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

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?

Greping for module on Cambrige complied domU config gives me

grep -ir module /boot/config-2.6.11.10-xenU
# Loadable module support
CONFIG_MODULES=y
CONFIG_MODULE_UNLOAD=y
# CONFIG_MODULE_FORCE_UNLOAD is not set
# CONFIG_MODULE_SRCVERSION_ALL is not set

As for iptables(if you need) , you need to re-compile domU kernel and copy
/lib/modules/<the righ domU kernel version> into the domU''s root
fs.

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

Try static IP address and netmask in domU config.

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

I want to use dhcp for now rather than static ip. I will try it first by
not having iptables.
 
Thanks for your inputs.
