I'm no expert on such things, but I'm not sure you want to give the 
virtual machine access to all 24 cores.  It might be better to leave one 
or two dedicated to running the underlying OS.  Still, you certainly 
should be able to get more than one or two cores into the act.  I'll be 
interested in seeing the suggestions from the more knowledgeable members 
of this list.
