ОПИС¶

libguestfs-make-fixed-appliance lets you make a pre-built binary appliance for libguestfs. Зауважте, що у звичайних користувачів не повинно виникнути потреби у запуску цієї програми. 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 the section "FIXED APPLIANCE" below. Instead of running this tool, you can download fixed appliances from http://libguestfs.org/download/binaries/appliance/. These appliances were made using this tool. Передбачено два способи використання цього інструмента.

•

Вказати каталог виведення даних, приклад:

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

Якщо каталогу виведення даних ще не існує, його буде створено. У цьому каталозі буде створено чотири файли:

 <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
    

Буде створено архів у поточному каталозі з назвою:

 appliance-<ВЕРСІЯ>.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.

--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.

ФІКСОВАНА ОСНОВНА СИСТЕМА¶

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.

УМОВИ ЛІЦЕНЗУВАННЯ¶

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).

СТАН ВИХОДУ¶

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