[Xen-users] Ubuntu 9.10: amd64: Xen-4.0: linux-2.6.32.16-xen: No Network connectivity in domU:

[sriram <msriram@xxxxxxxxxx>]

Hi people, 
I installed Xen-4 on top of karmic-amd64 using this method, and created dom1 using debootstrap, and its booting fine.
But, I cannot get networking work on domU

I have single system, eth0 connected to network
/etc/network/interfaces/ :
auto lo
iface lo inet loopback
iface eth0 inet dhcp

I have the following info in the dom1.cfg:
#
#  Networking
#
vif	   = ['']
dhcp        = 'dhcp'
#vif         = [ 'mac=00:16:3E:05:7D:B5' ]
netmask	    = "255.255.255.0"
gateway	    = "137.82.252.254"
 #

>From dom0
When I type route I get
#route
Kernel IP routing table
