Attempting to build hash of hashes

hash_of_hashes.rb

    def build_virtual_boards_hash(board, player)
      virtual_boards_hash = {}
      new_board_hash = {}
      virtual_board = board.dup
      empty_spaces_on_board = virtual_board.grid.select{ |k, v| v == " " }.keys
      index_mark = 'VB'+empty_spaces_on_board.length.to_s

      while empty_spaces_on_board.length >= 1
        empty_spaces_on_board.each do |empty_space_symbol|
          
          p new_board_hash = move_as_somebody(board, player, empty_space_symbol, index_mark)
          build_virtual_boards_hash(board, player)
          
        end
      end
    end

---------------------
input is...
      @player = "X"
      @board.grid[:a1] = "X"
      @board.grid[:a2] = " "
      @board.grid[:a3] = " "
      @board.grid[:b1] = " "
      @board.grid[:b2] = "O"
      @board.grid[:b3] = " "
      @board.grid[:c1] = " "
      @board.grid[:c2] = " "
      @board.grid[:c3] = " "



---------------------

I need as output something as such...

virtual_board_hash => {
{"VB7"=>#<Board:0x007f9ab388f018 @grid={:a1=>"X", :a2=>"X", :a3=>" ", :b1=>" ", :b2=>"O", :b3=>" ", :c1=>" ", :c2=>" ", :c3=>" "}>}

{"VB5"=>#<Board:0x007f9ab388f018 @grid={:a1=>"X", :a2=>"X", :a3=>"X", :b1=>"X", :b2=>"O", :b3=>" ", :c1=>" ", :c2=>" ", :c3=>" "}>}
{"VB4"=>#<Board:0x007f9ab388f018 @grid={:a1=>"X", :a2=>"X", :a3=>"X", :b1=>"X", :b2=>"O", :b3=>"X", :c1=>" ", :c2=>" ", :c3=>" "}>}
{"VB3"=>#<Board:0x007f9ab388f018 @grid={:a1=>"X", :a2=>"X", :a3=>"X", :b1=>"X", :b2=>"O", :b3=>"X", :c1=>"X", :c2=>" ", :c3=>" "}>}
