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


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

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


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:

For deeper understanding of why you might need this tool, read the section "FIXED APPLIANCE" below.

Instead of running this tool, you can download fixed appliances from These appliances were made using this tool.

There are two ways to use this tool.



Display short usage information and exit.


Display the version number and exit.


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.


When libguestfs (or libguestfs tools) are run, they search a path looking for an appliance. The path is built into libguestfs, or can be set using the LIBGUESTFS_PATH environment variable.

Normally a supermin appliance is located on this path (see "SUPERMIN APPLIANCE" in supermin(1)). libguestfs reconstructs this into a full appliance by running supermin --build.

However, a simpler "fixed appliance" can also be used. libguestfs detects this by looking for a directory on the path containing four files called kernel, initrd, root and README.fixed (note the README.fixed file must be present as well).

If the fixed appliance is found, libguestfs skips supermin entirely and just runs qemu with the kernel, initrd and root disk from the fixed appliance.

Thus the fixed appliance can be used when a platform or Linux distro does not support supermin. You build the fixed appliance on a platform that does support supermin, and copy it over, and use that to run libguestfs.


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).


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


For the full list of environment variables which may affect libguestfs, please see the guestfs(3) manual page.
