[Xen-users] NIC not working inside guest

["Yvo van Doorn" <yvo.vandoorn@xxxxxxxxx>]

Hey everyone,

I am trying to kickstart a Xen guest (CentOS 5) and this has worked
fantastically on one of two HP DL360G5s. Both run Xen 3.2.0 with
CentOS 5. It works without an issue on one machine and I have 4 CentOS
5 Xen guests running without a hitch but I am having a heck of a
problem doing the same exact thing on the 2nd host. Basically I try to
kickstart CentOS5 and it will stop at the "Sending request for IP
information for eth0..." and bring up a "Configure TCP/IP" text based
dialog. It is just not able to download the kickstart file as its not
making a network connection. What is even more frustrating is the
inability to do Alt+F3 to see the verbose output (sticky keys or
not... this is just not working when viewing the installation via xm
console). So I am completely blind on the guest side. I see no DHCP
request on the dhcp server (it is on the same subnet) and no request
on the http server where the kickstart file is hsoted.

Any help on this would be great.

 The Dom0 has this in the /var/log/messages:
