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

This plugin for Jenkins adds a way to control guest domains hosted
on Xen or QEMU/KVM. You configure a Jenkins Slave,
selecting the guest domain and hypervisor. When you need to build a
job on a specific Slave, 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.
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

the guest. (Note this tool is included with libguestfs)
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.
