[Xen-users] Not able to get eth0 up on domU.

["Atul Dambalkar" <atul_dambalkar@xxxxxxxxxxxx>]

I am using ttylinux-xen file system image a a loopback device for the domain. I am mostly using the default configuration. I am not able to get networking on the domU. Are kernel "vmlinuz-2.6-xenU" as well as "2.6.11.12-xen0" both compiled w/o loadable module support? I guess it fails when it tries to initialize the iptables on the domU when it tries to do "modprobe". I do have connectivity on dom0. Am I doing anything wrong?

Here are all the details about domU:

 

==============domain configuration file==============

kernel = "/boot/vmlinuz-2.6-xenU"
memory = 64
name = "ttylinux"

vif = [ 'mac=aa:01:02:05:0B:11, bridge=xen-br0' ]

disk = [ 'phy:/dev/loop0,sda1,w' ]
