[Xen-users] Getting the bridged network running on Debian Squeeze with Xen 4.0.1

["Taschik, Daniel" <Daniel.Taschik@xxxxxxxxxxxxxxxxxxxxxxxxxx>]

Hi,

For a few days, I have been trying  to get a Xen 4.0.1 running on a fresh 
installed Debian Squeeze 6.0.4. The host installation was fine at all. My 
problem is, that I can't get the network in the guest domU up and running. 

root@guest:~# ifconfig
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

root@guest:~# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 39:fa:a9:88:a1:5c  
          inet addr:192.168.67.14  Bcast:192.168.67.255  Mask:255.255.255.0
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
          Interrupt:23 

root@guest:~# ifconfig eth0 up
SIOCSIFFLAGS: Cannot assign requested address


On the Host, my xend-configuration.sxp looks like this:

(vif-script vif-bridge)
(network-script 'network-bridge bridge=eth0')
(dom0-min-mem 2048)
(enable-dom0-ballooning yes)
(total_available_memory 0)
(dom0-cpus 0)
(vncpasswd '').
(xend-unix-server yes)

brctl show looks like this:

bridge name     bridge id               STP enabled     interfaces
eth0            8000.002590499320       no              peth0
                                                                                
    vif1.0
My host dmesg log looks like this:

I created the guest with:

xen-create-image --force       --fs=ext4 --genpass=0 --install=1       
--memory=10G --password=test      --pygrub --size=20G --swap=4G      
--swap-dev=/dev/vg0/hostname.com-swap --vcpus=4       --dist=squeeze 
--install-method=debootstrap       --broadcast=192.168.67.127 
--netmask=255.255.255.128      --gateway=192.168.67.1 --ip=192.168.67.14 
--mac=39:fa:a9:88:a1:5c      --nameserver=192.168.67.1 --hostname=hostname.com  
    --lvm=vg0


I found out that when I disable handle_iptables() (line 94 in 
/etc/xen/scripts/vif-bridge), the errors about the physdev-out disappear, but 
even when this error is gone the problem is still the same. I tried using 
routed networking, but the same problem here. I have been reinstalling two 
times but no success at all. I hope you can help me to find out how to get the 
network in the guest running.

Thanks in Advance!

Daniel
