Hello,

my domain-0 loses it network when xend starts.
It uses a dhcp client on eth0 to receive its ip address (192.168.1.2). 

If I run 
$ dhclient xen-br0
$ /etc/init.d/networking restart

then I have the network, but route shows now two routes to 192.168.1.0:
$ LANG=EN route -n
Kernel IP routing table
Destination     Gateway        Genmask         Flags Metric Ref    Use Iface
192.168.1.0     0.0.0.0        255.255.255.0   U     0      0        0 xen-br0
192.168.1.0     0.0.0.0        255.255.255.0   U     0      0        0 eth0
0.0.0.0         192.168.1.1    0.0.0.0         UG    0      0        0 xen-br0

Does anyone know what is the correct way to make this work?


A second problem: I cannot ping to domU.

I think the problem is that there is no IP4-address assigned to to the vif 
interface. But assigning an ip address with ifconfig didn't help

Here is the output from ifconfig after I started my domU:

I searched for both problems in the mailing list but couldn't find anything 
that helped me.

I attached the config for the domU.
My /etc/network/interfaces looks like this:
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
        address 192.168.5.2
        netmask 255.255.255.0
        network 192.168.5.0
        gateway 192.168.5.1

route on domU gave:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.5.0     *               255.255.255.0   U     0      0        0 eth0

ifconfig on domU gave

I use Adam Heath's latest (2.0.4-4) packages from 
http://people.debian.org/~doogie/packages/ on debian sarge

Thanks a lot for your help
