    ive followed the howtoforge guide for debian etch repository xen install.

    ive got two network interfaces, for which eth1 is the one online.

    So i define (network-bridge network-script netdev=eth1) in xend-config.sxp.

    The problem is when i then boot up the xen kernel i cant get online with host(dom0) but the domains(domU) gets online. What have i forgotten?

    What's the output of
    route -nee
    on dom0? Any errors in the logs?

    cant copy/paste so i will give as much info as possible:

    ifconfig shows:

    eth1 - public ip adress
    lo -
    peth1 - no ip adress
    vif0.1, vif1.0, vif 2.0 and xenbr1 - no ipadresses

    route -nee shows eth1 in routes. one from gateway and one to gateway.

    cant understand how the vms can be online but not the host.

    What's in /etc/network/interfaces on dom0?

    allow-hotplug eth1
    iface eth1 inet static
    address <publicip>
    broadcast <broadcastip>
    gateway <gatewayip>

    was thinking about debugging the network-bridge script to see if i can get any errors.

    That's all? No loopback device (lo)?

    yeah sorry forgot that. lo as by default installed. any hints to what could be wrong. Should be the bridge right?

    Are there spaces in front of address, broadcast, netmask, and gateway? Can you post the whole file again and wrap it in code tags here (that's the # button in the editor here)?

    it works when im not booting xen kernel so i guess the problem has to lie somewhere else.
