address@hidden 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:
address@hidden
+qemu-img create sheepdog:@var{image} @var{size}
address@hidden example
+where @var{image} is the Sheepdog image name and @var{size} is its
+size.
+
+To import the existing @var{filename} to Sheepdog, you can use a
+convert command.
address@hidden
+qemu-img convert @var{filename} sheepdog:@var{image}
address@hidden example
+
+You can boot from the Sheepdog disk image with the command:
address@hidden
+qemu sheepdog:@var{image}
address@hidden example
+
+You can also create a snapshot of the Sheepdog image like qcow2.
address@hidden
+qemu-img snapshot -c @var{tag} sheepdog:@var{image}
address@hidden example
+where @var{tag} is a tag name of the newly created snapshot.
+
+To boot from the Sheepdog snapshot, specify the tag name of the
+snapshot.
address@hidden
+qemu sheepdog:@var{image}:@var{tag}
address@hidden example
+
+You can create a cloned image from the existing snapshot.
address@hidden
+qemu-img create -b sheepdog:@var{base}:@var{tag} sheepdog:@var{image}
address@hidden example
+where @var{base} is a image name of the source snapshot and @var{tag}
+is its tag name.
+
+If the Sheepdog daemon doesn't run on the local host, you need to
+specify one of the Sheepdog servers to connect to.
address@hidden
+qemu-img create sheepdog:@var{hostname}:@var{port}:@var{image} @var{size}
+qemu sheepdog:@var{hostname}:@var{port}:@var{image}
