.SH "説明"
.IX Header "説明"
Virt-sysprep \*(L"resets\*(R" or \*(L"unconfigures\*(R" a virtual machine so that clones can
be made from it.  Steps in this process include removing \s-1SSH\s0 host keys,
removing persistent network \s-1MAC\s0 configuration, and removing user accounts.
Each step can be enabled or disabled as required.
.PP
Virt-sysprep modifies the guest or disk image \fIin place\fR.  The guest must
be shut down.  If you want to preserve the existing contents of the guest,
you \fImust copy or clone the disk first\fR.  See \*(L"\s-1COPYING\s0 \s-1AND\s0 \s-1CLONING\s0\*(R"
below.
.PP
You do \fInot\fR need to run virt-sysprep as root.  In fact we'd generally
recommend that you don't.  The time you might want to run it as root is when
you need root in order to access the disk image, but even in this case it
would be better to change the permissions on the disk image to be writable
as the non-root user running virt-sysprep.
.PP
\&\*(L"Sysprep\*(R" stands for \*(L"system preparation\*(R" tool.  The name comes from the
Microsoft program \f(CW\*(C`sysprep.exe\*(C'\fR which is used to unconfigure Windows
machines in preparation for cloning them.  Having said that, virt-sysprep
does \fInot\fR currently work on Microsoft Windows guests.  We plan to support
Windows sysprepping in a future version, and we already have code to do it.

.IP "\fB\-\-enable\fR operations" 4
.IX Item "--enable operations"
Choose which sysprep operations to perform.  Give a comma-separated list of
operations, for example:
.Sp
.Vb 1

.Ve
.Sp
would enable \s-1ONLY\s0 \f(CW\*(C`ssh\-hostkeys\*(C'\fR and \f(CW\*(C`udev\-persistent\-net\*(C'\fR operations.
.Sp
If the \fI\-\-enable\fR option is not given, then we default to trying most
sysprep operations (see \fI\-\-list\-operations\fR to show which are enabled).
.Sp
Regardless of the \fI\-\-enable\fR option, sysprep operations are skipped for

The default for the \fI\-a\fR option is to auto-detect the format of the disk
image.  Using this forces the disk format for \fI\-a\fR options which follow on
the command line.  Using \fI\-\-format auto\fR switches back to auto-detection
for subsequent \fI\-a\fR options.
.Sp
例:
.Sp
.Vb 1
\& virt\-sysprep \-\-format raw \-a disk.img
.Ve
.Sp
\&\f(CW\*(C`disk.img\*(C'\fR に対してローイメージを強制します（自動検出しません）。
.Sp

.Ve
.Sp
\&\f(CW\*(C`disk.img\*(C'\fR に対してロー形式（自動検知なし）を強制し、\f(CW\*(C`another.img\*(C'\fR に対して自動検知に戻します。
.Sp
仮想マシンのディスクイメージが信頼できないロー形式であるならば、ディスク形式を指定するためにこのオプションを使用すべきです。これにより、悪意のある仮想マシンにより起こり得るセキュリティ問題を回避できます
(\s-1CVE\-2010\-3851\s0)。

.Sp
The first field is the operation name, which can be supplied to

If the \fI\-\-enable\fR option is \fInot\fR given, then most sysprep operations are
enabled.

Use \f(CW\*(C`virt\-sysprep \-\-list\-operations\*(C'\fR to list all operations for your

Operations can be individually enabled using the \fI\-\-enable\fR option.  Use a

.SS "\fBscript\fP *"
.IX Subsection "script *"
Run arbitrary scripts against the guest.
.PP
The \f(CW\*(C`script\*(C'\fR module lets you run arbitrary shell scripts or programs
against the guest.
.PP
Note this feature requires \s-1FUSE\s0 support.  You may have to enable this in
your host, for example by adding the current user to the \f(CW\*(C`fuse\*(C'\fR group, or
by loading a kernel module.
.PP
Use one or more \fI\-\-script\fR parameters to specify scripts or programs that
will be run against the guest.
.PP
The script or program is run with its current directory being the guest's
root directory, so relative paths should be used.  For example: \f(CW\*(C`rm
etc/resolv.conf\*(C'\fR in the script would remove a Linux guest's \s-1DNS\s0
configuration file, but \f(CW\*(C`rm /etc/resolv.conf\*(C'\fR would (try to) remove the
host's file.
.PP
Normally a temporary mount point for the guest is used, but you can choose a
specific one by using the \fI\-\-scriptdir\fR parameter.

