Still puzzled but with more info.

it seems when trying to use an NFS root the system never sends a
DHCPDISCOVER, which it does do when using the user space dhcp aafter
booting from "disk":

Sep 7 10:37:29 foghorn-leghorn dhcpd: DHCPDISCOVER from
aa:00:80:1e:02:89 via eth0

It starts right out with:

Sep  7 10:33:40 foghorn-leghorn dhcpd: DHCPREQUEST for 255.255.255.255
(1.2.3.4) from aa:00:80:1e:02:89 via eth0: ignored (not
authoritative).


Well of course my server isn't giving out anything on that network....


Must be a config issue so here's the whole thing:

---

kernel = "/boot/vmlinuz-2.6.16-xen0"
memory = 3560
name = "il4"
vif = [ 'mac=aa:00:80:1e:2:89, bridge=xenbr0']
disk = [ 'file:/xen/disks/il4-root,sda1,w',
         'file:/xen/disks/il4-swap,sda2,w',
         'file:/xen/disks/il4-openafs,sda3,w', ]
#root = "/dev/sda1 ro"
dhcp="dhcp"
root="/dev/nfs"

---

I must be missing something...
