169.254/16 addresses are VMM-local: they're never allowed out on
the LAN.

For your purposes of accessing an external NFS server use some
other subnet e.g. 192.168/16.

(If you're using Xen 1.2, still give dom0 the 169.254.1.0 alias
so that you can get the console. Console works totally
differently in 1.3 so this is no longer required.)
