 Xen, the dom0 kernel, and each domU kernel can be either i386 or
 amd64.  When building a xenkernel package, one obtains i386 on an i386
 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

 i386 dom0 and domU kernels must be PAE (except for Xen 3.1); these are
