       virt-tar - Extract or upload files to a virtual machine

КОРОТКИЙ ОПИС

        virt-tar [--options] -x domname directory tarball

        virt-tar [--options] -u domname tarball directory

        virt-tar [--options] disk.img [disk.img ...] -x directory tarball

        virt-tar [--options] disk.img [disk.img ...] -u tarball directory

ЗАСТАРІЛЕ

       This tool is obsolete.  Use virt-copy-in(1), virt-copy-out(1), virt-tar-in(1),
       virt-tar-out(1) as replacements.

ПРИКЛАДИ

       Download "/home" from the VM into a local tarball:

        virt-tar -x domname /home home.tar

        virt-tar -zx domname /home home.tar.gz

       Upload a local tarball and unpack it inside "/tmp" in the VM:

        virt-tar -u domname uploadstuff.tar /tmp

        virt-tar -zu domname uploadstuff.tar.gz /tmp

ПОПЕРЕДЖЕННЯ

       You must not use "virt-tar" with the -u option (upload) on live virtual machines.  If you
       do this, you risk disk corruption in the VM.  "virt-tar" tries to stop you from doing
       this, but doesn't catch all cases.

       You can use -x (extract) on live virtual machines, but you might get inconsistent results
       or errors if there is filesystem activity inside the VM.  If the live VM is synched and
       quiescent, then "virt-tar" will usually work, but the only way to guarantee consistent
       results is if the virtual machine is shut down.

ОПИС

       "virt-tar" is a general purpose archive tool for downloading and uploading parts of a
       guest filesystem.  There are many possibilities: making backups, uploading data files,
       snooping on guest activity, fixing or customizing guests, etc.

       If you want to just view a single file, use virt-cat(1).  If you just want to edit a
       single file, use virt-edit(1).  For more complex cases you should look at the guestfish(1)
       tool.

       There are two modes of operation: -x (eXtract) downloads a directory and its contents
       (recursively) from the virtual machine into a local tarball.  -u uploads from a local
       tarball, unpacking it into a directory inside the virtual machine.  You cannot use these
       two options together.

       In addition, you may need to use the -z (gZip) option to enable compression.  When
       uploading, you have to specify -z if the upload file is compressed because virt-tar won't
       detect this on its own.

       "virt-tar" can only handle tar (optionally gzipped) format tarballs.  For example it
       cannot do PKZip files or bzip2 compression.  If you want that then you'll have to rebuild
       the tarballs yourself.  (This is a limitation of the libguestfs(3) API).

       -c адреса
       --connect адреса
           Якщо використовується libvirt, встановити з’єднання з вказаним URI. Якщо пропущено,
           з’єднання буде встановлено з типовим гіпервізором libvirt.

           Якщо вказати блокові пристрої гостьових систем безпосередньо, libvirt не буде
           використовуватися взагалі.

       --format raw
           Specify the format of disk images given on the command line.  If this is omitted then
           the format is autodetected from the content of the disk image.

           If disk images are requested from libvirt, then this program asks libvirt for this
           information.  In this case, the value of the format parameter is ignored.

           If working with untrusted raw-format guest disk images, you should ensure the format
           is always specified.

       -x
       --extract
       --download
       -u
       --upload
           Use -x to extract (download) a directory from a virtual machine to a local tarball.

           Use -u to upload and unpack from a local tarball into a virtual machine.  Please read
           the "WARNING" section above before using this option.

           You must specify exactly one of these options.

       -z
       --gzip
           Specify that the input or output tarball is gzip-compressed.

ЕКРАНУВАННЯ СИМВОЛІВ У ОБОЛОНЦІ

       Libvirt guest names can contain arbitrary characters, some of which have meaning to the
       shell such as "#" and space.  You may need to quote or escape these characters on the
       command line.  See the shell manual page sh(1) for details.
