  Right ... specific <topology .../> line should not be there.  It sneaked in
  because i was playing with code supporting topology and unfortunate forgot
  to delete specific line in the test.  Reason i forgot is that specific line
  does _NOT_ cause any issue to testing as for 'fullvirt-vnuma-nodistances'
  the CANONs can only go one-way (domxml to native).

  Going backwards (domxml from native) would create XML topics listing,
  ignorant, default distances generated making the -nodistance CANON match
  fail its xml representation.

  Indeed ... <topology/> was not suppost to be in.  Thanks for spotting this
  one. I'll remove it under v2.
