Loose bridge network connectivity after upgrade from 3.1 to 3.4

Hello,

I have three nodes, each with internet access and internal network between them, witch is 10.10.10.0/24. After upgrading node1 from 3.1-24 to 3.4-6, my vm in 10.10.10.103 can still ping the host (10.10.10.1) but not other vm (10.10.10.21 for example). Before the upgrade, it was working fine.

I suspect a bridge routing problem; after googeling several hours I came here, my knoledge is limited, any idea are welcome...

I run debian weezy,
my interfaces file:
### Hetzner Online AG - installimage
# Loopback device:
auto lo
iface lo inet loopback

# device: eth0
auto eth0
iface eth0 inet static
address x.x.x.x
broadcast 144.76.196.223
netmask 255.255.255.224
gateway 144.76.196.193
# default route to access subnet
up route add -net 144.76.196.192 netmask 255.255.255.224 gw 144.76.196.193 eth0

iface eth1 inet manual
auto vmbr0
iface vmbr0 inet static
address 10.10.10.1
netmask 255.255.255.0
bridge_ports eth1
bridge_stp off
bridge_fd 0
# bridge_hello 2
# bridge_maxage 12

auto vmbr1
iface vmbr1 inet static
address 10.9.8.1
netmask 255.255.255.0
bridge_ports none
bridge_stp off
bridge_fd 0

To which bridge did you had the interfaces of the Virtual machines ? From your set up I understand you should the virtual interfaces to the vmbr0 bridge.

Yes it's on vmbr0
vmbr1 is almost not used.

In fact I check this issue in live with a good linux network knowledge guy during one our, and it's look very strange & complicated problem.
As I can understand: outgoing tcpip packets are send to vmbr0 instead of eth0.

We will look onto that next week-end and I will keep the list informed: in worse case I'm ready to reinstall the node but we want to know what's happend because I've somes other nodes to update.
