   host, and amd64 on an amd64 host.  If the xen kernel is i386, then the
   dom0 kernel and all domU kernels must be i386.  With an amd64 xen
   kernel, an amd64 dom0 kernel is known to work, and an i386 dom0 kernel
   should in theory work.  An amd64 xen/dom0 is known to support both
   i386 and amd64 domUs.
   
   i386 dom0 and domU kernels must be PAE (except for Xen 3.1); these are

   with PAE when built without, and vice versa, presumably due to bugs in
   the undump code.)
   
   Because of the above, the standard approach is to use amd64 for the

   Hardware known to work
   ----------------------
   
   Arguably, this section is misplaced, and there should be a page of
   hardware that runs NetBSD/amd64 well, with the mostly-well-founded
   assumption that NetBSD/xen runs fine on any modern hardware that
   NetBSD/amd64 runs well on.  Until then, we give motherboard/CPU/RAM
   triples to aid those choosing a motherboard.  Note that Xen systems
   usually do not run X, so a listing here does not imply that X works at
   all.
