Right, so vhost isn't a pluggable driver in the sense that pmds are. I 
wont claim to be familiar with all this virt-related puzzle pieces :) 
I'll send an updated patch, I was just looking to fix build in my 
particular config and ignored the rest.

On a related note, shouldn't librte_pmd_bond and librte_pmd_xenvirt be 
included in the plugins section along with all the other pmds?
