Applications using libvirt
==========================
This page provides an illustration of the wide variety of applications
using the libvirt management API.
.. contents::
Add an application
------------------
To add an application not listed on this page, send a message to the
`mailing list <contact.html>`__, requesting it be added here, or simply
send a patch against the documentation in the libvirt.git docs
subdirectory. If your application uses libvirt as its API, the following
graphics are available for your website to advertise support for
libvirt:

Command line tools
------------------
`guestfish <https://libguestfs.org>`__
Guestfish is an interactive shell and command-line tool for examining
and modifying virtual machine filesystems. It uses libvirt to find
guests and their associated disks.
virsh
An interactive shell, and batch scriptable tool for performing
management tasks on all libvirt managed domains, networks and
storage. This is part of the libvirt core distribution.
`virt-clone <https://virt-manager.org/>`__
Allows the disk image(s) and configuration for an existing virtual
machine to be cloned to form a new virtual machine. It automates
copying of data across to new disk images, and updates the UUID, MAC
address, and name in the configuration.
`virt-df <https://people.redhat.com/rjones/virt-df/>`__
Examine the utilization of each filesystem in a virtual machine from
the comfort of the host machine. This tool peeks into the guest disks
and determines how much space is used. It can cope with common Linux
filesystems and LVM volumes.
`virt-image <https://virt-manager.org/>`__
Provides a way to deploy virtual appliances. It defines a simplified
portable XML format describing the pre-requisites of a virtual
machine. At time of deployment this is translated into the domain XML
format for execution under any libvirt hypervisor meeting the
pre-requisites.
`virt-install <https://virt-manager.org/>`__
Provides a way to provision new virtual machines from a OS
distribution install tree. It supports provisioning from local CD
images, and the network over NFS, HTTP and FTP.
`virt-top <https://people.redhat.com/rjones/virt-top/>`__
Watch the CPU, memory, network and disk utilization of all virtual
machines running on a host.
`virt-what <https://people.redhat.com/~rjones/virt-what/>`__
virt-what is a shell script for detecting if the program is running
in a virtual machine. It prints out a list of facts about the virtual
machine, derived from heuristics.
`stap <https://sourceware.org/systemtap/>`__
SystemTap is a tool used to gather rich information about a running
system through the use of scripts. Starting from v2.4, the front-end
application stap can use libvirt to gather data within virtual
machines.
`vagrant-libvirt <https://github.com/pradels/vagrant-libvirt/>`__
Vagrant-Libvirt is a Vagrant plugin that uses libvirt to manage
virtual machines. It is a command line tool for developers that makes
it very fast and easy to deploy and re-deploy an environment of vm's.
`virt-lightning <https://github.com/virt-lightning/virt-lightning>`__
Virt-Lightning uses libvirt, cloud-init and libguestfs to allow
anyone to quickly start a new VM. Very much like a container CLI, but
with a virtual machine.
`vms <https://github.com/cbosdo/vms>`__
vms is a tool wrapping around the libvirt API to manage multiple virtual
machines at once with name patterns.
Configuration Management
------------------------
`LCFG <https://wiki.lcfg.org/bin/view/LCFG/LcfgLibvirt>`__
LCFG is a system for automatically installing and managing the
configuration of large numbers of Unix systems. It is particularly
suitable for sites with very diverse and rapidly changing
configurations.
The lcfg-libvirt package adds support for virtualized systems to
LCFG, with both Xen and KVM known to work. Cloning guests is
supported, as are the bridged, routed, and isolated modes for Virtual
Networking.
Continuous Integration
----------------------
`BuildBot <https://docs.buildbot.net/latest/manual/configuration/workers-libvirt.html>`__
BuildBot is a system to automate the compile/test cycle required by
most software projects. CVS commits trigger new builds, run on a
variety of client machines. Build status (pass/fail/etc) are
displayed on a web page or through other protocols.
`Jenkins <https://plugins.jenkins.io/libvirt-slave/>`__
This plugin for Jenkins adds a way to control guest domains hosted on
Xen or QEMU/KVM. You configure a Jenkins Agent, selecting the guest
domain and hypervisor. When you need to build a job on a specific
Agent, its guest domain is started, then the job is run. When the
build process is finished, the guest domain is shut down, ready to be
used again as required.
Conversion
----------
`virt-p2v <https://libguestfs.org/virt-p2v.1.html>`__
Convert a physical machine to run on KVM. It is a LiveCD which is
booted on the machine to be converted. It collects a little
information from the user, then copies the disks over to a remote
machine and defines the XML for a domain to run the guest. (Note this
tool is included with libguestfs)
`virt-v2v <https://libguestfs.org/virt-v2v.1.html>`__
virt-v2v converts guests from a foreign hypervisor to run on KVM,
managed by libvirt. It can convert guests from VMware or Xen to run
on OpenStack, oVirt (RHEV-M), or local libvirt. It will enable VirtIO
drivers in the converted guest if possible. (Note this tool is
included with libguestfs)
For RHEL customers of Red Hat, conversion of Windows guests is also
possible. This conversion requires some Microsoft signed pieces, that
Red Hat can provide.
`vmware2libvirt <https://launchpad.net/virt-goodies>`__
Part of the *virt-goodies* package, vmware2libvirt is a python script
for migrating a vmware image to libvirt.
Desktop applications
--------------------
`virt-manager <https://virt-manager.org/>`__
A general purpose desktop management tool, able to manage virtual
machines across both local and remotely accessed hypervisors. It is
targeted at home and small office usage up to managing 10-20 hosts
and their VMs.
`virt-viewer <https://virt-manager.org/>`__
A lightweight tool for accessing the graphical console associated
with a virtual machine. It can securely connect to remote consoles
supporting the VNC protocol. Also provides an optional mozilla
browser plugin.
`qt-virt-manager <https://f1ash.github.io/qt-virt-manager>`__
The Qt GUI for create and control VMs and another virtual entities
(aka networks, storages, interfaces, secrets, network filters).

private clouds. Its various parts take care of compute, storage and
networking resources and interface with the user using a dashboard.
Compute part uses libvirt to manage VM life-cycle, monitoring and so
on.
`KubeVirt <https://kubevirt.io/>`__
KubeVirt is a virtual machine management add-on for Kubernetes. The
aim is to provide a common ground for virtualization solutions on top
of Kubernetes.
`Cherrypop <https://github.com/gustavfranssonnyvell/cherrypop>`__
A cloud software with no masters or central points. Nodes autodetect
other nodes and autodistribute virtual machines and autodivide up the
workload. Also there is no minimum limit for hosts, well, one might
be nice. It's perfect for setting up low-end servers in a cloud or a
cloud where you want the most bang for the bucks.
`ZStack <https://en.zstack.io/>`__
ZStack is an open source IaaS software that aims to automate the
management of all resources (compute, storage, networking, etc.) in a
datacenter by using APIs, thus conforming to the principles of a
software-defined datacenter. The key strengths of ZStack in terms of
management are scalability, performance, and a fast, user-friendly
deployment.

Machines,CA, CMDB...)
- Integrates with Puppet (and acts as web front end to it).
- Takes care of provisioning until the point puppet is running,
allowing Puppet to do what it does best.
- Shows you Systems Inventory (based on Facter) and provides real
time information about hosts status based on Puppet reports.
Web applications

hypervisors. It delivers a number of functions, such as live
migration that allows for load balancing between cluster nodes,
monitoring CPU, memory.
`mist.io <https://mist.io/>`__
Mist.io is an open source project and a service that can assist you
