It also has bindings in many +popular high-level languages, including Perl, Python, Ruby, OCaml, +Java, PHP, and more. The library lets you write simple programs to +create, view and modify disk images, like the one in +Appendix~\ref{perlexample}. + +There are many tools which use libguestfs: + +\begin{itemize} +\item[{\bf guestfish}] +Interactive and scriptable shell. +\item[{\bf guestmount}] +Mount filesystems from any guest or disk image on the host. +\item[{\bf virt-alignment-scan}] +Check alignment of partitions in guests. +\item[{\bf virt-cat}] +Display a file from a guest. +\item[{\bf virt-copy-in}] +Copy files and directories into a guest. +\item[{\bf virt-copy-out}] +Copy files and directories out of a guest. +\item[{\bf virt-df}] +Display disk usage of a guest. +\item[{\bf virt-edit}] +Edit a file in a guest. +\item[{\bf virt-filesystems}] +Display the partitions, filesystems, logical volumes etc. in a guest. +\item[{\bf virt-inspector}] +Inspect a guest and produce a report detailing the operating system, +version, applications installed and more. +\item[{\bf virt-ls}] +List files and directories in a guest. +\item[{\bf virt-make-fs}] +Make a new filesystem. +\item[{\bf virt-rescue}] +Rescue mode for guests. +\item[{\bf virt-resize}] +Resize a guest. +\item[{\bf virt-sparsify}] +Make a disk sparse. +\item[{\bf virt-sysprep}] +Reset a guest to ``factory configuration''. +\item[{\bf virt-tar-in}] +Copy files from a tarball into a guest. +\item[{\bf virt-tar-out}] +Copy files out of a guest into a tarball. +\item[{\bf virt-win-reg}] +Display and edit the Windows Registry in a guest. +\end{itemize} + +and libguestfs is increasingly being used by major projects: + +\begin{itemize} +\item[{\bf BoxGrinder \& Oz}] +Projects that can create guests from scratch. +\item[{\bf OpenStack}] +Uses libguestfs to inject files into guests. +\item[{\bf virt-manager}] +Uses libguestfs to display icons and applications in guests. +\item[{\bf virt-v2v \& virt-p2v}] +Migrate between physical machines and different hypervisors. +\end{itemize} + +\section{Using guestfish to view and inject files} + +An easy way to get started with libguestfs is to use our shell +scripting tool, +{\em guestfish}\footnote{\url{http://libguestfs.org/guestfish.1.html}} +to open up a disk image and look inside. + +You can open up almost any type of disk image, such as a raw file, +qcow2 file, or a logical volume or partition that contains a virtual +machine. You {\em don't} need to be root, unless you need root to +access the device. + +Simply do: + +\begin{samepage} +\begin{verbatim} +$ guestfish -a disk.img -i + +Welcome to guestfish, the libguestfs filesystem interactive shell for +editing virtual machine filesystems. + +Type: 'help' for help on commands + 'man' to read the manual + 'quit' to quit the shell + +Operating system: Red Hat Enterprise Linux Server release 6.3 (Santiago) +/dev/vg_rhel6x32/lv_root mounted on / +/dev/sda1 mounted on /boot +\end{verbatim} +\end{samepage} + +You can now use guestfish commands to list files and directories and +create files: + +\begin{samepage} +\begin{verbatim} +> ls / +bin +boot +cgroup +[etc] + +> write-append /etc/rc.d/rc.local "service sshd start" + +> cat /etc/rc.d/rc.local +#!/bin/sh +touch /var/lock/subsys/local +service sshd start +\end{verbatim} +\end{samepage} + +Some useful commands include: + +\begin{itemize} +\item[\texttt{cat}] Display small text files. +\item[\texttt{edit}] Edit a file. +\item[\texttt{less}] Display longer files. +\item[\texttt{ll}] List (long) directory. +\item[\texttt{ls}] List directory. +\item[\texttt{mkdir}] Make a directory. +\item[\texttt{rm}] Remove a file. +\item[\texttt{touch}] Touch a file. +\item[\texttt{upload}] Upload a local file to the disk. +\item[\texttt{write}] Create a file with content. +\end{itemize} + +As there are hundreds of commands, it's a good idea to read the +{\em guestfish(1)} and +{\em guestfs(3)}\footnote{\url{http://libguestfs.org/guestfs.3.html}} +man pages. These are also available online at the +website\footnote{\url{http://libguestfs.org}}. + +\section{Introducing virt-rescue} + +virt-rescue\footnote{\url{http://libguestfs.org/virt-rescue.1.html}} +is a good way to rescue virtual machines that don't boot, or just +generally make ad hoc changes to virtual machines. It's like a rescue +CD for virtual machines. + +virt-rescue is a little different from guestfish in that you get an +ordinary shell and ordinary tools. However unlike guestfish, +virt-rescue cannot be used from shell scripts, so it's not useful if +you want to make repeatable changes to lots of your guests. + +You must not use virt-rescue on running VMs. + +If you had a libvirt guest called ``Fedora'' then: + +\begin{samepage} +\begin{verbatim} +# virt-rescue -d Fedora +[lots of boot messages] + +Welcome to virt-rescue, the libguestfs rescue shell. + +Note: The contents of / are the rescue appliance. +You have to mount the guest's partitions under /sysroot +before you can examine them. + +> lvs + LV VG Attr LSize Origin Snap% Move Log Copy% Convert + lv_root vg_f13x64 -wi-a- 7.56g + lv_swap vg_f13x64 -wi-a- 1.94g +> mount /dev/vg_f13x64/lv_root /sysroot/ +[ 107.912813] EXT4-fs (dm-0): mounted filesystem with ordered data mode. +Opts: (null) +> ls -l /sysroot/etc/fstab +-rw-r--r--. 1 root root 781 Sep 16 2010 /sysroot/etc/fstab +> vi /sysroot/etc/fstab +\end{verbatim} +\end{samepage} + +There is a lot more information about virt-rescue in the +man page {\em virt-rescue(1)}. + +\section{New features in libguestfs 1.20} + +At the end of this year (2012) we hope to make a major new release of +libguestfs. Since the last version was released in May 2012, this +represents over 6 months of development effort, and it includes and +uses some major new features from KVM. + +The new version will (optionally) use libvirt to manage the libguestfs +appliance.
