I think that /sys is clearly the right place to put information about 
Xen, including version, domains and domain info, and perhaps info about 
xenstore. This is according to feedback received when I submitted my 
first (braindead) patch moving /proc/xen to /proc/sys/xen.

Still I agree that we need input from lkml and am going to cross-post an 
  RFC so we can move forward.

Mike
