Package: linux-image-2.6.18-4-xen-amd64
Version: 2.6.18.dfsg.1-11

For a xen installation on a sun fire 4200m2 I tried to bridge a vlan on eth0 (forcedeth-driver) with a vifx.x of one of the domUs. The network of the domU does not work at all.

I use the following custom script (peth0 is the renamed eth0)

# vlan 1103
                if ! `lsmod | grep -q 8021q` ; then modprobe 8021q ; fi
                vconfig add peth0 1103

                brctl addbr xenbr103
                brctl stp xenbr103 off
                brctl setfd xenbr103 0
                ip link set xenbr103 arp off
                ip link set xenbr103 multicast off
                ip link set peth0.1103 up
                brctl addif xenbr103 peth0.1103
                ip link set xenbr103 up

the xen script add the vif interface when I start the domU.

# brctl show
bridge name     bridge id               STP enabled     interfaces
xenbr0          8000.feffffffffff       no              vif0.0
                                                        peth2
xenbr103                8000.feffffffffff       no              peth0.1103
                                                        vif2.0


if I look at the macs I cannot see the router
# brctl showmacs xenbr103
port no mac addr                is local?       ageing timer
  2     00:16:3e:25:05:bc       no                24.74
  1     fe:ff:ff:ff:ff:ff       yes                0.00

On eth2 (an interface with e1000 driver) the same configuration works. A bridge without a vlan works and a vlan without bridge works too.

I am using:
