Commands

list
^^^^

| :command:`qvm-volume list` [-h] [--verbose] [--quiet] [-p *POOL_NAME*] [*VMNAME* [*VMNAME* ...]]

List block devices. By default the internal devices are hidden. When the
stdout is connected to a TTY `qvm-volume list` will print a pretty table by
omitting redundant data. This behaviour is disabled when `--full` option is
passed or stdout is redirected to a pipe or file.

.. option:: -p, --pool

   list volumes from specified pool

.. option:: --full

   print domain names

.. option:: --all

   List volumes from all qubes. You can use :option:`--exclude` to limit the
   qubes set. Don't forget — internal devices are hidden by default!

.. option:: --exclude

   Exclude the qube from :option:`--all`.

aliases: ls, l

info
^^^^
| :command:`qvm-volume info` [-h] [--verbose] [--quiet] *VMNAME:VOLUME* [*PROPERTY*]

Show information about given volume - all properties and available revisions
(for `revert` action). If specific property is given, only its value is printed.
For list of revisions use `revisions` value.

aliases: i

config
^^^^^^
| :command:`qvm-volume config` [-h] [--verbose] [--quiet] *VMNAME:VOLUME* *PROPERTY* *VALUE*

Set property of given volume. Properties currently possible to change:

  - `rw` - `True` if volume should be writeable by the qube, `False` otherwise
  - `revisions_to_keep` - how many revisions (previous versions of volume)
   should be keep. At each qube shutdown its previous state is saved in new
   revision, and the oldest revisions are remove so that only
   `revisions_to_keep` are left. Set to `0` to not leave any previous versions.
