Xen users - Sep 2005 - network probs trying to get nfs root to work

Hi.  trying to get a domU (dom1) up using nfs root.  never done this
before  ;-).  I have dom0 up (2.6.12-xen0) and i have an external nfs
server with a nice root disk populated.  i get this after
xm create -c dom1 vmid=1

.
.
.
IP-Config: Complete:
      device=eth0, addr=172.31.205.229, mask=255.255.255.0,
gw=172.31.205.2,
     host=vm%d, domain=, nis-domain=(none),
     bootserver=161.144.120.208, rootserver=161.144.120.208, rootpathLooking up
port of RPC 100003/2 on 161.144.120.208
portmap: server 161.144.120.208 not responding, timed out
Root-NFS: Unable to get nfsd port number from server, using default

while it''s doing this i cant ping dom1 s addr (172.31.205.229) from
dom0.
what am i doing wrong?  any help is appreciated.

a snippet of my dom1 conf file:

# Set if you want dhcp to allocate the IP address.
#dhcp="dhcp"
ip=''172.31.205.229''
# Set netmask.
netmask=''255.255.255.0''
# Set default gateway.
gateway=''172.31.205.2''
# Set the hostname.
hostname= "vm%d"

# Set root device.
#root = "/dev/hda1 ro"

# Root device for nfs.
root = "/dev/nfs"
# The nfs server.
nfs_server = ''10.10.10.208''
# Root directory on the nfs server.
nfs_root   = ''/xen_root''





Cheers,
Anthony

Hmm, you configured 10.10.10.208 as nfs server, yet the kernel wants to 
nfs-mount from 161.144.120.208 ?

Thats kinda strange...

Maybe double-check the nfs_server options given in your domU config, and try 
if your NFS-Server can ping the domU while its booting up.

I would double check and make sure that you have all of the prereqs 
installed (bridge-utils, iptables, etc.).

You should also give a little more info on your setup (how many nics do 
you have in dom0 for instance).
