.SH "警告"
.IX Header "警告"
You must \fInot\fR use \f(CW\*(C`virt\-tar\*(C'\fR with the \fI\-u\fR option (upload) on live
virtual machines.  If you do this, you risk disk corruption in the \s-1VM.\s0
\&\f(CW\*(C`virt\-tar\*(C'\fR tries to stop you from doing this, but doesn't catch all cases.
.PP
You can use \fI\-x\fR (extract) on live virtual machines, but you might get
inconsistent results or errors if there is filesystem activity inside the
\&\s-1VM.\s0  If the live \s-1VM\s0 is synched and quiescent, then \f(CW\*(C`virt\-tar\*(C'\fR will usually
work, but the only way to guarantee consistent results is if the virtual
machine is shut down.
.SH "説明"
.IX Header "説明"
\&\f(CW\*(C`virt\-tar\*(C'\fR 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.
.PP
If you want to just view a single file, use \fBvirt\-cat\fR\|(1).  If you just
want to edit a single file, use \fBvirt\-edit\fR\|(1).  For more complex cases you
should look at the \fBguestfish\fR\|(1) tool.
.PP
There are two modes of operation: \fI\-x\fR (eXtract) downloads a directory and
its contents (recursively) from the virtual machine into a local tarball.
\&\fI\-u\fR uploads from a local tarball, unpacking it into a directory inside the
virtual machine.  You cannot use these two options together.
.PP
In addition, you may need to use the \fI\-z\fR (gZip) option to enable
compression.  When uploading, you have to specify \fI\-z\fR if the upload file
is compressed because virt-tar won't detect this on its own.
.PP
\&\f(CW\*(C`virt\-tar\*(C'\fR 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 \fBlibguestfs\fR\|(3) \s-1API\s0).
.SH "オプション"
.IX Header "オプション"
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
簡単なヘルプを表示します。
.IP "\fB\-\-version\fR" 4
.IX Item "--version"
バージョン番号を表示して、終了します。
.IP "\fB\-c \s-1URI\s0\fR" 4
.IX Item "-c URI"
.PD 0
.IP "\fB\-\-connect \s-1URI\s0\fR" 4
.IX Item "--connect URI"
.PD
libvirt を使用していると、指定された \fI\s-1URI\s0\fR に接続します。  省略すると、デフォルトの libvirt ハイパーバイザーに接続します。
.Sp
仮想マシンのブロックデバイスを直接指定すると、libvirt はまったく使用されません。
.IP "\fB\-\-format\fR raw" 4
.IX Item "--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.
.Sp
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.
.Sp
If working with untrusted raw-format guest disk images, you should ensure
the format is always specified.
.IP "\fB\-x\fR" 4
.IX Item "-x"
.PD 0
.IP "\fB\-\-extract\fR" 4
.IX Item "--extract"
.IP "\fB\-\-download\fR" 4
.IX Item "--download"
.IP "\fB\-u\fR" 4
.IX Item "-u"
.IP "\fB\-\-upload\fR" 4
.IX Item "--upload"
.PD
仮想マシンからローカル tar ファイルにディレクトリを展開 (ダウンロード) するには \fI\-x\fR を使用します。
.Sp
ローカル tar ファイルから仮想マシンの中にアップロードおよび展開するには \fI\-u\fR を使用します。このオプションを使用する前に \*(L"警告\*(R"
セクションを参照してください。
.Sp
これらのオプションのいずれかを正確に指定する必要があります。
.IP "\fB\-z\fR" 4
.IX Item "-z"
.PD 0
.IP "\fB\-\-gzip\fR" 4
.IX Item "--gzip"
.PD
入力または出力 tar ファイルを gzip 圧縮するよう指定します。
