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.

It is also in the storage_driver.c - storageVolumeLookupByName
