I have followed the instructions in http://wiki.xensource.com/xenwiki/XenParavirtOps /

Using Xen/paravirt_ops

Building with domU support

exactly ..

  1. Get a current kernel. The latest kernel.org kernel is generally a good choice.
   Done

   2. Configure as normal; you can start with your current .config file
   Done

   3. If building 32 bit kernel make sure you have CONFIG_X86_PAE enabled (which is set by selecting CONFIG_HIGHMEM64G)
   CONFIG_HIGHMEM64G=y,CONFIG_X86_PAE=y
   Done

          * non-PAE mode doesn't work in 2.6.25, and has been dropped altogether from 2.6.26 and newer kernel versions.
   4. Enable these core options:
         1. CONFIG_PARAVIRT_GUEST
         Done - CONFIG_PARAVIRT_GUEST=y
         2. CONFIG_XEN
         Done - CONFIG_XEN=y

   5. And Xen pv device support
         1. CONFIG_HVC_DRIVER and CONFIG_HVC_XEN
         Done - CONFIG_HVC_DRIVER=y
         Done - CONFIG_HVC_XEN=y
       
         2. CONFIG_XEN_BLKDEV_FRONTEND
         Done - CONFIG_XEN_BLKDEV_FRONTEND=y

         3. CONFIG_XEN_NETDEV_FRONTEND
         Done - CONFIG_XEN_NETDEV_FRONTEND=y

   6. And build as usual
      make oldconfig, make -j2 bzImage modules , make -j2 modules_install , make install

I think you are confusing Linux pvops from the git tree above and Xen. There are two seperate
products.

Look at http://wiki.xensource.com/xenwiki/XenParavirtOps
and pay especailly attention in the grub line. You NEED xen.gz in it.
