Command line tools

guestfish

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

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

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

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

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

Watch the CPU, memory, network and disk utilization of all virtual machines running on a host.

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

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

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

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

vms is a tool wrapping around the libvirt API to manage multiple virtual machines at once with name patterns.

Configuration Management

LCFG

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

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

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

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

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

Part of the virt-goodies package, vmware2libvirt is a python script for migrating a vmware image to libvirt.

Desktop applications

virt-manager

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.

OpenStack

OpenStack is a "cloud operating system" usable for both public and 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

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

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

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.

Libraries

libguestfs

A library and set of tools for accessing and modifying virtual machine disk images. It can be linked with C and C++ management programs, and has bindings for Perl, Python, Ruby, Java, OCaml, PHP, Haskell, and C#. Using its FUSE module, you can also mount guest filesystems on the host, and there is a subproject to allow merging changes into the Windows Registry in Windows guests.

libvirt-sandbox

A library and command line tools for simplifying the creation of application sandboxes using virtualization technology. It currently supports either KVM, QEMU or LXC as backends. Integration with systemd facilitates sandboxing of system services like apache.

Ruby Libvirt Object bindings

Allows using simple ruby objects to manipulate hypervisors, guests, storage, network etc. It is based on top of the native ruby bindings.

LiveCD / Appliances

virt-p2v

An older tool for converting a physical machine into a virtual machine. 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.

Monitoring

collectd

The libvirt-plugin is part of collectd and gathers statistics about virtualized guests on a system. This way, you can collect CPU, network interface and block device usage for each guest without installing collectd on the guest systems. For a full description, please refer to the libvirt section in the collectd.conf(5) manual page.

Host sFlow

Provisioning

Foreman

Foreman is an open source web based application aimed to be a Single Address For All Machines Life Cycle Management. Foreman:

  • Creates everything you need when adding a new machine to your network, its goal being automatically managing everything you would normally manage manually (DNS, DHCP, TFTP, Virtual 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.
