+@item SSH
+QEMU supports SSH (Secure Shell) access to remote disks.
+
+Examples:
+@example
+qemu-system-i386 -drive file=ssh://user@@host/path/to/disk.img
+qemu-system-i386 -drive file.driver=ssh,file.user=user,file.host=host,file.port=22,file.path=/path/to/disk.img
+@end example
+
+Currently authentication must be done using ssh-agent. Other
+authentication methods may be supported in future.

@item Sheepdog
Sheepdog is a distributed storage system for QEMU.
QEMU supports using either local sheepdog devices or remote networked
@option{passthrough}.
The specific backend type will determine the applicable options.
-The @code{-tpmdev} option requires a @code{-device} option.
+The @code{-tpmdev} option creates the TPM backend and requires a
+@code{-device} option that specifies the TPM frontend interface model.
Options to each backend are described below.
