This function confuses me a bit. It takes a virStoragePoolPtr as parameter, but it only uses pool->conn. The other two virStorageVolLookupBy* functions take a virConnectPtr directly.

There are 3 levels of unique identifiers in storage volumes

  - name - unique within the scope of a Pool
  - key - unique across any machine accessing the same pool
  - path - unique within scope of a host (optionally across any host,
           if the pool impl supports that).

So, since name is unique within scope of a volume, while the others
are unique within scope of a host, the virStorageVolLookupByName
method is different, taking a virStoragePoolPtr instead of a virConnectPtr.

A few examples would go a long way to helping me understand this. Can you give examples of name/key/path in the context of iscsi/partition/directory?
