Because sometimes less is more, I used a stripped-down version of your
configuration files:

> node01:
#  -*- mode: python; -*-
kernel="/boot/domU_64/vmlinuz-2.6.21-xxxx-xenU-ipv4-64"
memory = "256"
maxmem = "512"
name = "node02"
vcpus=1
vif = [ 'ip=10.0.0.2' ]         # replace with DomU's IP
ip = "10.0.0.2"
gateway= "10.0.0.128"                   # Dom0
netmask = "255.255.255.0"
disk = [ 'file:/xen/node01.img,hda1,w',
'file:/xen/node01-swap.img,hda2,w' ]

root = "/dev/hda1"

extra='console=xvc0 xencons=xvc0'
nographics=0

both boot up fine. I didn't test networking yet, but If you're going to
use only NAT-based machines and none using your "failover-IP" I
recommend changing /etc/xen/xend-config.sxp anyway (comment the route
lines at lines 161, 162 and activate the NAT-lines at 167, 168)

On the host, there is one vif per virtual interface. That is, if you
have a VM with more than 1 NIC, you'll see accordingly more vifs on the
host.
