  Ideally, all versions of Xen in pkgsrc would build on all versions of
  NetBSD on both i386 and amd64.  However, that isn't the case.  Besides
  aging code and aging compilers, qemu (included in xentools for HVM

+     with NetBSD grub will also work).
+   * Push patches upstream.
+   * Get UFS2 patches into pvgrub.
+ * Add support for PV ops to a version of /boot, and make it usable as
+   a kernel in Xen, similar to pvgrub.
