Steps to Reproduce:
1. First create a disk pool in virt-manager

# virsh pool-dumpxml disk
<pool type='disk'>
  <name>disk</name>
  <uuid>10704474-12dd-a75a-fc88-02f9edb07a91</uuid>
  <capacity>500105249280</capacity>
  <allocation>0</allocation>
  <available>500105248768</available>
  <source>
    <device path='/dev/sdb'>
    <freeExtent start='512' end='500105249280'/>

    </permissions>
  </target>
</pool>

2. In disk pool, click New Volume button to create a vol

  
Actual results:

An error display:
Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/host.py", line 479, in add_vol
    self.addvol = vmmCreateVolume(self.config, self.conn, pool)
  File "/usr/share/virt-manager/virtManager/createvol.py", line 59, in __init__
    self.vol_class = Storage.StoragePool.get_volume_for_pool(parent_pool.get_type())
  File "/usr/lib/python2.4/site-packages/virtinst/Storage.py", line 236, in get_volume_for_pool
    return pool_class.get_volume_class()
  File "/usr/lib/python2.4/site-packages/virtinst/Storage.py", line 585, in get_volume_class
    raise NotImplementedError(_("Disk volume creation is not implemented."))
NotImplementedError: Disk volume creation is not implemented.
