Resending, since my e-mail does not seem to have gone through in 13 and 24
hours. Sorry if it dupes. I'm attaching the logs this time. Maybe there is a
max limit to how long an e-mail can be?

Hi all,

I have installed a Debian 4.0 (newly released), compiled and installed Xen.
All went as I am used to from Ubuntu.

I created a new guest with Debian Etch debootstrap, and it boots without
problems. But it can not fetch an IP address from my DHCP server
(10.13.15.1). When I use TCPDump on xenbr0, it only shows the requets being
transmitted but nothing is recieved. 

I hope I have included all relevant information below, and I hope someone
can help me where to look for the cause. I have searched widely in the Wiki,
google and mailinglist.

Once I suceed, I will post an new article on the Wiki with a step-by-step
guide to compiling and installing Xen from source on Debian 4.0.

Thank you very much in advance

Best regards
Nicolai
