  Yes, you will need to enable it since it isn't enabled by default.

  Yes - and it is that kernel which needs it enabled in.

  By default the Xen kernel which is installed by "make world && make
 install" doesn't have NFS_ROOT setup.  Neither do many of the kernels
 packaged by distributions.  (eg. Debian Etch has a range of Xen kernels
 but none of them have NFS_ROOT compiled in).

  By happy coincidence I wrote a guide on getting NFS_ROOT working
 on a Debian machine yesterday evening and it just got published:

        http://www.debian-administration.org/articles/505

  In short:

    1.  Get the Xen source, so you can rebuild a xen kernel and 
       install it to /boot
    2.  Setup NFS server.
    3.  Create Xen configuration file beneath /etc/xen

  No need to use an initrd image in the common cases, unless you need
 funky hardware support.  Just compile NFS into the kernel rather than
 as a module and you'll be fine.

  Hope that helps a little.

Steve
