor technologies from different manufacturers such as KVM / QEMU , Xen , VMware , VirtualBox or Hyper-V and to operate them via a uniform interface.

history

The first version of libvirt was announced in December 2005 on the libvir-list mailing list (then still under the name libvir ). This already contained a rudimentary connection to Python , but initially only worked with the Xen hypervisor. However, it was already planned to support other virtualization technologies. In February 2006 the project was renamed from libvir to libvirt and in March of the same year the first version for the connection via Perl was published . In August 2006, the first-time support for the QEMU hypervisor was introduced. In November 2007 the Ruby connection was added, and work began on making libvirt executable under Windows in the Cygwin environment. In 2009, patches were added with which the VirtualBox Hypervisor could be addressed, and in 2010 support for virtualization with VMware was added.

Technical specifications

libvirt is written in the C programming language and naturally also supports connection using C ++ and Python . The following additional programming languages ​​are also officially supported:

Supported hypervisors

libvirt supports a large number of hypervisors and is itself used as the basis for a number of management solutions.

Currently, around a dozen virtualization technologies can be used with libvirt. Including:

User interface

The command line program virsh is used to manage virtual machines and is part of libvirt. There is also the GUI program Virtual Machine Manager , which, like libvirt , is co-developed by Red Hat . The web application oVirt (also from Red Hat) largely relies on libvirt to provide the functionality offered.
