   4
   5     <p>
   6       The storage management APIs are based around 2 core concepts
   7     </p>
   8     <ol>
   9       <li>
  10         <strong>Volume</strong> - a single storage volume which can
  11         be assigned to a guest, or used for creating further pools. A
  12         volume is either a block device, a raw file, or a special format
  13         file.
  14       </li>
  15       <li>
  16         <strong>Pool</strong> - provides a means for taking a chunk
  17         of storage and carving it up into volumes. A pool can be used to
  18         manage things such as a physical disk, a NFS server, a iSCSI target,
  19         a host adapter, an LVM group.
  20       </li>
  21     </ol>
  22
  23     <p>
  24       These two concepts are mapped through to two libvirt objects, a
  25       <code>virStorageVolPtr</code> and a <code>virStoragePoolPtr</code>,
  26       each with a collection of APIs for their management.
