NAME

       virt-filesystems - List filesystems, partitions, block devices, LVM in
       a virtual machine or disk image

SYNOPSIS

        virt-filesystems [--options] -d domname

        virt-filesystems [--options] -a disk.img [-a disk.img ...]

DESCRIPTION

       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 virt-list-filesystems(1) and virt-list-partitions(1).

       One use for this tool is from shell scripts to iterate over all
       filesystems from a disk image:

        for fs in $(virt-filesystems -a disk.img); do
          # ...
        done

       Another use is to list partitions before using another tool to modify
       those partitions (such as virt-resize(1)).  If you are curious about
       what an unknown disk image contains, use this tool along with
       virt-inspector(1).

       Various command line options control what this program displays.  You
       need to give either -a or -d 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:

        $ virt-filesystems -a disk.img
        /dev/sda1
        /dev/vg_guest/lv_root

       If you add -l or --long then the output includes extra information:

        $ 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

       If you add --extra then non-mountable (swap, unknown) filesystems are
       shown as well:

        $ virt-filesystems -a disk.img --extra
        /dev/sda1
        /dev/vg_guest/lv_root
        /dev/vg_guest/lv_swap
        /dev/vg_guest/lv_data

       If you add --partitions then partitions are shown instead of
       filesystems:

        $ virt-filesystems -a disk.img --partitions
        /dev/sda1
        /dev/sda2

       Similarly you can use --logical-volumes, --volume-groups,
       --physical-volumes, --block-devices to list those items.

       You can use these options in combination as well (if you want a
       combination including filesystems, you have to add --filesystems).
       Notice that some items fall into several categories (eg. "/dev/sda1"
       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 --all option.

       UUIDs (because they are quite long) are not shown by default.  Add the
       --uuid option to display device and filesystem UUIDs in the long
       output.

       --all --long --uuid is a useful combination to display all possible
       information about everything.

        $ virt-filesystems -a win.img --all --long --uuid -h
        Name      Type       VFS  Label           Size Parent   UUID
        /dev/sda1 filesystem ntfs System Reserved 100M -        F81C92571C92112C
        /dev/sda2 filesystem ntfs -               20G  -        F2E8996AE8992E3B
        /dev/sda1 partition  -    -               100M /dev/sda -
        /dev/sda2 partition  -    -               20G  /dev/sda -
        /dev/sda  device     -    -               20G  -        -

       For machine-readable output, use --csv to get Comma-Separated Values.

OPTIONS

       --help
           Display brief help.

       -a file
       --add file
           Add file 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 -a options.

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

       -a URI
       --add URI
           Add a remote disk.  See "ADDING REMOTE STORAGE" in guestfish(1).

       --all
           Display everything.  This is currently the same as specifying these
           options: --filesystems, --extra, --partitions, --block-devices,
           --logical-volumes, --volume-groups, --physical-volumes.  (More may
           be added to this list in future).

           See also --long.

       --blkdevs
       --block-devices
           Display block devices.

       -c URI
       --connect URI
           If using libvirt, connect to the given URI.  If omitted, then we
           connect to the default libvirt hypervisor.

           If you specify guest block devices directly (-a), then libvirt is
           not used at all.

       --csv
           Write out the results in CSV format (comma-separated values).  This
           format can be imported easily into databases and spreadsheets, but
           read "NOTE ABOUT CSV FORMAT" below.

       -d guest
       --domain guest
           Add all the disks from the named libvirt guest.  Domain UUIDs can
           be used instead of names.

       --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.

       --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.

           This option implies --filesystems.

       --filesystems
           Display mountable filesystems.  If no display option was selected
           then this option is implied.

           With --extra, non-mountable filesystems are shown too.

       --format=raw|qcow2|..
       --format
           The default for the -a option is to auto-detect the format of the
           disk image.  Using this forces the disk format for -a options which
           follow on the command line.  Using --format with no argument
           switches back to auto-detection for subsequent -a options.

