   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.
   
   Except for an odd case with Xen 3.1, i386 dom0 and domU kernels must
   be PAE; these are built by default.  (Note that emacs (at least) fails

   Because of the above, the standard approach is to use amd64 for the

 One can then run i386 domUs and amd64 domUs, in any combination.  If
