No no no, please no. The current scheme is good because there are clear 
key,value pairs for each individual configuration option. A generic blob
of dm_args will be a huge PITA to deal with, making a mockery of the
attempt at clearly modelling guest config params in XenAPI, as well as the 
legacy config formats. It will also increase the divergance in the way
HVM guests are configured vs paravirt guests if we start to shove all the
HVM args into 'dm_args' rather than representing them in a way which works
well for both HVM and PV domains.
