[Xen-users] broken networking - bridge

[Damir Špoljarič <admin@xxxxxxxxxx>]

Hi all,
  
   I have a problem with network in bridge mode. Everything went well, 
but for unkown reason network stopped to work on virtual machines.
One virtual machine has IP for example 82.208.36.96. I can´t get on it 
from the network (I mean Internet :-) ) and I also can´t from virtual 
machines get to Internet. I can get on virt. mach. only from domain0. 
Something with bridge has probably broken :-/. Brctl show looks normal:
bridge name     bridge id               STP enabled     interfaces
xenbr0          8000.feffffffffff       no              peth0
                                                                  vif0.0
                                                                  vif4.0

Ifconfig output looks normal as well. There are interfaces eth0, peth0, 
xenbr0, vif0, vif1.0.
I haven't edited scripts vif-bridge and network-bridge at all. They are 
default, as well as xend config.
These are individual domU configs (about network):
nics=1
dhcp ="off"
ip="82.208.36.96"
netmask="255.255.255.0"
gateway="82.208.36.1"

All rules in iptables are set to ACCEPT (OUTPUT, INPUT and FORWARD).
In addition to this, I have something in FORWARD:
ACCEPT     all  --  anywhere             anywhere            PHYSDEV 
match --physdev-in vif1.0
There are no errors in logs. Only in xen-hotplug.log is this:
xenstore-read: couldn't read path backend/vif/1/0/ip
xenstore-read: couldn't read path backend/vbd/1/770/physical-device
xenstore-read: couldn't read path backend/vif/1/0/bridge

Thanks !
