It seems that pygrub doesn't support XFS which is probably why I am
receiving this message.  I found
http://article.gmane.org/gmane.comp.emulators.xen.user/36999 and also
looking in /usr/lib/fs seems to confirm this.

Christian - thanks for your help but it seems I can't use pygrub unless
I change my fs.
