from the README:

" These are smaller builds with just selected
  modules, intended primarilly for developers that don't like to wait
  for a -xen kernel to build. The -xenU kernel is particularly small
  as it does not contain any physical device drivers, and hence is
  only useful for guest domains."

correct me here, but does that mean for a typical rollout you want to
just build the xen kernel, and not the xenU/xen0 ??

reason I ask, is that it seems to be the standard practice to build
both, but that isnt quite what I interpret from the notes.

If anyone can point to or summarize some performance benefits for
either route, that would be great.

Thanks
