+  initialise [dev] [[ext_size]] - init. a physcial partition to store vd's
+  create [size] [[expiry]]      - allocate a vd of specified size (and expiry)
+  enlarge [vdid] [extra_size]   - enlarge a specified vd by some amount
+  delete [vdid]                 - delete a vd
+  import [filename] [[expiry]]  - create a vd and populate w/ image from file
+  export [vdid] [filename]      - copy vd's contents to a file
+  setexpiry [vdid] [[expiry]]   - update the expiry time for a vd
+  list                          - list all the unexpired virtual disks  
+  undelete [vdid] [[expiry]]    - attempts to recover an expired vd
