I did post yesterday to get a working setup with several bridged interfaces used for virtual machines (KVM/libvirt).

That setup is working but not all the time ! I can start a download from a vm, then it will stop and freeze!

So I don't know if my bridge parameters are correct, could you check the below config ?

```
iface eth3 inet manual

auto bond0
iface bond0 inet manual
    slaves eth1 eth2
    pre-up ip link set bond0 up
    down ip link set bond0 down

auto br0
iface br0 inet static
    address 10.160.0.7
    netmask 255.255.255.128
    bridge_ports eth3
    bridge_fd 9
    bridge_hello 2
    bridge_maxage 12
    bridge_stp on

auto br0:1
iface br0:1 inet static
    address 10.160.0.9
    netmask 255.255.255.255

auto br0:2
iface br0:2 inet static
    address 10.160.0.10
    netmask 255.255.255.255

auto br1
iface br1 inet static
    address 217.4.40.242
    netmask 255.255.255.240
    gateway 217.4.40.241
    pre-up /etc/network/firewall start
    bridge_ports bond0
    bridge_fd 9
    bridge_hello 2
    bridge_maxage 12
    bridge_stp on

auto br1:1
iface br1:1 inet static
    address 217.4.40.252
    netmask 255.255.255.255

auto br1:2
iface br1:2 inet static
    address 217.4.40.253
    netmask 255.255.255.255

```

And yes, it also sometimes speaks about martian on the host:

```
kernel: [249146.055172] martian source 10.160.0.17 from 10.160.0.10, on dev vnet2
kernel: [249146.073122] ll header: ff:ff:ff:ff:ff:ff:54:52:00:76:c3:5c:08:06

```
