I'm sorry if this sounds like a really stupid question but I started today for the first time using Xen. I'm using it on a fresh installation of Debian Lenny. I followed this tutorial http://www.howtoforge.com/virtualization-with-xen-on-debian-lenny-amd64 but the 686 version, non the amd64.

The problem is that after enabling the bridge, it can't seem able to find my router dhcp server. Is there something I'm missing? On ifconfig I have eth0, peth0 and lo.

I mean the physical computer in not connected. I can't even start creating domU because of the absence of connection.

So apparently there is connection. The problem is in the bridge.

What response do you get from dhclient. Can you connect to your router if you configure the ethernet devices with static IPs? –  pacey Nov 5 '10 at 10:14
    
can you show your ifconfig output as well as route output please? –  Khushil Nov 5 '10 at 10:29
    
@pacey: no I can't connect to anything. I can connect when I don't use xen-kernel. –  dierre Nov 5 '10 at 11:53
    
additionally please post the output of cat /etc/xen/xend-config.sxp |grep network-script. Also check lspci for the network adapter. If the problem is not present under a non-XEN-kernel you should compare the output of lsmod for both kernels. –  pacey Nov 5 '10 at 12:19
