Hi,
Many thanks to your reply. But there has to be something else different
with xen-2.0. I didn't compile the loopback as you suggested. Now
it's close to work until the DomU boots.
The strange thing is that domU and dom0 both can talk to the whole world
but they can NOT talk to each other. They can even ping each other but
cannot ssh. (I use the same disk image as I use for xen-2.0 so I don't
think there is some forwarding policy problem, etc. And actually I turned
off all the firewall, security things)
Here is the route table of dom0 after domU boots:
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
9.2.72.0 0.0.0.0 255.255.255.128 U 0 0 0 xen-br0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 xen-br0
0.0.0.0 9.2.72.1 0.0.0.0 UG 0 0 0 xen-br0
And ifconfig of dom0:
eth0 Link encap:Ethernet HWaddr 00:0D:60:9A:15:60
 inet addr:9.2.72.112 Bcast:9.2.72.127 Mask:255.255.255.128
lo Link encap:Local Loopback
 inet addr:127.0.0.1 Mask:255.0.0.0
vif1.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF
 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
xen-br0 Link encap:Ethernet HWaddr 00:0D:60:9A:15:60
 inet addr:9.2.72.112 Bcast:9.2.72.127 Mask:255.255.255.128
ifconfig of domU:
eth0 Link encap:Ethernet HWaddr AA:00:00:00:00:1ame:0
 inet addr:9.2.72.101 Bcast:9.2.72.127 Mask:255.255.255.128
lo Link encap:Local Loopback
 inet addr:127.0.0.1 Mask:255.0.X packets:18 errors:0 dropped:0
It's almost working but it seems that something is preventing those two OS
on the same machine talking to each other.
Do you have any ideas? Thank you very much!

Wei Huang
