-The ``sheepdog`` block device driver is deprecated. The corresponding upstream
-server project is no longer actively maintained. Users are recommended to switch
-to an alternative distributed block device driver such as RBD. The
-``qemu-img convert`` command can be used to liberate existing data by moving
-it out of sheepdog volumes into an alternative storage backend.

-Sheepdog disk images
-~~~~~~~~~~~~~~~~~~~~
-
-Sheepdog is a distributed storage system for QEMU.  It provides highly
-available block level storage volumes that can be attached to
-QEMU-based virtual machines.
-
-You can create a Sheepdog disk image with the command:
-
-.. parsed-literal::
-
-  qemu-img create sheepdog:///IMAGE SIZE
-
-where *IMAGE* is the Sheepdog image name and *SIZE* is its
-size.
-
-To import the existing *FILENAME* to Sheepdog, you can use a
-convert command.
-
-.. parsed-literal::
-
-  qemu-img convert FILENAME sheepdog:///IMAGE
-
-You can boot from the Sheepdog disk image with the command:
-
-.. parsed-literal::
-
-  |qemu_system| sheepdog:///IMAGE
-
-You can also create a snapshot of the Sheepdog image like qcow2.
-
-.. parsed-literal::
-
-  qemu-img snapshot -c TAG sheepdog:///IMAGE
-
-where *TAG* is a tag name of the newly created snapshot.
-
-To boot from the Sheepdog snapshot, specify the tag name of the
-snapshot.
-
-.. parsed-literal::
-
-  |qemu_system| sheepdog:///IMAGE#TAG
-
-You can create a cloned image from the existing snapshot.
-
-.. parsed-literal::
-
-  qemu-img create -b sheepdog:///BASE#TAG sheepdog:///IMAGE
-
-where *BASE* is an image name of the source snapshot and *TAG*
-is its tag name.
-
-You can use an unix socket instead of an inet socket:
-
-.. parsed-literal::
-
-  |qemu_system| sheepdog+unix:///IMAGE?socket=PATH
-
-If the Sheepdog daemon doesn't run on the local host, you need to
-specify one of the Sheepdog servers to connect to.
-
-.. parsed-literal::
-
-  qemu-img create sheepdog://HOSTNAME:PORT/IMAGE SIZE
-  |qemu_system| sheepdog://HOSTNAME:PORT/IMAGE
