Re: [Xen-users] Xen networking problem

Hallo Henning,

Thanks for answering.

> All the output you sent is quite useless to diagnose your problem -

At least the useless data helped someone else to point out a typo on my
side concerning the netmask (255.255.255.254 in stead of 255.255.254.0).

But that did not solve the problem.  At least I can get eth0 running
now.

I will remember.

> Please show us ifconfig eth0 in the domU 


eth0      Link encap:Ethernet  HWaddr 00:16:3E:10:BE:13

Is this what you are talking about (/etc/xen/vmmail.sun.ac.za.cfg in
this case)?

vif  = [ 'ip=192.168.1.200' ]

I do not understand your question, sorry.

A tail of /var/log/messages on dom0:

Nov 15 07:21:19 blackbird kernel: eth0:  setting full-duplex.

And on domU:

Also on domU:

$ dmesg | grep eth0
eth0: no IPv6 routers present
