[Xen-users] DomU routed traffic disappearing in vif.

[Matej Zary <zary@xxxxxxxxx>]

Hello,


XEN 4.0 with pvops 2.6.32.11 Dom0 kernel. Configured PV DomU with the same 
pvops Xen kernel on top of it.

Physical computers has 3 NICs - every NIC in own bridge (first one created by 
Xen).

eth0            8000.00138fe78f1b       no              peth0
mst1            8000.0040f4b5286e       no              eth1
                                                        vif5.0
mst2            8000.000e2e68db10       no              eth2
                                                        vif5.1

Attached 2 virtual NICs to the PV DomU and bridges - I want to use that DomU as 
router between that two bridges (enabled ip_forwarding in DomU) - mst1 and mst2.

I can ping from netwok on eth1 the vif5.0 interface.
I can ping from network on eth2 the vif5.1 interface.
I can see with tcpdump, that the DomU routes the traffic between its eth0 and 
eth1 interfaces (tcpdump inside the domu).
I can see with tcpdump the incoming traffic in mst1 and vif5.0.
But there's nothing on the vif5.1and mst2 bridge - even when tcpdump on the 
eth1 in that PV DomU shows the routed traffic ("works"  the same in opposite 
direction too).

Looks like all traffic routed by that PV DomU cant't get from DomU eth 
interface to the vif interface. Ping from the DomU works (non routed traffic), 
but no routed traffic can get thu this Dom0.

IPltables flushed with -F 

Thanks for every idea, i'm clueless right now. :(

Regars
