That's what you missed in the scheme: the xen scripts rename your real
network device card into peth0, and puts it into a bridge called eth0.
So you need to use the bridge called "eth0" in your PV scripts.

I update the Ubuntu's network configuration as
vif = ['bridge=eth0']

And after the Ubuntu booting, I set its IP as 192.168.1.20
However, I can access to the outside network.

root@ubuntu:~/test1# ping 61.135.169.125
connect: Network is unreachable

root@ubuntu:~/test1# ping 192.168.1.166
PING 192.168.1.166 (192.168.1.166) 56(84) bytes of data.
>From 192.168.1.129 icmp_seq=1 Destination Host Prohibited
From 192.168.1.129 icmp_seq=2 Destination Host Prohibited
From 192.168.1.129 icmp_seq=3 Destination Host Prohibited
From 192.168.1.129 icmp_seq=4 Destination Host Prohibited

But if PV use the virbr0 bridge, it can access to outside network successfully with IP 192.168.122.187.
