Revision 96ede451

fixes #1574 - ovirt - add remove and show volumes

volume and interface ordering is now working
removed include blank because it is a duplicate of the Blank ovirt-template.
bootable is disabled when editing a vm, because currently I don't handle volume updates. just add and remove of a volume.
Volumes are created in the order that they where created in the gui. Bootable is set by default to the first volume.
update to the latest rbovirt gem.

         (0...n).map { chars[rand(chars.length)].chr }.join
       end
       def nested_attributes_for type, opts
         return [] unless opts
         opts = opts.dup #duplicate to prevent changing the origin opts.
         opts.delete("new_#{type}") # delete template
         # convert our options hash into a sorted array (e.g. to preserve nic / disks order)
         opts = opts.sort { |l, r| l[0].sub('new_','').to_i <=> r[0].sub('new_','').to_i }.map { |e| Hash[e[1]] }
         opts.map do |v|
           if v[:"_delete"] == '1'  && v[:id].nil?
             nil
           else
             v.symbolize_keys # convert to symbols deeper hashes
           end
         end.compact
       end
     end