Use the block device as a backing file and create a snapshot on top for each
guest.  The advantage is that you don't need to copy the block device (very
fast) and only changes are stored (less storage required).

Note that writing to the backing file once you have created guests on top of

Tools that can do this include: \fIqemu\-img\fR\|(1) (with the \fIcreate \-f qcow2
\&\-o backing_file\fR option), \fIlvcreate\fR\|(8) (\fI\-\-snapshot\fR option).  Some
filesystems (such as btrfs) and most Network Attached Storage devices can
also create cheap snapshots from files or LUNs.

.SS "virt-clone"
.IX Subsection "virt-clone"
A separate tool, \fIvirt\-clone\fR\|(1), can be used to duplicate the block device
and/or modify the external libvirt configuration of a guest.  It will reset
the name, \s-1UUID\s0 and \s-1MAC\s0 address of the guest in the libvirt \s-1XML\s0.
.PP
\&\fIvirt\-clone\fR\|(1) does not use libguestfs and cannot look inside the disk
image.  This was the original motivation to write virt-sysprep.

\&\fIvirt\-sparsify\fR\|(1) can be used to make the cloning template smaller, making
it easier to compress and/or faster to copy.
.PP
Notice that since virt-sparsify also copies the image, you can use it to
make the initial copy (instead of \f(CW\*(C`dd\*(C'\fR).

If you want to give people cloned guests, but let them pick the size of the
guest themselves (eg. depending on how much they are prepared to pay for
disk space), then instead of copying the template, you can run
\&\fIvirt\-resize\fR\|(1).  Virt-resize performs a copy and resize, and thus is
ideal for cloning guests from a template.
.SH "セキュリティ"
.IX Header "セキュリティ"
Although virt-sysprep removes some sensitive information from the guest, it
does not pretend to remove all of it.  You should examine the \*(L"\s-1OPERATIONS\s0\*(R"
above and the guest afterwards.
.PP
Sensitive files are simply removed.  The data they contained may still exist
on the disk, easily recovered with a hex editor or undelete tool.  Use
\&\fIvirt\-sparsify\fR\|(1) as one way to remove this content.  See also the
\&\fIscrub\fR\|(1) command to get rid of deleted content in directory entries and
inodes.
.SS "乱数の種"
.IX Subsection "乱数の種"
\&\fI(このセクションは Linux 仮想マシンのみに適用します)\fR
.PP
The virt-sysprep \f(CW\*(C`random\-seed\*(C'\fR operation writes a few bytes of randomness
from the host into the guest's random seed file.
.PP
If this is just done once and the guest is cloned from the same template,
then each guest will start with the same entropy, and things like \s-1SSH\s0 host
keys and \s-1TCP\s0 sequence numbers may be predictable.
.PP
Therefore you should arrange to add more randomness \fIafter\fR cloning from a
template too, which can be done by just enabling the \f(CW\*(C`random\-seed\*(C'\fR
operation:
.PP
.Vb 2
\& cp template.img newguest.img

\&\fI(このセクションは SELinux を使用している Linux 仮想マシンのみに適用されます。)\fR
.PP
If any new files are created by virt-sysprep, then virt-sysprep touches
\&\f(CW\*(C`/.autorelabel\*(C'\fR so that these will be correctly labelled by SELinux the
next time the guest is booted.  This process interrupts boot and can take
some time.

.SH "SHELL QUOTING"

Libvirt guest names can contain arbitrary characters, some of which have
meaning to the shell such as \f(CW\*(C`#\*(C'\fR and space.  You may need to quote or
escape these characters on the command line.  See the shell manual page
\&\fIsh\fR\|(1) for details.
