This tool allows you to discover filesystems, partitions, logical volumes,
and their sizes in a disk image or virtual machine. It is a replacement for
\&\fIvirt\-list\-filesystems\fR\|(1) and \fIvirt\-list\-partitions\fR\|(1).
.PP
One use for this tool is from shell scripts to iterate over all filesystems
from a disk image:
.PP
.Vb 3
\& for fs in $(virt\-filesystems \-a disk.img); do
\& # ...
\& done
.Ve
.PP
Another use is to list partitions before using another tool to modify those
partitions (such as \fIvirt\-resize\fR\|(1)). If you are curious about what an
unknown disk image contains, use this tool along with \fIvirt\-inspector\fR\|(1).
.PP
Various command line options control what this program displays. You need
to give either \fI\-a\fR or \fI\-d\fR options to specify the disk image or libvirt
guest respectively. If you just specify that then the program shows
filesystems found, one per line, like this:
.PP
.Vb 3
\& $ virt\-filesystems \-a disk.img
\& /dev/sda1
\& /dev/vg_guest/lv_root
.Ve
.PP
Якщо ви додасте \fI\-l\fR або \fI\-\-long\fR, у виведених даних буде показано
додаткову інформацію:
.PP
.Vb 4
\& $ virt\-filesystems \-a disk.img \-l
\& Name Type VFS Label Size
\& /dev/sda1 filesystem ext4 boot 524288000
\& /dev/vg_guest/lv_root filesystem ext4 root 10212081664
.Ve
.PP
If you add \fI\-\-extra\fR then non-mountable (swap, unknown) filesystems are
shown as well:
.PP
.Vb 5
\& $ virt\-filesystems \-a disk.img \-\-extra
\& /dev/sda1
\& /dev/vg_guest/lv_root
\& /dev/vg_guest/lv_swap
\& /dev/vg_guest/lv_data
.Ve
.PP
If you add \fI\-\-partitions\fR then partitions are shown instead of filesystems:
.PP
.Vb 3
\& $ virt\-filesystems \-a disk.img \-\-partitions
\& /dev/sda1
\& /dev/sda2
.Ve
.PP
Similarly you can use \fI\-\-logical\-volumes\fR, \fI\-\-volume\-groups\fR,
\&\fI\-\-physical\-volumes\fR, \fI\-\-block\-devices\fR to list those items.
.PP
You can use these options in combination as well (if you want a combination
including filesystems, you have to add \fI\-\-filesystems\fR). Notice that some
items fall into several categories (eg. \f(CW\*(C`/dev/sda1\*(C'\fR might be both a
partition and a filesystem). These items are listed several times. To get
a list which includes absolutely everything that virt-filesystems knows
about, use the \fI\-\-all\fR option.
.PP
UUIDs (because they are quite long) are not shown by default. Add the
\&\fI\-\-uuid\fR option to display device and filesystem UUIDs in the long output.
.PP
\&\fI\-\-all \-\-long \-\-uuid\fR is a useful combination to display all possible
information about everything.
.PP
.Vb 7
\& $ virt\-filesystems \-a win.img \-\-all \-\-long \-\-uuid \-h
\& Name Type VFS Label Size Parent UUID

\& /dev/sda2 partition \- \- 20G /dev/sda \-
\& /dev/sda device \- \- 20G \- \-

.PP
For machine-readable output, use \fI\-\-csv\fR to get Comma-Separated Values.

Add \fIfile\fR which should be a disk image from a virtual machine. If the
virtual machine has multiple block devices, you must supply all of them with
separate \fI\-a\fR options.

The format of the disk image is auto-detected. To override this and force a

.IP "\fB\-\-echo\-keys\fR" 4
.IX Item "--echo-keys"
When prompting for keys and passphrases, virt-filesystems normally turns
echoing off so you cannot see what you are typing. If you are not worried
about Tempest attacks and there is no one else in the room you can specify
this flag to see what you are typing.
.IP "\fB\-\-extra\fR" 4
.IX Item "--extra"
This causes filesystems that are not ordinary, mountable filesystems to be
displayed. This category includes swapspace, and filesystems that are empty
or contain unknown data.
.Sp
This option implies \fI\-\-filesystems\fR.
.IP "\fB\-\-filesystems\fR" 4
.IX Item "--filesystems"
Display mountable filesystems. If no display option was selected then this
option is implied.

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\fR with no argument switches back to
auto-detection for subsequent \fI\-a\fR options.
.Sp

If you have untrusted raw-format guest disk images, you should use this

The extra columns displayed depend on what output you select, and the
ordering of columns may change in future versions. Use the title row,
\&\fI\-\-csv\fR output and/or \fIcsvtool\fR\|(1) to match columns to data in external
programs.

For device and partition names these are displayed as canonical libguestfs
names, so that for example \f(CW\*(C`/dev/sda2\*(C'\fR is the second partition on the first
device.

The size of the object in bytes. If the \fI\-\-human\fR option is used then the
size is displayed in a human-readable form.
.IP "\fBОснова\fR" 4
.IX Item "Основа"
The parent column records the parent relationship between objects.
.Sp
For example, if the object is a partition, then this column contains the
name of the containing device. If the object is a logical volume, then this
column is the name of the volume group.
.Sp
If there is more than one parent, then this column is (internal to the
column) a comma-separated list, eg. \f(CW\*(C`/dev/sda,/dev/sdb\*(C'\fR.
.IP "\fB\s-1UUID\s0\fR" 4
.IX Item "UUID"
If the object has a \s-1UUID\s0 (used for identifying and mounting filesystems and
block devices) then this column contains the \s-1UUID\s0 as a string.

The \s-1UUID\s0 is only displayed if the \fI\-\-uuid\fR option is given.