           For example:

            virt-filesystems --format=raw -a disk.img

           forces raw format (no auto-detection) for "disk.img".

            virt-filesystems --format=raw -a disk.img --format -a another.img

           forces raw format (no auto-detection) for "disk.img" and reverts to
           auto-detection for "another.img".

           If you have untrusted raw-format guest disk images, you should use
           this option to specify the disk format.  This avoids a possible
           security problem with malicious guests (CVE-2010-3851).

       -h
       --human-readable
           In --long mode, display sizes in human-readable format.

       --keys-from-stdin
           Read key or passphrase parameters from stdin.  The default is to
           try to read passphrases from the user by opening "/dev/tty".

       -l
       --long
           Display extra columns of data ("long format").

           A title row is added unless you also specify --no-title.

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

           Use -h if you want sizes to be displayed in human-readable format.
           The default is to show raw numbers of bytes.

           Use --uuid to display UUIDs too.

       --lvs
       --logvols
       --logical-volumes
           Display LVM logical volumes.  In this mode, these are displayed
           irrespective of whether the LVs contain filesystems.

       --no-title
           In --long mode, don't add a title row.

           Note that the order of the columns is not fixed, and may change in
           future versions of virt-filesystems, so using this option may give
           you unexpected surprises.

       --parts
       --partitions
           Display partitions.  In this mode, these are displayed irrespective
           of whether the partitions contain filesystems.

       --pvs
       --physvols
       --physical-volumes
           Display LVM physical volumes.

       --uuid
       --uuids
           In --long mode, display UUIDs as well.

       -v
       --verbose
           Enable verbose messages for debugging.

       -V
       --version
           Display version number and exit.

       --vgs
       --volgroups
       --volume-groups
           Display LVM volume groups.

       -x  Enable tracing of libguestfs API calls.

COLUMNS

       Note that columns in the output are subject to reordering and change in
       future versions of this tool.

       Name
           The filesystem, partition, block device or LVM name.

           For device and partition names these are displayed as canonical
           libguestfs names, so that for example "/dev/sda2" is the second
           partition on the first device.

           If the --long option is not specified, then only the name column is
           shown in the output.

       Type
           The object type, for example "filesystem", "lv", "device" etc.

       VFS If there is a filesystem, then this column displays the filesystem
           type if one could be detected, eg. "ext4".

       Label
           If the object has a label (used for identifying and mounting
           filesystems) then this column contains the label.

       MBR The partition type byte, displayed as a two digit hexadecimal
           number.  A comprehensive list of partition types can be found here:
           http://www.win.tue.nl/~aeb/partitions/partition_types-1.php

           This is only applicable for DOS (MBR) partitions.

       Size
           The size of the object in bytes.  If the --human option is used
           then the size is displayed in a human-readable form.

       Parent
           The parent column records the parent relationship between objects.

           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.

           If there is more than one parent, then this column is (internal to
           the column) a comma-separated list, eg. "/dev/sda,/dev/sdb".

       UUID
           If the object has a UUID (used for identifying and mounting
           filesystems and block devices) then this column contains the UUID
           as a string.

           The UUID is only displayed if the --uuid option is given.

NOTE ABOUT CSV FORMAT

       Comma-separated values (CSV) is a deceptive format.  It seems like it
       should be easy to parse, but it is definitely not easy to parse.

       Myth: Just split fields at commas.  Reality: This does not work
       reliably.  This example has two columns:

        "foo,bar",baz

       Myth: Read the file one line at a time.  Reality: This does not work
       reliably.  This example has one row:

        "foo
        bar",baz

       For shell scripts, use "csvtool" (http://merjis.com/developers/csv also
       packaged in major Linux distributions).

       For other languages, use a CSV processing library (eg. "Text::CSV" for
       Perl or Python's built-in csv library).

       Most spreadsheets and databases can import CSV directly.

SHELL QUOTING

       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.

EXIT STATUS

       This program returns 0 if successful, or non-zero if there was an
       error.
