[Xen-devel] Networking problems with debian packages
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
default 192.168.5.1 0.0.0.0 UG 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
