libguestfs-make-fixed-appliance(1)

NAME

   libguestfs-make-fixed-appliance - Make a "fixed appliance" for
   libguestfs

SYNOPSIS

    libguestfs-make-fixed-appliance [--options] OUTPUTDIR

    libguestfs-make-fixed-appliance [--options] --xz

DESCRIPTION

   libguestfs-make-fixed-appliance lets you make a pre-built binary
   appliance for libguestfs.

   Note that ordinary users should not need to run this tool.

   Some reasons why you might want to use this include:

   *   You want to make a self-contained libguestfs appliance that can be
       copied to another machine or platform that doesn't support
       supermin(1).

   *   You have multiple users on the same machine and want to avoid the
       storage duplication and start-up overhead of having multiple cached
       copies of the appliance.

   *   You want to have very predictable performance from libguestfs (see
       guestfs-performance(1)).

   For deeper understanding of why you might need this tool, read "FIXED
   APPLIANCE" in guestfs-internals(1).

   Instead of running this tool, you can download fixed appliances from
   http://libguestfs.org/download/binaries/appliance/.  These appliances
   were made using this tool.

   There are two ways to use this tool.

   *   Specify an output directory, for example:

        libguestfs-make-fixed-appliance /usr/local/lib/guestfs/appliance

       The output directory is created if it does not exist.  Four files
       are created in this directory:

        <OUTPUTDIR>/kernel
        <OUTPUTDIR>/initrd
        <OUTPUTDIR>/root
        <OUTPUTDIR>/README.fixed

       Note that "OUTPUTDIR/root" is a sparse file, so take care when
       copying it.

       You can then run libguestfs (possibly after copying this directory
       to another machine) by setting the environment variable
       LIBGUESTFS_PATH to "OUTPUTDIR".

   *   The alternative method is to use the --xz option to create a
       compressed tarball:

        libguestfs-make-fixed-appliance --xz

       This creates a tarball in the current directory called:

        appliance-<VERSION>.tar.xz

       (where "VERSION" is the version of libguestfs).  The tarball
       contains the four files:

        appliance/kernel
        appliance/initrd
        appliance/root
        appliance/README.fixed

       Note that "appliance/root" is a sparse file, so take care when
       copying it.

OPTIONS

   --help
       Display short usage information and exit.

   -V
   --version
       Display the version number and exit.

   --xz
       Instead of creating the appliance in an output directory, create a
       compressed tarball of the appliance in the current directory called
       appliance-VERSION.tar.xz where "VERSION" is the version of
       libguestfs.

       Using --xz can take some time.  If working normally, the tool is
       completely silent when it is running.

LICENSING

   The fixed appliance is a complete Linux binary distro.  If you
   distribute it, you may need to distribute corresponding source files to
   remain in legal compliance with the licenses of the software in the
   appliance (such as the GNU General Public License).

EXIT STATUS

   libguestfs-make-fixed-appliance returns 0 if the appliance was built
   without errors.

ENVIRONMENT VARIABLES

   For the full list of environment variables which may affect libguestfs,

Opportunity

Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.

Free Software

Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
